Just wondering what others think about having the www in the display URL. I've been running an ad with the www in it for ages now but I'm just wondering if I should remove it or leave it be. It's a longish url of four words and I was thinking it might make it easier to read without the www. Do you think having it vs not having would effect quality score (if hypothetically ctr didn't change)? Is either perceived as better or more trustworthy? I've just done a few searches for a range of completely different things and most ads seem to have the www.
