I ordered some tea over a month ago and I'm still seeing ads for that company on my site. Why would Google think an ad for a site I already order from would be something I would click?
I used a popular online tax filing service this year. For the next month pretty much every adsense ad I saw was for this service, which I had already purchased.
No wonder people aren't clicking as much.
