I have a site that's running a phpbb forum, and google seems to index specific number of pages from the site no matter what I do. The problem is that many of the pages google was indexing were worthless such as the login for private messages. Following the advice of this post...
[
webmasterworld.com...]
...I created my own robots.txt file:
User-agent: *
Disallow: /groupcp.php
Disallow: /login.php
Disallow: /modcp.php
Disallow: /privmsg.php
Disallow: /search.php
It worked like a champ and now Google is getting at the good stuff and leaving the spider poop alone.
Thanks for the tip!
