SEO Filter Overview
SEO Filter is a flexible and extendable SEO Frankston – Search Engine Optimization Software for
forums and content management systems licensed under dual license GPL and a commercial one.
How does it work ?
SEO Filter optimizes the content of forum software and makes its links SEO friendly. Therefore attracting more search engines to your forum.

SEO Filter Process

Converts dynamic links into search engine friendly ones.
Generates keyword rich links.
Removes session id from links.
Transfers numeric ids (stealth method) as chars (id-0 => id-1)
Permanent redirect for pages (301) to avoid duplicate content penalty.
Clears stop/common words from links
Fixes titles to contain only current page’s title
Option to add keywords an description meta tags
Can have title and description multiple times (see misc)
Created link for categories (index.php?c=1 -> somecat…html)
Optimizes paging links (e.g.. Page 1, 2 ,3)
Optimizes previous/next post
Optimizes “last post” to point to the real link (phpbb2 module)
Removes parameters from the link that can have default value like
(postdays=0 or postorder=asc)
Aliases of forum files (viewforum => forum, viewtopic => topic)

The best part is that there is no need to hack forum’s source code (if mod_rewrite is available).
for more information consult the documentation of SEO Filter which is included in the downloadable packages.

Currently, phpbb2 module is available.
