I have the privacy settings cranked up. Google is no doubt still looking but isn't supposed to use the info, hence I get random adverts. The random ones cost less to the advertiser, hence its all Russian brides and payment protection rackets.
What I never got when buying Google adverts was why you'd target buyers. If I just bought a Suzuki, chances are Honda are wasting their time. Amazon is worse, they know you just bought. Now if you googled motorbike dealer, then the paid ads should trigger.
My current banner is for Age UK. A charity, so either paying the lowest level or getting it free as part of Google's clean up after the tax thing. That or they think the club could contribute a few extra old blokes.
