I think they're fantastic and make the TEXT ads looks so much more appealing and professional.
Does that mean this will increase CTR? Who knows.
@ JS Harris My bounce rate is already 90%, so I can't go much higher! I only have a few pages, that's why, but my site remains highly ranked in the SEs. I'm worried I might get "reviewed" at some point and knocked down. But how can they knock someone down if they only have a few pages on their site for visitors to go?
