What the _gac_gb_ 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.
The name ends in a part that changes from visitor to visitor or site to site, so this entry covers every cookie whose name starts with _gac_gb_.
