I just saw little up/down arrows next to the adsense on my home page on my home theater site -- it was a 160x600 skyscraper and the arrows were at the top, inside the ad box area, aligned with the "Ads by Google" when I VERY carefully hovered over them the cursor indicated an action (I didn't DARE click on them of course) but nothing showed up in the status bar during hovering -- What the heck was that?? Anybody else seen it on their site? I've never seen it anywhere before and when I refreshed the page it was gone. Is this something new they're trying?
I think Google are testing a lot of stuff out, some weird changes have been appearing/disappearing on Google and YouTube. Wouldn't suprise me with their adverts as well .
It just started happening over the past few days. Honestly I don't know how many people would scroll down to see more ads, but hey, someone might be curious too.
I think that's why they are testing these features, to see if they are profitable or not. But they should ask people to opt-in for their ads to be tested. It could affect profit.
