Hey, do you guys know if hidden divs are detected through adwords? and do they improve or worsen your quality score? thanks
Yeah, How could they not detect it (all they see are source code)? Making them hidden - if you mean through CSS, the bots don't have a monitor so CSS attributes mean nothing to a bot. If it's done through server-side programming or Javascript, that might be questionable, but it's probably that it will be detected - or at least, it will know that something Is hidden and therefore will lower your score regardless of the hidden content.
Yeah, if Google can detect that you're using them (not necessarily what's inside) - which it definitely can, then my advice would be steer well clear
is it worth trying? probably not. you might get a small gain, but on the flipside you might get a big hit.
I've tried it for a campaign in which the Landing page contained a single Image and I had put a some of my keywords in between the comments tag. This seemed to have worked for me.
