Why SQLite?
SQLite is the most used and preferred database software for web and mobile developers. This is because it is an open and free source, and it provides quite simple and server less set up.

What exactly is SQLite?
SQLite is a transactional, zero-configuration, public domain SQLite database software, or engine. It means SQLite is a complete mechanism available for web or app developers where they can store their data in a structured way, and along with this, they also get access to the source code as it is free and open source.

SQLite as a local database in xamarin . Forms are perfectly fit for a simple reason as it is readily available on both Android and iOS. This all means that you can use SQLite technology whenever you need to write a xamarin. Forms app.
SQLite is a zero-configured trading software or engine owned by SQLite. This means that SQLite is a complete mechanism available to web or application developers in which they can store their data structurally, as well as access free and open source code.
So, with SQLite, you will have the ability to put database features or functionality to your Xamarin. Forms app to retrieve and store any type of data easily.

One of the most basic needs is the ability to store and retrieve information. This can be implemented and set up using different tools on different platforms. SQLite is another data storage and retrieval tool known for its unique features. These features include power, free and support for all operating systems such as Windows, Linux, Mac, Android and iOS. SQLite data storage and retrieval tool is programmed in C language, and it is also a software that has a Public Domain license, which means that this tool is not owned by any organization or individual. It is not limited and everyone can use it without any restrictions.

Save information
Every application developer cares about data storage, whether it is a game application or any other type of application. This data can be statistics from the user or any other type of data that your user or you will need at some point in using the application.

Do you know that you have decided to use xamarin? Forms the path, then you must save your user data in your application. The solution to this problem is SQLite.

SQLite database
Steps to use SQLite in Xamarin. Forms

1. In the first step, what you do is to create a file of the SQLite database right directly in the Xamarin. Forms or if you already have a pre-created SQLite database file, then use it and insert it in your app.
2. Next, you link your
SQLite database file to both iOS and Android platforms specific project in Xamarin.Forms.
3. Connect SQLite.Net-PCL to every project in a solution of your xamarin. Forms.
4. From the app bundle, copy the database's file and put it on the writable place on the file system of your mobile device. And then open this file for writing and reading and to implement it on the Android and iOS platforms in order to do this step.
5. Create a model that matches the table definitions of SQLite Database in the Xamarin shared, common code base specific project
6. In the last step, you will have to create an SQLite connection and Database Access class in the Xamarin common code base project to perform CRUD operations on the database. Use results to bind the list of your XAML views.

Use SQLite.NET in Xamarin. Forms
To use Xamarin . Forms, you need to know some concepts in advance so that you can easily use the SQLite.NET database in Xamarin. Forms.
Depending on the format you choose for your project, different approaches are used to integrate SQLite.NET:

PCL Solution:
PCL solutions can easily be referred to SQLite classes. This reference can be easily done using
SQLite.NET PCL NuGet packages and can be combined with common code in the database. Xamarin. Forms Dependency Service can be used to connect to the SQLite database.

Collaborative projects:
Collaborative projects projects are integrated directly with the Net resource via GitHub and are referred to SQLite database classes through the combination with these resources.

Compile commands are used to use code for specific platforms, meaning that in order to be able to use the code on a different and specific platform, compiler commands must be used. Most code in SQLite.NET can be shared on other platforms and can be shared on other platforms, all you have to do is set up the database connection with each platform and then the location. Specify the SQLite database file. After this, you can easily share and use all the code in the SQLite database on all platforms.

How to build a new project and add SQLite support?

1- Create a new project for example called XamarinSqliteSample
2. Add a new package called SQLite.Net to the created project (this package will act as a cover for SQLite that allows access to all native SQLite features through Xamarin.Forms PCL or Shared Project and makes it possible.) 3. To add SQLite.Net support, right-click on the project name and select Manage NuGet Packages.
4. Select and install SQLite.Net PCL.
5. To separate the performance of each platform, you must write a separate interface for each.

