In position 5 on google.com is a Facebook page with 20 likes of a music band that is actually called the same name as the search keyphrase (adjective-widget). MIGHT make sense if it was a popular Facebook page, but 20 likes?
I must disagree, as the likes nowaday are sometimes "spammy" as many companies pay ads per clic in facebook saying for exampel, if you like this clic like, I seen competitors with more than 14.000 likes using those ads, while my site has only 180 but they are natural. Isnt this a new kind of spam? Or should I do the same? Its good as 14.000 will see what you post, but for google to use those likes as a quality meter, I dont think google should.
