But React or any other framework has a limited understanding of SEO(search engine optimization). So, Today we will discuss the solutions we can have to gain SEO access.
Let's start with Single Page Optimization to understand the challenges with SEO in React Websites.
A single-page application is an app that doesn't demand to reload the page during its use and works within a browser. Think of the apps you use daily like Facebook, Google Maps, Gmail, Twitter, Google Drive, or even GitHub. These all are examples of a SPA.
Here, content is served on a single HTML page. Rather than sending a new request to the server each time and then getting a whole new page with new content, the client-side of a single-page web app only requests for the updated data.
These apps cache data in local storage that means they will load even faster next time again.
Search Engine Optimization (SEO) is how Google performs basically. You type something into Google and then Google gives you lots of results. Those results are web pages.
According to Backlinko, 75% of all users go to the top three websites in search engine results and beyond get 0.78% of clicks.
To determine a website's ranking, search engines use web crawlers that may be known as Google bots. That's why crawlers should understand the website content and that's where the problem starts.
In this way, google bots arise issues when it comes to searching from website content on the web pages.
You can make React SEO friendly by creating an isomorphic React app or by using prerendering.
You can run the React app and capture the rendered HTML file. Then, It can be served to everyone who requests the site (including Googlebot).
But This is a Time-Consuming App. And we have alternative frameworks - Gatsby and Nextjs that helps in solving SEO issues.
Server-side rendering with Next.js
The Next.js rendering algorithm seems as follows:
Making website SEO Friendly with GatsbyJS
Here we have two phases -
Generating a static website during the build and processing requests during runtime.
The build time process seems as follows:
Request processing during runtime happens like this:
The idea of prerendering is to preload all HTML elements on the page and cache all SPA pages on the server with the help of Headless Chrome. We can do this is using a prerendering service like prerender.io. A prerendering service intercepts all requests to your website and, with the help of a user agent, defines whether a bot or a user is viewing the website.
If the viewer is a bot, it gets the cached HTML version of the page. If it’s a user, the single-page app loads normally.
Prerendering has a smaller server payload related to server-side rendering. But on the other hand, most prerendering services are paid and work poorly with dynamically changing content.
Challenges with SEO shouldn’t be a reason for you to avoid using the React library. Rather, you can go for the above-mentioned solutions to meet this issue. Moreover, search engine crawlers are getting smarter every year, so in the future, SEO optimization may no longer be a pitfall of using React.
Have a happy reading!