Create an interface called I SQLite, for example, and write the following code inside:

using SQLite.Net;
namespace XamarinSqliteSample
{ public interface ISQLite
{
SQLite Connection Get Connection ();
} }

All we have to do is locate the database file and then make the connection between them. By implementing this interface in native projects through Dependency Service, communication between them can be established.

Build a database
After creating an interface for each platform, separating their functions and creating a connection, we can define our database.
In this example, we define and create a database that stores student information. The name of the class that will hold the student information in the database is Student.

using System;
using SQLite.Net.Attributes;

namespace XamarinSqliteSample
{ public class Student
{
[Primary Key, Auto Increment] public int Id {get; set;} public string Name {get; set;} public string Address {get; set;}
public string Phone {get; set;}

public Student ()
{
}
} }

Using this code, we designed and created four columns, id is defined as Primary Key because its values will be unique and non-duplicate. In this example, using this code, the id value is defined as Auto Increment.

Next, for the convenience of work, we create a class as a database and keep the logic and how to access the database and its tables inside the same class. The name of this class, which is a database, is called Student DB.

using System. LINQ;
using SQLite.Net;
using Xamarin. Forms;

namespace XamarinSqliteSample
{
public class Student DB
{
private SQLite Connection _sqlconnection;

public Student DB ()
{
//Getting connection and Creating table
_sqlconnection = DependencyService.Get(). Get Connection ();
_sqlconnection. Create Table ();
}

//Get all students public IEnumerable Get Students ()
{
return (from t in _sqlconnection. Table () select t). To List ();
}

//Get specific student
public Student Get Student (int id)
{
return _sqlconnection. Table (). FirstOrDefault (t => t. Id == id);
}

//Delete specific student
public void Delete Student (int id)
{
_sqlconnection. Delete(id);
}

//Add new student to DB
public void AddStusent (Student student)
{
_sqlconnection. Insert(student);
}
}
}

Two very important points in these codes:

1- In order to be able to access the classes registered in the Student DB interface, we must use the Get Connection () method, which is located in the Dependency Service class.
2- Using the Create Table method, a table called Student is created in the SQLite Connection class . This table is created when it does not already exist.

IOS implementation
The main problem with using SQLite Database is when we want to store real files in the database. To solve or fix this problem, we must take steps.
Both SQLite.Net PCL and SQLite.NET PCL - XamarinIOS Platform packages must be added to the project before adding any feature from the SQLite database to the iOS project. It is possible to add these packages through Nuget.
The main obstacle that needs to be solved when using SQLite is when we want to store the data in the actual database file. This barrier varies from platform to platform.
To implement the ISQLite interface, you need to create a class called SQLite iOS.

using System;
using Xamarin. Forms;
using XamarinSqliteSample. IOS;
using System.IO;

[assembly: Dependency (type of (SQLite iOS))]
namespace XamarinSqliteSample. IOS 6- {
public class SQLite iOS: ISQLite
{
public SQLite.Net.SQLiteConnection Get Connection ()
{
var filename = "Student.db3";
var documents Path = Environment.GetFolderPath(Environment.SpecialFolder. Personal);
var library Path = Path. Combine (documents Path, "..", "Library"); 14- var path = Path. Combine (library Path, filename);

var platform = new SQLite.Net.Platform. XamarinIOS.SQLitePlatformIOS(); var connection = new SQLite.Net.SQLiteConnection(platform, path);

return connection;
}
}
}

The assembly attribute at the top of this code is used to retrieve the Dependency Service class via the Get method, because we want to define this class as Dependency.
Once we have access to the database file storage, we add an object called SQLite Connection and return it to the original PCL project.

