I was wondering if I can get some advice on how to outrank sites such as the yellow pages, yelp, etc. for local seo purposes. So far my strategy has been latching on to parasite sites ( I won't named them for obvious reasons) I have been getting nearly instant front page rankings with no backlinks or anything using this method for local seo! However, I am having a tough time finding parasites that can outrank those sites (yellow pages, yelp, and other general sites such as this), websites like these are kind of a pain in the neck to figure out how to outrank. Should I be building backlinks to my parasites? Does building backlinks to parasites even work anymore? Thank you .
