To add meta tag using plugin…

add_action('bb_head', 'meta_bb_header');



function meta_bb_header() {

echo 'Your meta tag here';

}

Maybe you can use ping service like Ping-o-Matic that were design for blog, to notify other service that you have update your forum. Never try it yet with bbpress so kinda don’t know how it gonna be

Another alternative maybe submit sitemap at Google Webmaster.
