How do I apply SEO to the ReactJS application?

Let's look at a simple example of adding SEO to a React component using the react-helmet library. In this example, we'll create a basic React component and set the page title and meta description dynamically. Install the react-helmet library:

  1.  npm install react-helmet
    
  2. Make a React component and use react-helmet to set the title and meta description:

     // components/MyComponent.js
     import React from 'react';
     import { Helmet } from 'react-helmet';
    
     const MyComponent = () => {
       return (
         <div>
           <Helmet>
             <title>My Page Title</title>
             <meta name="description" content="This is a description of my page." />
           </Helmet>
           <h1>Welcome to My Page</h1>
           <p>This is the content of my page.</p>
         </div>
       );
     };
    
     export default MyComponent;
    
  3. Add this component to your app. For instance, in your main App.js file:

     // App.js
     import React from 'react';
     import MyComponent from './components/MyComponent';
    
     const App = () => {
       return (
         <div>
           <MyComponent />
         </div>
       );
     };
    
     export default App;
    
  4. When someone visits this page, the created HTML will have the title and meta description set automatically. Search engines will see this information when they look at your site.

     <!-- Rendered HTML -->
     <html lang="en">
       <head>
         <meta charset="utf-8" />
         <meta name="viewport" content="width=device-width, initial-scale=1" />
         <title>My Page Title</title>
         <meta name="description" content="This is a description of my page." />
         <!-- Other meta tags and head elements may be present based on your configuration -->
       </head>
       <body>
         <!-- Your component content -->
         <div>
           <h1>Welcome to My Page</h1>
           <p>This is the content of my page.</p>
         </div>
       </body>
     </html>
    

This example shows a simple way to use react-helmet for adding SEO-related details to your React components. Make sure to change the title and meta description for each page in your app based on its content.
