How Google Pagespeed works
> In July, the SEO ranking algorithm was updated to include page speed as a ranking factor for both mobile pages <i></i>and ads<i></i>.<p>What's one supposed to do when PageSpeed only points to Google's own asset delivery services as being "the" big problems which cause a lower score?<p>- "serve images in next gen formats" - complains about images served from tpc.googlesyndication.com<p>- "efficiently encode images" - same as above<p>- "reduce javascript execution time" - cdn.ampproject.org; securepubads.g.doubleclick.net; www.googletagservices.com<p>.. ?<p>I can easily get rid of those issues, "simply" by not showing any ads. The site will then be really fast, and... I'll get the ability to display ads again?!<p>Shame the ad-related revenue will be 0, which isn't unfortunately a good thing for the site.<p>Why is Google themselves not doing things "right" in order to ensure a speedy execution?<p>A while back, one of the reasons for a low score was that the GPT.js code (required to show ads) had a short expiration time. Dammit. How am I supposed to fix that, Google?
