Welcome to the Q&A Forum

Hi David, First of all as far as I know paid campaign doesn't helps in organic ranking. Google repeatedly said that paid campaign doesn't affect organic rankings. As far as I know Google says that showing one version to users and other version to boat is called cloaking and we must not use this but didn't say anything on paid & non paid visitors. If I assume that paid campaign helps in organic ranking then it is the only one thing that can affect ranking by paid campaign that is CTR. I do run AdWords campaign for my website over 8 years and CTR is minimum 10% but I never noticed that paid campaign helps in ranking. ** I wouldn't suggest you to do that*** Please also check this once @ https://support.google.com/adwordspolicy/answer/6020954?hl=en&rd=1#701 Hope this helps you. Thanks
