Never worry about your web pages being indexed again! Whether you have 100 or 100,000,000 URLs, we solve JavaScript SEO issues without compromising your UX.
Prerender currently serves 2.7 billion web pages to crawlers.
Trusted by 65K developers and marketers across the globe.
On average, it takes 0.05 seconds to load a page with Prerender, as opposed to 5.2 seconds without. This means you can onboard millions of URLs with zero friction—and increase your crawl budget.
Prerender serves 100% cached versions of your web pages to search engine bots that have problems executing JavaScript, so you can save time, money, or resources, and reap technical SEO benefits.
Low page speed times can harm your rankings and Core Web Vital (CWV) scores. Prerender eliminates dynamic issues by generating and storing a static version of every web page and serving them to the search crawlers.
Google needs more resources to crawl JS, and oftentimes, it doesn’t render the entire page of content either. We ensure content and links are fully rendered before the crawl, and avoid using crawl budget unnecessarily.
If Google can’t “read” what’s on your page, it won’t index it. Prerender will ensure your pages are prioritized and indexed fast to help boost SEO and rankings. Now you can properly compete with other static HTML sites.
“Before using Prerender, our site had challenges with crawling, and our pages were largely not indexed due to the site being a single-page app using AngularJS.
Most of the options we looked at required an extensive amount of work, which also translated to very high costs. Prerender provided an easy-to-use and effective solution to the problem. Within days of integrating with Prerender®, we immediately saw tens of thousands of our pages being crawled and indexed by Google. Our organic traffic naturally saw a very steady increase over the next few months. Prerender’s support was great and responsive in the rare instances that we needed it.”

How it Works
JavaScript SEO is hard—here’s how we make it easy.
Googlebot and other search engine spiders have a “crawl budget” that’s quickly used up on complex sites. Prerender’s servers are built for rendering JavaScript at scale, so we produce static HTML pages that are ready to download and parse.
You’ll never have to worry about getting your pages indexed again. If a crawler tries to access a page that isn’t cached, Prerender renders it quickly (without interrupting the process) and caches it afterward. *For greater speed, you can customize your plan with shorter cache freshness or set up the API to cache specific URLs.
Most websites use single-page web applications (SPAs) built in JavaScript. These are great for creating interactive web elements and boosting user experience, but more elements can inhibit SEO. Prerender turns your SPAs into easy-to-read HTML.
Unlock missed opportunities and reach your full SEO potential. When more web pages are crawled, it’s easier to index more of your site and boost SEO performance. Get started with 1,000 URLs free.
Prerender pricing plans are structured in a way that you only pay for the renders you need.

When you click on a website, your browser sends a request to the site’s server to retrieve (fetch) the necessary files (like HTML, CSS, JavaScript, images, etc.). This is used to build the final visual representation of the page (rendering), and it takes place every time you navigate to a page. Now, to speed up the process, we can render the page ahead of time. How, you might ask? We send a pre-rendered static HTML version of the page to the client, providing a faster and more seamless experience to the user or search engine.
We use a technique called dynamic rendering, which can be considered an advanced version of prerendering. Prerender fetches all the necessary resources to build your pages and caches a pre-rendered version of them.
When a new request is sent to your page, Prerender’s middleware will determine whether it’s a search bot or a human user asking for your page: if it’s a search crawler like Googlebot, it’ll send the cached version to make it easier for search engines to crawl and index its content. If it’s a human user, they will get redirected through your normal server routes solving all JavaScript-related SEO issues and allowing you to provide an immersive, JavaScript-rich experience to customers. Learn the full details of Prerender’s process.
