my competitor has been advertising via adwords or adsense or whatever it's called. I am talking about the yellow background advertising at the top of the serps. They come up for every single motherfucking keyword that I am targeting, plus more. they have been doing this for years but this didn't use to bother me too much because I would still get some clients. but ever since they started showing 5 stars next to their ad, my traffic has dropped to basically zero. everybody googles, sees the stars, clicks, and buys from them. so I dont know what to do, besides advertising with google, what else can I do? for now i have tried to add authorship to make my site a bit more attractive in the serps but the picture hasn't shown up yet. what else can I do?
