What would happen if you ran Google ads for a parasite page?

Say, if you ran an ad for 'best tv Facebook', with the intention of getting clicks from people searching or Facebook pages about best tvs, could you get in trouble? By Facebook? By an affiliate that you link to within that page?

You can target brand word(s) in keywords in Google Ads, but not in the ad copy. If your landing page (website) has good quantity and valuable content, then 1 or 2 affiliate links are usually not a problem in running it in Google Ads.
