search engines dont like it because when done correctly it can significantly boost rankings and brings up some ethical editorial questions. if you go down this road do your research first so you understand the risks, rewards and the right and wrong way to do this.
I wonder if it would be safe to assume the OP was asking about in-line text ads by the likes of IntelliTXT, Kontera, Clicksor and such. you know, those pesky pop-up ones when you hover your mouse over.
I've been using several of those networks in the past and I'm growing very tired of them and I'm just on the fence about pulling all of them off. They used to work a year ago or so but since then the effectiveness went down. But even more than that, in the light of Google's latest stand on page load time used as a ranking factor, I've looked at the JS-generated code. Their code (don't want to name any networks - it's pretty similar between them) is a poster child for bloated code. Abandoned images in CSS, dozens of DNS requests going to any number of very strange looking domains, nothing cacheable - you name a site speed issue, it's there!
I wonder if anyone here has already pulled a plug on the in-line ads and has any feedback on the results.
