Title: phpBB SEO Optimal titles
Description: phpBB page titles Optimization.
Author notes:This mod will optimize phpBB pages titles.
By Default, page titles contain many useless information, such as "View Forum" or "View topic".
This mod will better target words to use in titles, using topics, forums and categries titles.
In addition, this mod will add the page's number in page title, which allow for a lot better pagination indexing. As two pages with the same title are hard to keep in SEPRS.
All this without any SQL queries.
A must, whatever you SEO strategy.
