What is Rendering?


Rendering is interpreting the HTML, CSS, and java script on the page to build the visual representation of exactly what you see in your web browser. A web browser renders code into a web page. The rendering of HTML code takes computer processing power. If your pages rely on java script to render the page’s content, it takes an enormous amount of processing. While Google can crawl and render java script pages, the JS rendering will go to a prioritization queue. Depending on the importance of the page, it could take a while to get to it. If you have a really large website that requires java script to render the content on the pages, it can take a long time to get new or updated pages indexed. It’s recommended to serve content and links in HTML rather than java script if possible.
