Weaver Xtreme has been carefully designed to follow the basic rules used by most Search Engines – it is already SEO friendly. The built-in SEO features are based on the development efforts of the WordPress design team, and are identical to those used by the standard WordPress themes. Some of these features include generation of proper site titles that are displayed in the browser’s title line, as well as the ability to define global meta description and keyword definitions. And Weaver Xtreme generates HTML5 tags, which are further used by search engines to index your site. (And with HTML5, it is okay to have multiple H1 tags!)
If you need special SEO handling, you should use one of the several SEO plugins. We recommend WordPress SEO by Yoast.
