I was recently with a client reviewing their AdWords account. I noticed that they were bolding certain words in the title copy for all their PPC campaigns. I have never seen this done before and after doing some research, I’m not sure it’s worth the valuable real estate in the title field. You only 25 characters to make a catchy title and to take up a 1/3 of that to bold a keyword(s) feels like a waste of space to me. Also, people generally start to turn out effects like this if everyone starts to do it.
Does anyone bold their title in PPC campaigns?
