Page Speed Insights

When Google tells you with Search Console that one of your pages is slow to download, you can connect to the Page Speed Insights toolone of the SEO tools to get information about the download speed of this page and the reasons that may slow it down.

This speed is a major criterion according to Google which indicates to place at the top of the results the fastest loading pages (among those whose content corresponds to the keywords used). Why this choice?

The search engine constantly analyzes the behavior of Internet users performing searches. Its position as market leader means that it has the largest source of information on this subject. He realized that every second they waited, more and more users lost patience and went to do another search rather than wait for a page to be displayed.

If you don’t want to lose visitors to your site, it is important to check the loading time of each of your pages. Page Speed Insights shows you a score out of 100 after calculating the loading time of your page. It also tells you in detail what can slow it down:

  • Images too heavy to load
  • Non-optimized Javascript or CSS files
  • Links waiting to load content external to your site
  • Slowness of the server that hosts your pages
