HouseFresh (an affiliate website owned by a SEO agency) are complaining they've virtually disappeared from Google Search results due to factors including "keyword swarming" (multiple pages / articles on the same topic published on multiple sites owned by the same competitor publisher) - this is as old as the hills but Google could improve SERPs by reading the business sections of the newspapers
I think it's a no-brainer to say that greed has changed Google from focusing on providing the person searching accurate and relevant results. Which is unfortunate since they are the best in the business as no other search engine is close to what Google has accomplished.
It makes me wonder if AI tools will level the playing field more?
