Modules:

SEO Tools

The plugin has set of tools aiming to improve SEO for the bbPress forums. Some tools will help you solve issues that some specialized SEO plugins might have.

seo_topic

Topic / Reply SEO Settings

For topics and replies you can control meta title and excerpt. For private topics and replies, you can replace normal excerpt with the custom version pointing out that content is private. And, you can add meta description tag into page header.

Other SEO Settings

For forums, you can override title set for single forum.

Also, you have options to add meta robots tags (into page head) for private topics and replies to stop search engines from indexing them.

Google Rich Snippets for Breadcrumbs

Plugin will modify default bbPress breadcrumbs to wrap them into markup needed for Google Rich Snippet Breadcrumbs support. This will work only if you use unmodified bbPress breadcrumbs!
