Your "Google Double Serving" rule is one of the biggest takeaways I got in a long, long time. Never knew that. That's why Conversation Domination rocks since you place as much unique content on as many web 2.0 sites as I can.

I got 2 more tips to add.

The best money sites I have are those TLDs with the exact keyword phrase I'm targeting in the title. For example, if I want to rank for the keywords "dog training". My site will be dogtraining.com etc. No additional words like "site", "online" etc. Obviously that's easier said than done. But when I find such a TLD I smile, because now I can dominate the SERPS with a fraction of the effort I take to rank for other products.

The other is using plugins like "Indexing Tool" and "Web Traffic Genius". These wordpress plugins help push your site in the SERPS by auto RSS submissions and the like. Obviously you need to use it in conjunction with other backlinking techniques but its 10-15 backlinks a day, per post without any additional effort. Really good for the deep-linking favor Google likes.
