One of the most popular forum packages on the internet is phpBB which is written in PHP. The abbreviation "phpBB" stands for "PHP Bulletin Board. This is a free software avaible under the GNU General Public License, so it is widely used".

Although this software has evolved over the years, phpBB is unfriendly to search engines, which limit the ability of the web page owners to take advantage of the huge amount of free content that their users are generating.

So What's wrong with PHPBB?

• Dynamically generated, long URLs that are SEO unfriendly
• There are no keywords in URLs
• Different URLs show different content
• Search engine spiders index the "View latest post", which generally should not be indexed.
• ID Sessions are read and indexed by spiders.
