The way we build pages... ...and the way search engines see them. Though the Google Web Authoring Statistics study is few days old, I had the time to read and comment it only now. The study provides very little valuable or even new information related to SEO but, it does have several valuable points for anyone interested in web site development in general.

There are few issues I think are worth addressing in SEO sense:

* The study shows how Google has the capacity to detect and analyze patterns in document structures in very large scale (a billion documents in this case) and use that information to produce something useful... Identifying these patterns is crucial when talking about advanced IR methods, and one can only imagine the use search engines can come up with wide scale page structure analysis.

* The Semantic web is still far, far away... As the saddest part of study commented, page owners (developers etc) widely use structures that have been dead for a decade... With the way we (or most of us) build pages it is very unlikely that the semantic web and, in that sense, advanced search features provided by the semantic web, will ever occur in full scale.

As a summary I can say the study is a very impressive, but also very depressing to read if you know a thing or two about web development and standards.
