I live in Argentina, and sometimes I search for Argentinian things, but also more often I search in English for things related to work, travel, hobbies, etc. It's reasonable and OK that when I search for certain things Google provides region-specific results (e.g. "servicio meteorológico nacional" [National meteorological service] brings up the Argentinian agency and other local results instead of any from other Spanish speaking countries). This has been like that for many years now, and is OK.
The new thing is that more and more often I've been getting results that include argentine or Spanish-language results that have NO relevance to the search, and are a super big stretch.
I haven't saved examples, but I tested for 3 minutes and just came up with one... trust me that I've seen much worse than this.
Let's say I search for "french tv cat puppet" (I watched an old show called Telechat when I was a kid). I get the following results:
1 & 2 - Kitty Cats - Wikipedia (a French Canadian TV show... OK...)
3 - Pacha et les chats @ imdb (the same show)
4 - YouTube (???? "Missing: french cat puppet", warns Google)
5 - "Carmel: Who Killed Maria Marta?" @ Netflix (this is a true crime show based on a very famous murder in my country)
None of those results were ads. I have no idea why Google would show results 4 and 5 except to think that their index for my country is very very broken/corrupt.
Another "not as bad but still very bad" example: If I search for "mccartney bear song" (see Rupert and the Frog Song, and the "We all stand together" song) the first two results are spot on, but the third one is a Spanish language result from a local paper titled "These is the full list of songs that The Beatles played in the Get Back documentary by Peter Jackson", the snippet has McCartney and the word "song" from "Song Of Love" in bold.
Final one. I search for "retro toys with water inside"... the search terms are super poor, but the image results show me that Google got me (e.g. the Tomy Waterful toys).
Image results - OK
Video results - OK
1 - Handheld water game @ Amazon (OK...)
2 - Pinterest results (groan...)
3 - A hacked home decor Argentine site that redirects me to a page that sells a doll, no water.
4 & 5 - Relevant retro toy pages
6 - A hacked Argentinian government page (under the .gov.ar TLD, which is for government site) with the "classic fashion CHATHAM ELECTRONICS JAN-CAHG-1Z2" title. Apparently has been fixed so now it has a 404 error.
I rest my case. It's a disaster.
