what is vb seo 3 ?
The new sitemap alters the way data is structured in fundamental ways. sitemap 3.0 segments different content areas into separate files, so you end up with a unique set of files per content type: forums, blogs, cms, groups, albums, members, tags, etc. In addition, the new sitemap has an extended priority feature that utilizes the built in 'weight' tool of the vbulletin XML sitemap generator for individual forums, CMS sections and articles to act as a multiplier.

We believe these changes are responsible for delivering increased returns for a number of forums from customers and testers we've been tracking. Please track your own progress via your Google Webmaster tools account, Google Analytics or gravity insghts .
