Campaign CTR and QS

Does Campaign CTR affect QS in high CTR ad groups?

[ipohopper]

I have a few adgroups under one Campaign and some are very good CTR and a few have very low CTR (mostly content impressions).

Does anyone know if a low Campaign CTR affects Quality Score in some of the high CTR ad groups that are in the campaign?

"if a low Campaign CTR affects Quality Score" : CTR may not affect your Quality Score in direct way but it will affect your overall ranking or the CPC that you pay for each click.
The best way to run content campaigns is to separate it from the "Search" campaigns. You will have to manage 2 campaigns but it will give you more control over all the metrics.

Google doesn't penalize you for running search and content in the same campaign. They account for the fact that content CTR sucks compared to search. The little question mark next to content CTRs even says so.

As for it's effect on QS, there are two quality scores: one that determines your ad rank (where you show up in the sponsored results, and for your landing page quality. The landing page quality score determines how much you need to 'pay to play' for minimum bids, and a whole bunch of other stuff. I'm not aware of CTR affecting landing page QS, but who knows these days....
