It's been showing for a few weeks now on some ads. They just added a string of text ads to the bottom. Time will tell if this is helpful or harmful.
I have seen that a few times as well. I seem to remember a past post regarding this ad format, where Google has combined Ad Units with a Link Unit type format. I haven't been able to find any documentation on it though.
Well, it is one month old. It show randomly on existing add units, and it has few versions. One is AJAX add version which when You click one of keywords at the bottom of ads, change main ads
It's a mix of the regular ad units and a link unit. I personally do not like it... as I don't use link units on my sites anymore.... (well most of them )
this is the first time saw this type of ads how can i put it in my site does google support it in adsnese setup ? or it appear randomly?
