Prerender
Prerender
Get higher rankings by serving crawlers a static HTML version of your Javascript website, without compromising your customers’ experience. Prerender® is a SaaS platform that makes your JavaScript website SEO-friendly. Before your customer can find your website on search engines like Google, it first has to be crawled and indexed by one of their web crawlers, such as Googlebot. They do this by reading and cataloging a stripped-down, HTML version of your website with the visual and interactive elements taken away. This normally isn’t an issue if your website is built in static HTML, and typically takes just a few days. If your website is made in a JavaScript framework, it’s a different story. While Google can crawl websites built in JavaScript, it’s much harder for them to do. It can easily take weeks before your JavaScript website can be indexed and found in the search results. Google will see all of your content and links, and get your website in front of your customers in no-time.Starting Price: $90 per month -
