Google Content Network Image/Text Ads

[cyberkiller]

Is it worth creating a different ad group within a campaign with the same keywords for your image ads and one for your text ads or will google treat them the same if their all in the same ad group?

Because some times image ads get a better CTR than text ads and vice versa and im wondering if that can hurt your QS.

Content Network CTR doesn't affect your Search quality score.

Separate ad groups. As you said, they will mostly likely have different CTR so you'll want to set different bids for each of them. More work but worth it.
