SEO: The new Google Patent and the new quality guidelines provides a great analysis of the new Google Patent issues on April 26, 2007.When reading it remember that the patent is a theory. Google may use all the techniques describe it exclusively. They may not use any of them and/or they may use techniques for indexing and ranking pages.
The best technique for fighting spammers is disinformation to send them on wild goose chases. What better than to patent stuff you don't use?
You can ignore all these patent formulas is you create a useful and interinteresting experience for your users, remembering that the search engines basically read text; ie: your flash and graphic files won't provide them much food.
You should also take the automated web page generation programs, templates and the like and shove them where the sun don't shine!
