I have a website for my offline business which has about 47 pages. I just checked today and somehow there is CPA links scattered throughout my pages! The words are highlighted to an offer. I worked so hard to get it to number one hopefully google doesnt penalize it . Can someone tell me how to someone did this and how I can prevent it from happening in the future. Also is there any special things I should be doing besides removing the links so that it does not affect my rankings?
