What "SEO spam" you talking about? I'm searching for "air purifier" right now and my results are:

1) "The Best Air Purifier - The New York Times" (makes sense)

2-4) Links to "air purifier" category on Amazon, Home Depot, and Best Buy (makes sense)

Then a "discussions and forums" section with a couple of links to Reddit (makes sense)

Then a Google buying guide full of common Q&A about air purifiers (interesting), a list of shopping links to popular air purifier models (makes sense), and YouTube review videos (makes sense), all interspersed with some more top stores, brands, and review sites (Costco, Blueair, Levoit, Consumer Reports, Better Homes & Gardens -- all totally fine).

All of this seems perfectly reasonable and, indeed, exactly what I'm looking for. I have zero complaints. I can't find any SEO spam whatsoever. Literally all of this in the first couple of pages seems entirely legit.
