Hi everyone,
When I search for a random term like "hoshino892" on Google, I notice that pages from large, reputable sites (like Goodreads, PosterMyWall, etc.) are showing up in the SERPs with spammy query parameters — for example:
https://www.postermywall.com/.../search?s=hoshino892
It seems like someone is abusing open search endpoints or URL structures on high-authority sites to get spam content indexed through Google.
I want to build a tool or system that can replicate this kind of behavior, but I can’t find any clear documentation or guides on how this is actually done or what it’s called.
Can anyone help me with the following?
Any help or pointer would be really appreciated

Can anyone help me with the following?
- What is this method officially called?
(Query Injection? Index Hijacking? Something else?) - What keywords or phrases should I search to find more info about it?
- Are there any scripts, case studies, or examples of this kind of automation?
Any help or pointer would be really appreciated
