In the top ad positions on the left, I'm seeing Google frequently appending the advertiser's domain onto the title instead of appending Line 1 of the text ad. This is concerning for a couple reasons:
(a) The second line of the ad in those positions is the display URL which also contains the advertisers domain name and therefore if the domain name is already in the title, makes the display URL look very redundant in most cases (and therefore unecessary).
(b) The visibility of line 1 of the ad becomes far more obscure, relegated to small text in line 3 of the ad instead of large text in the title.
Why is this happening and can the advertiser control it and prevent it from happening?
