[a bit of background:]
Our site is a totally legit doctor booking website, in an European, non-english speaking country.
10 years old domain, decent trust, so that's not YMYL stuff - but surely we're in a medical related niche. Site architecture basics are great, speed is top notch, been ranking well for many years and we keep our garden clean.
The August algo update didn't crash our site altogether, but we do have this strange behaviour on some pages, guess what, the ones that bring most revenue....
[the specific issue:]
A sample SERP for eg "Dermatologist in City1", until a few days ago, would have brought a listing result from our site, so the user would be served an useful page with a large list of Dermatologists, their user rating, their prices, etc. Quite a lot of information to make a good choice.
After the update, a few days ago, those listing pages are literally substituted in the SERPs by random "single product" pages from our site, like Dermatologist X Y - which is better than nothing, but are much less useful to the average user, and harming conversions.
These "Single product" pages look like randomly picked by the disappeared category - sometimes they make sense, and they are rich in content, some other times they thin pages - very strange.
I've been searching the Internet for articles describing this phenomena, maybe in the wrong way, but I haven't been able to find anything relevant.
I see some competitors having the SAME EXACT problem, so I think this is a pattern of some type - and it's something that's coming from the August update, for sure.
Is anybody else experiencing this kind of issue?