Android implementation
The Android implementation is quite similar to the iOS implementation, but the only difference between the Android and iOS implementations is that the database file paths are different. Be sure to install SQLite.Net PCL and SQLite.NET PCL - XamarinAndroid packages through Nuget.
To implement the ISQLite interface, you need to create a class called SQLite Android.

using System;
using System.IO;
using Xamarin. Forms;
using XamarinSqliteSample. Droid;

[assembly: Dependency (type of (SQLite Android))]
namespace XamarinSqliteSample. Droid
{
public class SQLite Android: ISQLite
{
public SQLite.Net.SQLiteConnection Get Connection ()
{
var filename = "Student.db3";
var documents path = Environment.GetFolderPath(Environment.SpecialFolder. Personal);
var path = Path. Combine (documents path, filename);

var platform = new SQLite.Net.Platform. XamarinAndroid.SQLitePlatformAndroid();
var connection = new SQLite.Net.SQLiteConnection(platform, path); 16. return connection;
}
}
}

Windows Phone implementation
You need to spend a little more time and work to implement Windows Phone, because database engines are available on Android and iOS operating systems and are easier to set up.
After you have installed the SQLite database , you need to add the SQLite.NetPCL and SQLite.Net PCL - Windows Phone 8 Platform packages to your project.
To implement the ISQLite interface, you need to create a class called Windows Phone.

The steps for adding support to the Windows Phone project are as follows:

using Xamarin. Forms;
using XamarinSqliteSample.WinPhone;
using System.IO;
using Windows. Storage;

[assembly: Dependency (type of(SQLite_WinPhone))] namespace XamarinSqliteSample.WinPhone
{ public class SQLite_WinPhone: ISQLite
{
public SQLite_WinPhone ()
{
}
public SQLite.Net.SQLiteConnection Get Connection ()
{
var filename = "Student.db3";
var path = Path. Combine (ApplicationData.Current. LocalFolder.Path, filename);

var platform = new SQLite.Net.Platform. WindowsPhone8.SQLitePlatformWP8(); var connection = new SQLite.Net.SQLiteConnection(platform, path); return connection;
}
} }

Xamarin is a programming language based on the C # programming language. With CAM-based programming in xamarin, you can get three different outputs at the same time, outputs for Android applications, IOS applications and Windows applications.

What are push notifications?
Push notifications are notifications that are sent to users by the server without the user request. Push notifications are called push notifications because notifications are sent to users by the server without the user request. Of course, this does not mean that the server can send any relevant or unrelated information to the user, but it does mean that the user first activates the service and makes the relevant settings and notifications from The server side is sent to it automatically before the user requests.
Users can change the settings for push notifications if needed, or even disable them if they wish.
One of the most important features and benefits of push notifications is that no special program is required to receive these notifications and notifications will be sent and received even when the phone screen is off.
Updates are done on smartphones with different Android and IOS operating systems . Developers of these operating systems also use different methods to send notifications. Developers of Android operating system use Google Cloud Mesغير مجاز مي باشدing or Firebase Cloud Mesغير مجاز مي باشدing service to send information to phones with Android operating system. The Apple Push Notification Services API is used to send information to iOS operating systems.

How are push notifications sent?
There are different technologies for sending pressure notifications that each site and company uses different technologies to send pressure notifications on their site.

These technologies include the following:

• Apple Push Notification Service (APNS)
• Google Cloud Mesغير مجاز مي باشدing (GCM)
• Windows Push Notification Services (WNS)
Sending push notifications cannot be done directly. To send notifications, you must make sure that there is a support service, after the user confirms to send push notifications, automatically and before the user requests, the site notifications are sent to the user be.
Launched in 2001, the Mono developers developers organized the platform. Xamarin is an open source platform built on the .NET framework that provides opportunities for development in the Microsoft environment. Following the announcement of Xamarin as an open source platform, it became part of the Xamarin Visual Studio Integrated Development Environment (IDE).
Xamarin can also be used to send push notifications to extended applications. This is usually the same as sending notifications via Google Firebase
The Firebase Cloud Mesغير مجاز مي باشدing Service (FCM) is available for sending mesغير مجاز مي باشدe notifications and more.

How to enable XAMARIN push notifications:
Azure notification hub is commonly used to send notifications to an Android Xamarin app. These notifications are played on all Android devices using the Firebase Cloud Mesغير مجاز مي باشدing feature.
Hub is used to transfer information to Xamarin. Forms applications. Transfer notifications to Xamarin.Forms applications used to target Android and iOS operating systems. To use the best and latest installation methods, it is best to use the ASP.NET Core Web API extension, which sends push notifications and notifications cross-platform.

