When you search G (google) under the keyword: ebooks You'll find an adwords ad (number #4 on the list) saying, well forget what it says thats just an advertisement, but what it shows is all the other ads have titles you can click, but this one doesn't! Strange, anyone know why that is? Heres a fake example of one of these type of ads: (blank title, no hyperlink text, no title to click) We'd like you to buy our crap Yes we mean you. (the web address is here) ? This is like FREE advertising. I don't understand why google continues to allow it to stay up and not shutdown the ad. I've e-mailed google about this before, their response was, well I can cut and paste the e-mail if anyone would like, they basically said this though: Sometimes, certain users experience this problem when their personal servers temporarily disable certain links. I have researched the problem and was able to locate the ad you referenced in your email.
I used to work in the AdWords department and deal with this problem. At the time, it was caused occasionally when the person viewing the ad had certain anti-virus protection or other security software installed on their computers. Maybe that's the case with you as well.
