They felt your ads we're not sticking out enough, so they fixed it . Nah, sounds like they may be test driving a new format (like the pictures, and unbranded) but who knows why they would do this one -- seems rather pointless?
Probably link title is in some weird language (chinese, japanese) and you don't have a good font to render those characters. Funny, anyway.
I had an English language ad yesterday render in a foreign language. I didn't have the appropriate language pack installed, so that one ad showed up as a bunch of garbled characters while the other ads looked fine. First time I'd ever seen this, so maybe it's a related issue.
3 unit ads on my web and for every unit, 1-2 of the ads are not showing the title. I thought it was my eyes so i went to sleep. haha
Just did another post about it! It's all over the place and it is hurting the CTR badly!! People don't click since there is no title... just some text! What's next? Accuse you for using gMail for spamming? Tell you that your site is not yours anymore since they have it in their cache, so then they have the right to it?