In this tutorial you will learn the following note:

• Set up Push Notification and Azure Notification Hub services.
• How to setup google notification cloud mesغير مجاز مي باشدing or Firebase Cloud Mesغير مجاز مي باشدing (FCM)
• How to implement push notifications for
Android apps .
• How to implement push notifications for
iOS apps .
• How to send push notifications.
• How to receive and process push notifications.

Basic Requirements:

• Mac computer with Visual Studio installed.
• Install Xamarin and .NET with Visual Studio.
• Ability to run a Xamarin application on both Android and iOS platform.
• Physical device or emulator (capable of running API 26 and above using applications installed on the Google Play service.)

Implementation of Push Notification on Xamarin Android:

1- Go to https://console.firebase.google.com and signup and create a project for your app. (this will be useful for all platforms)
2- In the cloud mesغير مجاز مي باشدing settings, download and add google-services.json to Xamarin.Android project root.
3- Right click on google-services.json in Visual studio and set the buildaction => googleJson
4- Install nuget package => xamarin.firebase.mesغير مجاز مي باشدing for android 60.11
5- Install nuget package => xamarin.googleplayservices.base
6- remove all green-icon android support nuget pacakages (if exist)
7- update all other available nugets
8- Add this Code to your AndroidManifest.xml file inside the application tag.

9- In your MainActivity.cs File, you can add this:

public static string NotificationToken = "";

protected override void OnCreate(Bundle savedInstanceState)
{
try
{
//Register for Notification Channel
FirebaseApp app = FirebaseApp.InitializeApp(Android.App.Application.Context);
AdnroidNotification.CreateNotificationChannel();
//Notification Click Action
if (!string.IsNullOrEmpty(act.Intent.GetStringExtra("ClickAction")))
{
//WRITE YOUR CLICK ACTION HERE
using (service as IDisposable)
{
service.Open(act.Intent.GetStringExtra("ClickAction"));
}
}
}
catch
{

}

base.OnCreate(savedInstanceState);
global::Xamarin.Forms.Forms.Init(this, savedInstanceState);
LoadApplication(new App());

}

10- Create a class in you Xamarin.Android project and add this code:

public class AdnroidNotification
{
public static readonly int NOTIFICATION_ID = 1000;
public static readonly string CHANNEL_ID = "general_notification";
public static readonly string CHANNEL_NAME = "General Notification";
public static void CreateNotificationChannel()
{
if (Build.VERSION.SdkInt < BuildVersionCodes.O) return;
var channel = new NotificationChannel(CHANNEL_ID, CHANNEL_NAME, NotificationImportance.Default) { Description = CHANNEL_NAME };
var notificationManager = (NotificationManager)Notification.Act.GetSystemService(Context.NotificationService);
notificationManager.CreateNotificationChannel(channel);
}
}

[Service]
[IntentFilter(new[] { "com.google.firebase.INSTANCE_ID_EVENT" })]
public class FirebaseRegistrationService : FirebaseInstanceIdService
{
public override void OnTokenRefresh()
{

Mesغير مجاز مي باشدeClickAction = mesغير مجاز مي باشدe.Data["Mesغير مجاز مي باشدeClickAction"];
}
catch
{
}
if (string.IsNullOrWhiteSpace(Mesغير مجاز مي باشدeBody)) return;
ShowNotification(Mesغير مجاز مي باشدeTitle, Mesغير مجاز مي باشدeBody, Mesغير مجاز مي باشدeClickAction, Mesغير مجاز مي باشدeSound);
}
catch (Exception ex)
{
}
}

public void ShowNotification(string Title, string Body, string ClickAction, string Sound)
{
var valuesForActivity = new Bundle();
if (!string.IsNullOrEmpty(ClickAction)) valuesForActivity.PutString("ClickAction", ClickAction);
var intent = new Intent(this, Notification.Act.GetType());

