I recently rebuilt my business's website after studying seo for many months and experimenting with other domains. I have had great success -starting into the third week now, hoping it sticks I am starting to get quite a few highly targeted visitors on my site now that are in need of services in my niche and for the most part are ready to spend money. I am also getting visitors that are targeted, but are in search of freebies / diy type things. I am wondering if I were to run an ad campaign either with adwords or try to sell some targeted clickbank products, could this potentially change my serps in any way or make my site look less desirable to the SE's? Right now my site is completely ad-free. I don't want to hurt any progress I have made, but I would like to make some money off the visitors that I will not be able to deal with directly. Any thoughts? Thanks!
