Some of this stuff is common sense..and the rest is like a real good speed trap!
eBook sites that show frequent
ads - 3? 5? per page huh?'Get rich quick'
sites - Soooo, if I am a drop shipper and my clients get rich am I in violation? Or is only if you use the words get rich? Maybe they just have some super secret list on not allowed products and schemes? :?
Travel aggregators - Crap, these are actually useful sites! Not better way to get a good price on a flight.
Comparison shopping sites - These too!
OK, so maybe the Get Rich thing is a stretch...But ebooks, and Travel sites, and shopping comparisons are things I USE. Are they not viable content? Why should they be any different than any other site? I personally think they have just as much right to monetize their sites, and Google is only sending business elsewhere.
