JavaScript SEO

A specialized SEO service focused on improving the visibility of JavaScript-based sites.

Many websites use JavaScript frameworks such as React, Vue.js and Angular. Despite their advanced functionality, these sites may not be easily indexed by search engines, leading to lowered positions in search results. With JavaScript SEO, you can eliminate the obstacles to building visibility and reaching customers.

We will help you solve the visibility problems of your JavaScript-based site.

JavaScript is one of the most popular programming languages and a powerful tool in creating modern websites. However, without proper optimization, it can become an obstacle between your site and its visibility on Google.

JavaScript-based rendering and indexing optimization

Rendering is the process of transforming the code of a page (e.g. HTML, CSS, JavaScript) into what you see on the screen. With indexing, search engines can quickly find and show relevant results. Current JavaScript frameworks (such as React, Angular, Vue, NextJS or Svelte) have solutions that are intended to be SEO-friendly. That's why we first make sure that they actually are. If not, we solve these problems by optimizing and using the frameworks' internal mechanisms.

Implementing Server Side Rendering

Implementing SSR (Server Side Rendering) can significantly improve the indexability of your site and increase its loading speed. SRR generates the entire HTML code of a page on the server before sending it to the browser. Unlike CSR (Client-Side Rendering), where the browser takes minimal HTML and renders the page using JavaScript, SSR generates a complete page on the server that the browser can read and display immediately.

Regular optimization of a JavaScript-based site

Even if we implement SSR, it is still worth optimizing the site. Most properly thought-out JS frameworks (the most popular are Vue, React or Angular) use so-called Hydration, which synchronizes the code generated on the server and makes it interactive again on the user side. Hydration, which is like a bridge between SSR and CSR, is an element that in practice often causes delays, such as the INP parameter from Core Web Vitals.

JS vs. SEO

The impact of JavaScript on SEO

Despite the fact that Google officially handles JavaScript interpretation, practice shows that this is almost always fraught with more or less problems. This is where the implementation of SSR comes to the rescue.

Server-Side Rendering solves rendering problems that result from using only a dynamic approach. JavaScript can affect page load time, which is an SEO ranking factor. Google processes JavaScript through scanning, rendering and indexing. The search engine may need more time to render JavaScript pages and fully index them. JavaScript-based pages often use dynamic content that can change without reloading the entire page. Problems arise, for example, when the content is not rendered (turning code into a screen view). Improperly created or implemented dynamic URLs also cause indexing problems.

How long does it take to optimize JavaScript SEO?

Typically, code analysis and rendering in the case of JavaScript is more time-consuming than in the classical approach, where the code is the same in the page source and is not dynamically processed. In this case, optimization may take longer, but this is not a rule.

It is worth noting that a well implemented and used JS framework from the beginning can be Google-friendly. Then all we need to do is check (and possibly optimize) certain elements. Therefore, it is difficult to say definitively how long the optimization will take, without full knowledge of the site. However, we can confirm that in most cases our JS SEO activities are fully completed within 1-2 months of cooperation.
