I strongly advise everyone to study the full content yourself. But I will point out some of my findings.

Optimization Tips
1. ads that performs best: 336x280 large rectangle , 300x250 inline rectangle, and the 160x600 wide skyscraper.
2. ads should position around the main content.
3. Ads that blend in and inline with the contents will catch most users' focus.

Webmaster Guidelines

1. "Use a text browser such as Lynx to examine your site, because most search engine spiders see your site much as Lynx would. If fancy features such as JavaScript, cookies, session IDs, frames, DHTML, or Flash keep you from seeing all of your site in a text browser, then search engine spiders may have trouble crawling your site."
2. Make use of the robots.txt file on your web server. Add an empty file if there isn't.
3. Don't use "&id=" as a parameter in the URLs, they will be excluded from the index.

Submission Advice

5. Submit your site to relevant directories such as the Open Directory Project and Yahoo!, as well as to other industry-specific expert sites.
