for the purpose of this question, let's pretend my target keyword is "cosmetic dentist San Diego" I have a page on my site www.sandiego-dental.com/cosmetic-dentist I wanted to rank this page for "cosmetic dentist san diego" This inner page was #7 for "cosmetic dentist San Diego". I am not sure where it was for pure "cosmetic dentist" without san diego. so during a period of like a week, I commented on like 4 high PR, low OBL blogs every day. For a total of about 30 links. Anchor text was generic like "here" "this website"....unfortunately, page moved from #7 to #16 Then I stopped, because I thought maybe blog comments are toxic now? today i noticed "costmetic dentist" without san diego is sitting at #1 but san diego is still #16 What do you think is going on? Isn't the pure keyword without san diego harder to rank? why is it higher? or maybe it's not harder to rank? as far as I am concerned, the pure keyword is worthless, I havent seen any increase in traffic. how can I rank that page for "cosmetic dentist san diego" instead of "cosmetic dentist"?
