Recommended article on Google's Universal Search Patent
Posted in SEO by Dennis E. K. Nielsen
Bill Slawski at Seobythesea has written an interesting article where he looks at the continuation patent for universal search Google has been granted, which could give us hints about how technology and processes behind search engines are changing. It moreover gives insights on how Google through patents protects their search technology. I highly recommend reading it, as it takes a great look at how search works and has more importantly how it has changed in the last dozen years.
