Recently I started making websites on WordPress. I work with some people who have a certain obsession with the results on Google Speed. So I went to research more about this (the page load speed), and I came across a large community that deals with this. I saw many ads that promise a 100 score, and they usually put their pages as proof. But I noticed that these pages are just landing pages with nothing too complex. No plugins for forms or contact. Is this something legit or is it a scam? I ran Google Speed on very famous pages here and none had great performance in load speed. In my case what is weighing the most are the Google tags.
