As you can figure out Google got this technology from its acquisition of DoubleClick. DoubleClick isn’t a privacy advocates’ darling but Google tapping into DoubleClick for better monetization (in these ‘recession times’) was inevitable. DoubleClick by no means is the only ad network to use this kind of technology though.
Many of the advertising platforms using this targetting are a member of the Network Advertising Initiative. You can go to the Network Advertising Initiative Opt-out page to see if you currently have any such ‘tracking cookies’, and opt-out of them if you want. Note this this opt-out preference itself is stored using a cookie, so when you clear cookies in your browser this preference will be lost and you’ll have to opt-out once again if you want to.
Specifically for Google’s case you can go to the Google Ads Preferences page. Here you can block the DoubleClick ‘tracking’ DART cookie using a cookie-based opt-out; or if want to opt-out permanently then install a small plugin to do so so – this is for Mozilla Firefox / Internet Explorer users only. Losers Users using Safari and Chrome can read the instructions for their case.
Oh, and just case you want to see ads based on your interests, you can choose areas of interest from the same Google Ads Preferences page (obviously, don’t choose the ‘Opt-out’ option if you’re doing this).
