I ran this keyword for a month on adwords. My Max CPC was $1.56, 11.11% CTR, Avr. CPC was $0.29 per click. Question, if I lower the Max CPC, will that improve my Quality Scope? or should i just leave the Max CPC along, it dont change anything?
Personally, if the conversions are where they need to be I would leave it. That's just me though, opinions may vary Related: "Ad placement is based on your maximum cost-per-click (how much you're willing to pay per click) times Quality Score (Ad Rank = maximum CPC x Quality Score). For the top positions above Google search results, however, we use your keyword's actual CPC.

The adwords algo goes like this >> MAXCPC x CTR x Quality Score = Ad Score. If conversion is ok, yes leave it. If you are trying to improve your profit margin than create a new campaign and test there.
