I have a domain, let's call it example.com, which has a subdomain, games.example.com. I maintain a games forum using phpbbseo which is located at games.example.com/forum. The problem is that the forum is not being crawled. I used Google's webmaster tools and tested that the page is seen by google.
There is a link from games.example.com to games.example.com/forum.
What can I do? How can I make google crawl my forum?
