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.

HTMeLd
Gammadyne Corporation
HTMeLd accelerates your website by eliminating references to external files. It scans your HTML pages to determine what images, style sheets, and scripts that each page depends on. Then it loads those resources and embeds them directly into the page. When a visitor downloads the page, their browser will not need to make additional downloads, the page will display almost instantly. This also improves your Google "Page Experience" score, and therefore your Google rank. There is no easier way to gain competitive advantage in Google search results. We recommend installing the free trial, and performing a before and after test using Google's PageSpeed Insights. Look past the "Discover what your real users are experiencing" section as this is data accumulated for the last month from Chrome users, and will not improve instantly. In the "Diagnose performance issues" section, you should see a large improvement with all speed metrics.Starting Price: $30/month/user -
