What the Conversion cookie does

Google uses cookies for advertising, including serving and rendering ads, personalizing ads (depending on your ad settings at g.co/adsettings), limiting the number of times an ad is shown to a user, muting ads you have chosen to stop seeing, and measuring the effectiveness of ads.

Who sets it
