Is there a way to find out statistics for individual keywords that shows ONLY "Google Search Network" statistics without "search partner" statistics?
i know you can see this by ad groups by selecting segments, but couldnt find a way to do it for keywords. This is very important since i heard that keyword' s quality score is determined only by Google Search CTR, not "search partner" sites ctr
Quality score has several main factors not just CTR so it's not that critical to improving QS by viewing these stats. Spend time making sure your ad text and landing page text is relevant. If you have a history of good CTR your QS will improve.
When in the Keywords tab, click Segment to get the drop-down and then Top vs Other. This is the only way online but I would suggest running appropriate reports and export to spreadsheet or better yet, a database.
