Btw, guys - take a look at this page - is that illegal? 1. show_script.js is executed locally, not on google's server. 2. "Ads by google" is not a link, but text. 3. they look like not ads. 4. four units on page. I wonder why this site lives so long time, it seems that if show_script.js is executed locally, google does not know about all code changements?

But also very nice blending... If it's all legal, then I'll grab the idea I had about 20 clicks/day on my adwords from this page until I banned it.
To become a premium publisher you need more then 20M hits a month... This is locally-targeted shop, I can not imagine it gets ~650 000 hits per month. It seems he use the legal techniques...
Not only premium, there are more options available with AS. This site looks like one of those 'special categry' publisher.
