Google's Webmaster Guidelines page is where pretty much all SEOs should go to get their start. And even after starting, it's a great place to reference. Now Google has updated their Guidelines page to be more current. There are a variety of changes and this article goes through them line by line. Among the changes:
- Some added language about alt attributes for images
- Google now recommends a sitemap not just for itself, but for human eyes as well
- They specify what "a reasonable number of links per page" is
- Googlebot may have more capability than we expected when it comes to reading text in images
And a host of other changes. The image references are probably the most interesting. Many SEOs reacting to the changes are surprised that Google's quality guidelines are the one area that was not touched at all.
