Test marketing with Adwords

I've started testing my sites with Adwords.

I put $100 in my Adwords account and ran some adds for ttjasi.com. Result: about 300 visitors and $8 in AdSense revenue.

Now I can change the ad text and run another $50 or $100 and see what happens. It is a great tool for honing advertising text at quit a low cost. If you wrote an ad for a magazine it would cost you a lot more than $100, you'd reach a less targeted audience, and most of all you'd have to pay whether anyone read it or not. With AdWords you only pay per click. If your ad is so crappy that no-one clicks, it doesn't cost you anything.
