3 ways Google knows you’re clicking on your own adsense ads…

June 17, 2007

Have you ever wondered how Google knows you’re clicking on your own adsense ads? There are even people who email Google that they accidentically clicked on their own ads, afraid of being banned.

But Google says that it’s no problem, you don’t need to report it, they’ll find out themselves! So how do they do that? Here’s my guess:

  1. If you are still logged in to Adsense, they know who you are via the Asense cookies.
  2. They track the IP of the computer from which you are doing your Adsense administration. If any clicks come in via that IP, they’ll most likely mark it as suspicious. Even for dynamic IPs, it gives them at least a pretty good guestimate.
  3. They track your behaviour on your own site, and detect it matches “site owner” behaviour. Probably in  combination with Google Toolbar if you got it installed.

BTW, you can easily prevent accidental clicks during testing by adding this to your adsense-code:

google_adtest=’on’;

Any clicks will be ignored, as long as it is set.

Lessons learned during building your own website

January 25, 2007

Below are a couple of things I learned when creating my own website. The points mentioned are mainly about things you really need to think about in advance as much as possible, *before* you start.
It will save you quite some thinking and issues later down the line… Not that they are unsolvable at a later stage, just nasty to do afterwards, for example when the site is already live.

– Have a square icon/logo. This way people can put it on their sites/blogs etc. They are more willing to do this if the image is relatively small, compared to your full sized logo. Make sure it looks still pretty good in favicon.ico size and in 16×16 and 24×24 (firefox extension image size).

– Think in advance whether you want users to be able to resize your whole page (fluid), or have it fixed size.

– Get a framework. For PHP think about PEAR and CakePHP. For Java, get Spring.
