Outils de recherche et référencement

C'est assez interessant : les developeurs de Google ont analysé le code source d'un jeu de 1 milliard de documents web pour en sortir des stats sur les balises les plus utilisées. Au programme :
# Pages
# Elements
# Classes
# HTTP headers
# Page headers
# Metadata
# The body element
# Text elements
# Table elements
# Link relationships
# The a element
# The img element
# Scripting
# Editors

Ce qu'ils en disent :

As part of our work with the WHAT working group, who are writing proposals for a new version of HTML, we have done some research into what aspects of HTML authors are using today. We took a sample of slightly over a billion documents, and looked at what elements were used on the most pages, what class names were used on the most pages, and so forth. The results are quite interesting!
