Yoast scores. RankMath scores. Same garbage, different plugin.
Here's the uncomfortable truth: the document you're trying to rank is the claim - not the evidence. You don't rank because you hit a green light on some checklist. You rank because other sites vouch for you.
Everyone's busy optimizing HTML like Google reads it line by line. Newsflash: Google assumes your code is broken. It doesn't execute it. It doesn't care about your PageSpeed score or your "clean" markup. The SEO tribes love their ideology - tech SEOs worship Core Web Vitals, content SEOs preach "quality content" - but nobody wants to hear the actual answer.
Third-party relevance. PageRank. Always has been.
The starter guide spells it out. Nobody reads it. They'd rather chase a green dot and wonder why traffic flatlines.
