Yahoo letting GoogleBot crawl PPC links

ref=nofollow hello where are you?

[Easy_Coder]

I'm noticing that GoogleBot is running wild and crawling my Yahoo Shopping PPC links. What the heck? Anyone else noticing this behavior and was it valid or click fraud?

So what’s up with ref=nofollow? How come Yahoo is not using it on the PPC links? I'm seeing a META Robots NOINDEX, NOARCHIVE, NOFOLLOW but that's not working. I'm seeing all kinds of GoogleBot traffic coming in on my PPC Links out of Yahoo Shopping.

I'm reporting it but I wanted to see what was going on in the community too.

Are they indexing it or just visiting? I think the nofollow really means not to index anything as a result of following the link. I too have noticed the nofollow tag being ignored. It would be a problem if it was indexed as many of us would have duplicate content indexed.

I don't know if they're indexing. But I know I'm paying for the click. Yahoo has not responded to my question yet either.

I thought that rel=nofollow meant [do not follow this link]? The SEW Blog indicates:

If Google sees nofollow as part of a link, it will:

NOT follow through to that page.
NOT count the link in calculating PageRank link popularity scores.
NOT count the anchor text in determining what terms the page being linked to is relevant for.