intent.AddFlags(ActivityFlags.ClearTop);
intent.PutExtras(valuesForActivity);
var pendingIntent = PendingIntent.GetActivity(this, 0, intent, PendingIntentFlags.OneShot);

var notificationBuilder = new NotificationCompat.Builder(this)
.SetSmallIcon(ApplicationInfo.Icon)
.SetContentTitle(Title)
.SetContentText(Body)
.SetContentIntent(pendingIntent)
.SetSound(string.IsNullOrEmpty(Sound) ? null : RingtoneManager.GetDefaultUri(RingtoneType.Notification))
.SetChannelId(AdnroidNotification.CHANNEL_ID)
.SetStyle(new NotificationCompat.BigTextStyle().BigText(Body))
.SetAutoCancel(true);

var notificationManager = NotificationManager.FromContext(this);
notificationManager.Notify(0, notificationBuilder.Build());
}

}

Implementation of Push Notification on Xamarin iOS:

1- Go to https://console.firebase.google.com and click on the same project you created on Android section.
2- add GoogleService-Info.plist to your iOS project root
3- right click on GoogleService-Info.plist on Visual studio, and in properties, set the buildaction => bundleresource
4- Install nuget package => Xamarin.Firebase.iOS.CloudMesغير مجاز مي باشدing
5- Install nuget package => xamarin.googleplayservices.base
6- remove all green-icon android support nuget pacakages (if exist)
7- update all other available nugets
8- Apple developer account -> in Certificates, IDs & Profiles -> Keys -> create APN key -> upload it in firebase console.
9- Apple developer account -> Certificates -> add certificate for notification for this specific app project.
10- In you Xamarin.iOS project your AppDelegate.cs file will look like this:

public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
var del = new AppDelegate_Notification();
Firebase.Core.App.Configure();
// Register your app for remote notifications.
if (UIDevice.CurrentDevice.CheckSystemVersion(10, 0))
{
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.Current.Delegate = del;

var authOptions = UNAuthorizationOptions.Alert | UNAuthorizationOptions.Badge | UNAuthorizationOptions.Sound;
UNUserNotificationCenter.Current.RequestAuthorization(authOptions, (granted, error) => {
Console.WriteLine(granted);
});
}
else
{
// iOS 9 or before
var allNotificationTypes = UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound;
var settings = UIUserNotificationSettings.GetSettingsForTypes(allNotificationTypes, null);
UIApplication.SharedApplication.RegisterUserNotificationSettings(settings);
}

UIApplication.SharedApplication.RegisterForRemoteNotifications();
Mesغير مجاز مي باشدing.SharedInstance.Delegate = del;
//Mesغير مجاز مي باشدing.SharedInstance.ShouldEstablishDirectChannel = true;

global::Xamarin.Forms.Forms.Init();
LoadApplication(new App());
var result = base.FinishedLaunching(app, options);
return result;
}

11- Create a class in you Xamarin.iOS project and add this code:

public class AppDelegate_Notification : global::Xamarin.Forms.Platform.iOS.FormsApplicationDelegate, UserNotifications.IUNUserNotificationCenterDelegate, Firebase.CloudMesغير مجاز مي باشدing.IMesغير مجاز مي باشدingDelegate
{
// Receive displayed notifications for iOS 10 devices.
// Handle incoming notification mesغير مجاز مي باشدes while app is in the foreground.
[Export("userNotificationCenter:willPresentNotification:withCompletionHandler:")]
public void WillPresentNotification(UNUserNotificationCenter center, UNNotification notification, Action completionHandler)
{
var userInfo = notification.Request.Content.UserInfo;

// With swizzling disabled you must let Mesغير مجاز مي باشدing know about the mesغير مجاز مي باشدe, for Analytics
//Mesغير مجاز مي باشدing.SharedInstance.AppDidReceiveMesغير مجاز مي باشدe (userInfo);

// Change this to your preferred presentation option
completionHandler(UNNotificationPresentationOptions.Alert);
}

