I wanted to advertise one of my affiliate products through adwords. I read the TOS and I didn't see anything about affiliate links. My question is if I use adwords somewhere in my ad do I have to state that I am an affiliate/aff. I know you use to have to but I'm not sure if Google changed the TOS. TIA
Not to my knowledge. The display URL is a differant story. Put your affiliate link in the destinantion URL Box. Use your web site or your parent company in the display URL Box. But!! only one unique URL can be displayed per page. So you may want to get a web site. I would say something about redirects for your web site but that would be against the Google TOS. http://www.superaffiliatemindset.com/increase-your-landing-page-relevancy-with-domain-aliasing/
Sure, you can use adwords directly, but do not forget to build a list of subscribers as well. For this, you will need a landing page. It seems a lot of work, but overtime you will have better quality score, your bid price will decrease, and you will have an unvaluable asset: a subscribers list.
