There's no ads.

Over time I've change page URLs, partly as a migration from Blogger to Docusaurus, partly due to just changing page URLs without thinking about it.

I've changed image URLs by switching from PNG to WebP and back again.

Thanks for the link will check it out.

that was the latin "ad" aka "about"

mobile friendly tests fails see https://search.google.com/test/mobile-friendly/result?id=SAu...

and google can not render the page correctly

also test with GSC page inspect -> render page -> see screenshot

if this correlates with the software update (and the page URLs) did not change, then this is the strongest contender.

check the crawling metrics in GSC google search console

js, css average load time should be max 200ms- or it is some other asset delivery issue

html not more than 400ms average response time

note: i am the author "understanding seo" https://gumroad.com/l/understanding-seo/hacker-news (think seo for hackers) feel free to mail me, contact in profile

everything points either to an page URL change or 4 SEO tests issue - from my point of view

written on a mobile in the metro, so can not check in detail right now

> that was the latin "ad" aka "about"

Latin "ad" is more like "to" or "toward", but I've never seen it used to mean "about". FWIW.

You might be aiming for "ab", with which autocorrect will likely refuse to cooperate.

ok, new learnings, "ad" in the meaning of "about" is not used like this in english.

in german the latin "ad" is used as "about that point" and even part of the Duden (basically the official guide to the german language)

https://www.duden.de/rechtschreibung/ad

did not know that its more a german thing.

additionally misconfigured /tags/

i.e.: https://johnnyreilly.com/tags/authorisation shows the full content of the first one, this is also the ones which get indexed, see https://www.google.com/search?q=site%3Ahttps%3A%2F%2Fjohnnyr...

a.k.a. massive self made internal duplicate content