// Handle notification mesغير مجاز مي باشدes after display notification is tapped by the user.
[Export("userNotificationCenter:didReceiveNotificationResponse:withCompletionHandler:")]
public void DidReceiveNotificationResponse(UNUserNotificationCenter center, UNNotificationResponse response, Action completionHandler)
{
var userInfo = response.Notification.Request.Content.UserInfo;
var Aps = (NSDictionary)userInfo["aps"];
var Alert = (NSDictionary)Aps["alert"];
var Title = (NSString)Alert["title"];
var Body = (NSString)Alert["body"];
var ClickAction = (NSString)Aps["category"];
var Sound = (NSString)Aps["sound"];
{

using (service as IDisposable)
{
service.Open(ClickAction);
}
}
completionHandler();
}

public override void RegisteredForRemoteNotifications(UIApplication application, NSData deviceToken)
{
Mesغير مجاز مي باشدing.SharedInstance.ApnsToken = deviceToken;
}

}

[Export("mesغير مجاز مي باشدing:didReceiveMesغير مجاز مي باشدe:")]
public void DidReceiveMesغير مجاز مي باشدe(Mesغير مجاز مي باشدing mesغير مجاز مي باشدing, RemoteMesغير مجاز مي باشدe remoteMesغير مجاز مي باشدe)
{
}

public class UserInfoEventArgs : EventArgs
{
public NSDictionary UserInfo { get; private set; }
public Mesغير مجاز مي باشدeType Mesغير مجاز مي باشدeType { get; private set; }

public UserInfoEventArgs(NSDictionary userInfo, Mesغير مجاز مي باشدeType mesغير مجاز مي باشدeType)
{
UserInfo = userInfo;
Mesغير مجاز مي باشدeType = mesغير مجاز مي باشدeType;
}
}

public enum Mesغير مجاز مي باشدeType
{
Notification,
Data
}
}

Note:
IOS emulator cannot support remote notifications, it is better to use a physical device to support them.
Without the need for previous experience or technical knowledge, by mentioned and following steps of this training and observing its principles, you can get acquainted with and benefit from the following aspects.
• Xamarin and
Xamarin forms
• Google Firebase console
• Microsoft Azure and how to send push notifications through Azure Notification Hubs.
• Apple Developer Portal
• ASP.NET Core and Web API

How to set up Push Notification and Azure Notification Hub services (For UWP platform)
Azure notification hub hub is usually used to send notifications to a Xamarin Android application. These notifications are broadcasted over all the android devices using the Firebase Cloud Mesغير مجاز مي باشدing feature.

To send push notifications to follow the below-given steps:

1- You have to create a Firebase project and have to enable the
Firebase Firebase Cloud Mesغير مجاز مي باشدing feature.
2- Now create a notification hub.
3- Introduce the Xamarin. Android app and develop a connection with the notification hub.
4- Now send test notifications from the Azure portal.
ENABLING FIREBASE CLOUD NOTIFICATION:
1- Sign in to Firebase console and create a new project.
2- Add Firebase to your android application

3- Declare a name for the application, register your app, download googleservices.json.
4- Select project settings, make a selection on the Cloud Mesغير مجاز مي باشدing option on the top, and save the generated server key.

DEVELOPING A MICROSOFT NOTIFICATION HUB:

1. Enter the Azure portal
2. Select the notification center in the mobile section.
3. In the generated page, select Add, enter a name, select a value for the location and a group of available resources.
4. Select the provided access policies.

Establish a connection between XAMARIN ANDROID APP and Hub Alert:

1. Create a VS project.
2. Select the available File option, then click on the project.
3. In your project, expand Visual C #, click on Android and select Android App (Xamarin).
4. Now after that, announce a name for the project and select the location, and finally select ok to continue your work.

You will be notified that you must have an Azure account, a Visual Studio with Xamarin on Windows, or a Visual Studio for Mac on OS X and an active Google Account.

Some of the main features of Xamarin are:

• Use of a single language: Xamarin • only uses C# as a native tool for the development of mobile-based applications. Unlike other interpreters, it is a go-to precision for building high-performance applications.
• The .NET framework comes across many features like LINQ, Asynchronous programming, Lambdas, and, based on C#, can be used as a tool for better programming aspects.
• Xamarin supports access to the latest APIs to acquire its capabilities in applications such as in ARKit on IOS or Android Multi-Window.

