While that can seem obvious and a good answer, I disagree strongly, my scores are really good, so I doubt it. Plus, massive sites fail web vitals, some are news sites yet cover all categories, for example, and seem to be fine over niche websites dedicated to that topic with real articles and, information, research.
my tffb from a site like [
speedvitals.com...] has me at 93 to 95% in almost all locations given I use full caching edge with Cloudflare, dedicated server, custom stack, optimized MariaDB server, PHP-fpm, nginx, more than any usual person would do with plugins on a WordPress site, optimizing on a backend is the key, along with correct CDN usage and obvious code, lazyloading smartly, image optimization.
also, all the spammy websites, like I keep mentioning have the worse web scores and fail webvitals yet are moving up and taking in some cases top spot. also, they have adsense x 100 ads on each page, literally every 2nd paragraph, it's disgusting. so I think, in my personal opinion it is not an overload of adsense issue, even though I do not even use it.
I wish it was a speed issue, things like this are an easy fix. I spent all Saturday on paid tools like semrush going over things. Honestly, they hardly got any suggestions for my articles since I pass most of their checks, it's like a shrug, small things to improve, more for getting that like 10% extra traffic in their eyes, which of course, may not even work, but, the articles health, layout, words, correct usage of titles, sub-titles, keywords, other content suggestions is high quality already.
I use Grammarly pro for spell checking and plagiarism check, and occasionally run articles on other tools to check once a month or so. I am just waiting now, and I cannot see how I am pinged unless Google has royally screwed it, or they are indexing the scrapers before mine and then penalizing me for spam, if that is true is google screwing it again, like I said before half of them use the images from my article, yet think they are original? wow if so hah.
I will also mention that those manual copycats are taking more of my articles and re-posting on Saturday as well, getting the top spot or top 5 at least, where mine have disappeared from 1 to 5. one site copies my entire text from top to bottom and gets new images that are not even related to the subject mostly, just vague image, with 3x more ads.........................................
I am waiting until Monday afternoon, which will be a key indicator. I will also note Googlebot is slow to visit my website, it's like hardly visits at all, but it is not being blocked or has connection issues since I audited that part as well, which I found odd since it visited my site more than most bots combined for past three years on each given day.
