Free Text can be "a $$ killer"
 

Someone half way joked about Google not liking the word "free" in another thread. May be quite true.

Google don't like "FREE" the main reason if the Adwords advertiser giving any service as free sure he will advertise that site with $0.01 per click.

You have to be carefull what words you use on site with adsense or someone will smart price your site.

Using the words "FREE" a lot will definitely get you poor ads and a low CPC!