Links are very important in optimizing a website , for example, internal links make it easier and better for Google to realize the structure of a website, and through this type of link, website owners can specify the priority of websites and give more links to the pages which are more valuable. The use of backlinks also causes a website to be more reputable, it also has a great impact on the website ranking in the search engine results page.

As mentioned so far, there are two types of links, which are internal links and external links, the two of which are different from each other, which we will explain each one separately.

What is Link Building?
Link Building is the process of creating a link which may cause the connection of two different pages of a website or the connection of two different websites together. These two types of links have a great impact on optimizing a website and search engines if the links are valuable and relevant to the website, Google will consider this as a positive point.

Internal links, or in other words links that connect the internal pages of a domain to each other, have related topics. Depending on the number of links on a website, Google receives signals that the site is of good quality. This is also true for external links, but the important point is that these links must be created naturally and if you use methods which are contrary to the rules of SEO in creating links, not only the website will rank lower in the search results page, but also it will be penalized in some cases.

How do search engines use links?
Search engines use links to rank a website as well as to discover new pages. When search engines visit different pages of a website, they examine and extract the content of the pages and decide based on its content. Each link acts like a vote, however, the more quality websites which link to you, the more valuable these votes will be, and the more impact they will have on the ranking.

As you know, Google offers different algorithms, which are becoming more and more powerful in determining the quality of websites. One of these algorithms is the Google PageRank algorithm , which was created to rank web pages and websites. The score that this algorithm gives is between zero and ten, which is measured through the inbound links of a website. In this way, if there is more inbound links to a website , the value of it will be more according to Google.

In other words, each inbound link to a website counts as a vote to increase the ranking of that website, and another point is that the more value and credibility of that linking website, the more valuable that vote will be. This algorithm has become an important tool for Google, which is a great way to determine the quality of a page that Google uses. Simply put, when a website links to the content of another site, it actually means that the site is a good and trusted one to which it links. There are different links building techniques that SEO experts use to build links to get high rankings on the search results page. Of course, some sites try to use too many links to attract more attention from Google, in which case it will cause a negative ranking for the website, and it may be penalized.

A number of types of internal links:
Contextual, Video Links, Navigational, PhotoLink, JavaScript Links

A number of types of external links:
Editorial backlinks, Guest blogging backlinks, Backlinks in business profiles, Backlinks from webinars, Free-tool backlinks, Acknowledgment backlinks, Guest post bio backlinks, Badge backlinks, Comment backlinks

What effect does link building have on businesses?
In general, link building increases SEO ranking , but it also has a great impact on businesses, which are mentioned below:

-Becoming a reputable brand:
Good and principled link building causes your brand to be more noticed and through links to other sites to show users that you have enough expertise in the field of your business, so your brand will be seen more and more overtime.

-Improve your trading performance:
When a reputable website links to your website, its customers will be attracted to your site over time and the website traffic will increase, which will have a significant impact on your business.

-The ability to communicate more with other fields of work:
Once you have received a lot of links in your field of work, it will be possible for you to connect with other businesses and through this you can promote your business.

The tricks you can use to persuade other sites to link to your site pages?
-Improve the quality of the site content, so that other websites, will decide to link to your site after viewing it.

A site may be penalized by the search engine without having control over the negative SEO and knowing the ways of dealing with it, even after a period of time and successive penalties the website owner may be forced to close the website, so as a person who cares about website optimization , you need to get acquainted with this type of SEO and know the ways to deal with it.

Negative SEO is a set of actions taken by a site's competitors on competing sites with the aim of reducing their website's ranking in search engine results. Simply put, it is a kind of Black Hat SEO, the difference between them is that in Black Hat SEO site owners implement the actions that are against the rules of SEO on their websites to increase the ranking of them, but in negative SEO they implement this set of activities on the competitor sites to decrease their ranking and attract competitors’ users to their own websites.
