A few years ago, web development was done using HTML and CSS as the front-end and PHP. It was the easiest way to create a website, it still is, but the popularity of developers using HTML and CSS is gradually decreasing. By 2021, the need for intuitive and dynamic web apps led to the dawn of JavaScript. Almost all websites you visit are relying on JavaScript. Not only websites but social media applications like Twitter, Facebook, Instagram, YouTube, Netflix— all use JavaScript. And the adoption of Javascript among developers is overgrowing. This is why having a certification under any react js course becomes helpful.

React is a JavaScript library, commonly referred to as React.js®, which is developed to write Single Page Applications (SPAs) and is increasingly becoming popular among large tech giants such as Google, Twitter, Facebook, and many others. It enables the building of responsive, fast, and animation-rich web applications that can offer a smooth and rich user experience. Google can render it and other JavaScript frameworks, and it is used to create full-fledged websites and mobile applications. Web applications that are developed using React.js® possess limited capabilities for SEO. Search Engine Optimization or SEO is the essential tool that allows Google to determine the rank of websites for queries entered in the search engine. Proper training of these concepts can easily be realised if enrolled for a react js course. Developers use React to make the web apps SEO-friendly, so Google doesn’t have to use JavaScript to render the content. They are achieving this by using Server-Side Rendering (SSR). By implementing this, the visitors can view the content without waiting for React to run first, which means that Google doesn’t need to run JavaScript to read the page’s content.

When building a Single page application (SPA), developers can use any JavaScript frameworks, Angular, React, and Vue. But react is usually developers first choice because of its component-based architecture, reusability, and the ability to divide the extensive application into smaller fragments. In 2019, React was named as the most popular framework by the State of JavaScript survey. It is the best choice to build an SEO-friendly website.

Here are some of the reasons which show the importance of React.JS® In Technical SEO In 2021: –

1. Flexibility

React maximizes and understands the overall performance of the web application as it is very flexible. By flexibility, we mean the library’s innate modularity. It is necessary for technical SEO as it is relatively easy to integrate with other third-party libraries and MVC frameworks. React’s component-based architecture allows building front-end components as custom components. Thus, allowing overall development process optimization and its compatibility with different languages and frameworks enable the developers to incorporate various resources to improve the performance and experience of visitors on websites by adding functionalities and dictating the ways to create reusable components. An experienced developer knows the importance of React in technical SEO as working with it is a delightful experience as it allows reusability of code and delivers clean and modular code. As a result, the flexibility in React makes the code easy to maintain and scale.

2. Easy To Learn

It is relatively easy to learn. Learning React is easier to understand than JavaScript, and it doesn’t burden the learner but aims to make the developer’s choice of learning easier by shortening the equivalent list. Thus, React has a steep learning curve, and developers are getting more inclined to use React to build their projects.

3. Fast Rendering

The faster the page loads, the better is the chance that the visitors don’t leave your website and use the service or product you offer. Fast rendering is significant for operating a business online and using React.js® allows SEO by reducing load times and providing brilliant performance. But ‘How does fast rendering happen?’ The prime reason for the fast rendering in React web apps is React’s Virtual DOM. It serves as a layer between the look of the page and the process. When the developers make new changes in their web application, it gets reflected in Virtual DOM, showing how those changes will look in the web

application. The advantage here is that developers’ changes won’t affect the other components of the web application. Thus, the entire process is more manageable and won’t take loads of time.

4. Strong Community

If a developer gets stuck somewhere while using React, they can go on stack flow and get their answer, as there are over 160K questions tagged under React.js and at least one acceptable solution. Not only does React.js have a strong community, but there is a full-time development team working day and night to make React.js better than it is today.

5. SEO-friendly

The most effective way to increase engagement on your web app is to ensure that your web app is crawlable by search engines. React can be used to create web apps optimized for search engines, thus allowing user engagement. While React, using JavaScript to load pages, is an added advantage, markups are usually loaded dynamically by client-side rendering and are not SEO-friendly or favourable. Therefore, it requires knowledge of technologies like React.js® and its cousins, which can help set up server-side rendering while developing. It is easier for Google to crawl a web app that uses server-side rendering. It is essential in SEO, as it ensures appropriate indexing of websites and improves the outcome.

The snowballing trend of 2021 is front-end web development using React. There is rock-solid evidence of React.js® to remain popular in the coming year of web development as it is in 2021. Nowadays, huge tech giants, entrepreneurs and CEOs are looking for ways to make their websites popular and are thinking of the SEO friendliness of their application before development. If you are mulling over the benefits, then it might be just the right option for you to enrol in a react js course.

It is essential in technical SEO is increasing, evolving, and continuously improving as it allows easy optimization of web apps and makes them SEO-friendly. Since its release, the developers have chosen React for many reasons, such as assertive community support.

React allows building simple interactive user interfaces and component-centric applications. Not only the front-end but it can also be paired with technologies to serve as a backend. This way, it serves as an essential tool in technical SEO and its easy integration and development of web and mobile apps, and even VR app development
