Is there any way to improve the ability of the pages in a forum being listed in the search engines? The index page of my forum lists well with the search engines but none of the others.

Well, SE Friendly URLs are a good start (option in UBB.T), and a sitemap is also helpful (I have a paid mod that lists out all of your forum topics in a sitemap; click here for more information)

I must be blind because I am missing the option. I expected it to be there. I will check into your site about the sitemap as well.

You have two options in the control panel.
Control Panel » Primary Settings

Enable Spider-friendly URLs?
Warning: This function allows most search engine spiders to crawl the community and also allows for specially formatted URLs, which may result in higher bandwidth usage and server load.

Note: The PATH_INFO environmental variable must be available for this feature to function properly.

Enable HTML Extension:

At least I think they are both there for your version.

Enable Spider-frinedly has been there since 7.0; html extension was added in 7.3 i think?

There are some SEO options since 7.3 as well i believe.

Sounds like I need to get off my butt and get updated. I found where to update the spider url but the note below has me pausing bc I have no idea what it means. What do I do to get that variable available?

Thanks for the help ,

One place to look is in the control panel>phpinfo.
Scroll through the list looking for path_info.

It may not show even though it is available.

If you are on a linux server it is probably enabled.
There are may topics on path_info here just search for them.

But just login to your control panel change the setting.
Don't logout
Open another browser and visit your forum.
If PAth_info is not set you will get a file not found.
If you do just open your browser that is logged in and switch it back.

Then you can research why by searching here.

Here Is one topic to test for path_info

I changed the setting so spider friendly URls are enabled and the forum is working fine so that should mean it worked correct?

Yes,
I just visited your site.
If you notice the urls look different now when you goto different topics and forums.

yeh, my sugguestion was going to be "Enable it, then poke around your forums, if it isn't broken, it's on" lol
