Welcome to the Q&A Forum

George provided a great link. You certainly need to be aware of the amount of links and anchor text you are putting out in the world. I believe Cyrus Shepard mentioned a very good alternative to carpet bombing footer links inside a template you made "... instead of a footer link, how about a single, well placed editorial link somewhere on a real page? (this might be hard to manage with some of your clients, but it's worth a shot).." I like this option because I am personally of the impression that if you are paid to develop a website then you should also be up front about any other benefit you receive by doing so, and a link (advertisement) is certainly a benefit to you. This could and should IMO be negotiated in a professional manner with the client. Now if you are just selling templates ala template monster or a similar site, then I would remove my name from it period. Since you can't control what happens to the template after it is downloaded. Hope that helps.
