Server-Side vs Client-Side Rendering and Changing SEO Practices

It often seems like patterns in Web creation overturn conventional wisdom every six weeks. Only a few things have remained constant throughout, and one of them is that good websites need to show up well in search results. Search engines are the Web’s front pages, and their goal has always been to list high-quality websites that are important to a search word.There is no better way than to make it follow these requirements to drive traffic to your website.

It sounds simple, but Search Engine Optimization (SEO) is a career that works full time. Over the years, search engines have altered their tactics, the things they calculate, and their other hidden formulas, and we’ve modified the way we create websites on top of all that.

As high as ever, the need for SEO is, and SEO experts are used to the rapid pace of change. Nevertheless, some modifications are major enough that we have to re-examine how search engines do what they do and adapt SEO best practises to match the actual reality.

Search engines have been analysing websites since their invention by reading the HTML created by their servers. However, the word Server-Side Rendering (SSR) is fairly recent. We only named it “rendering” until the last few years, because it was the only way Web pages were served.

The Web has developed into a rich forum for applications. Web pages are now supposed to be as interactive and dynamic as any other graphical gui, and by inventing ways to write HTML with JavaScript on the fly, we have accomplished that. With these more versatile client-side rendering (CSR) techniques, much of the modern Web is constructed.

They have proven to be the best way to create dynamic websites that are efficient and scalable.

Crawler bots for search engines are not full-fledged Web browsers, however. They have to navigate across a huge web of content quickly. These bots did not run JavaScript for years and did not support CSR; the Googlebot would actually not see it if your website used CSR to view its content and features. Since this has been the case for so long, SSR is well known to modern search engine crawlers/bots as the content rendering tool ideally suited to ensuring HTML content is readily accessible. We would presume at this stage that SSR information is well understood from a strategy and implementation perspective. It’s a fundamental feature of the Web site.

The end-user experience benefits from CSR, but it poses a range of concerns regarding maintaining consistent ranking and placement criteria within the results of the search engine. Most major websites, and most eCommerce sites in particular, have solved this by making a web page’s “indexable” content on the server and then moving to CSR to handle the page once it has been loaded. We also know that SSR will render a site slower when not performed correctly. Speed and efficiency are equally, if not more, critical today to ensure ranking/placement for search engines. If a search engine could crawl CSR-generated websites, making the entire app with CSR would be simpler and quicker, as you’re going to need it for the fancy bits. The biggest search engines are beginning to support CSR in their crawler bots right now, and finally, despite doing no SSR at all, we can see many early adopters with very high result rankings.

However, as a crucial factor for customer acquisition and revenue generation, companies have come to rely on SEO and search engine marketing (SEM). Anything that challenges the tactics that have worked effectively over the past decade has the potential to have a major effect on the continued success of an organisation.It is a big question to ask merchants to make the transition to Progressive Mobile Apps (PWAs) and Web storefronts that are heavily reliant on CSR versus SSR.

With PWA Studio, we strive to create what we see as the Web’s future (where SSR dependency is no longer a difficult requirement) while also accommodating the current needs and concerns of the merchant.
