A WebmasterWorld post shows two respected members reporting that they have seen Google AdWords URLs within the Yahoo! Search index.
Is anyone else noticing that Yahoo is picking up Google Adwords links? I only know because i append all of my Google and other PPC links with a src=#*$!X and my tracking software also appends similar information.
WebmasterWorld moderator, bill, confirms this saying:
I just noticed this as well. I hadn't checked my Yahoo SERPs in a while and just noticed that they indexed several of my AdWords pages. What's up with that? I guess the first question would be, 'how do we get them to stop it?' Do I have to change all of my AdWords tracking codes?
