In the world of web development, client-side rendering (CSR) and server-side rendering (SSR) are two popular methods of rendering web pages. While both methods have their own advantages and disadvantages, when it comes to SEO, server-side rendering is the preferred method.
Google’s search engine algorithm gives priority to websites that load quickly and have well-organized HTML code. With server-side rendering, the server provides fully rendered HTML code to the browser, which makes it easy for search engine bots to crawl and index. This means that websites that use SSR tend to rank higher in search engine results pages (SERPs).
On the other hand, with client-side rendering, the initial HTML page that’s sent to the browser is barebones, and the content is loaded dynamically using JavaScript. This can result in slower loading times, which can negatively affect SEO. Additionally, since CSR relies heavily on JavaScript, it can result in poorly organized HTML code, which can be challenging for search engine bots to crawl and index.
Another factor that can impact SEO is the time it takes for a website to load. With server-side rendering, the website loads quickly, as the fully rendered HTML code is sent directly to the browser. In contrast, with client-side rendering, the initial page load can be slower, as the browser needs to download the barebones HTML and then dynamically load the content using JavaScript. This delay in loading time can negatively affect the SEO score of a website, as Google’s algorithm prioritizes fast-loading websites.
