"sub.php?id=" in subpage web address

[Maslins]

I've noticed that a lot of my subpages have "sub.php?id=" shortly following the standard domain name, and just before detail about the page (ie "about us"/"useful guides" etc).

Is this doing me any harm from an SEO perspective?

Also, I think it is doing me harm from a viewer analytics point of view. I don't have Google Analytics, but have a similar thing provided by my web designer. Where it gives info about which pages people entered and exited my domain, "/sub.php" seems to just count as 1 page (ie anything other than the homepage is not broken down separately). So it makes it harder for me to see whether there's a specific page that people don't like and hence leave my site.

Is there anything I can do myself to fix this?

Any comments on this?

Maybe a teeny tiny bit but not enough to lose sleep over. Google thinks all your pages are identical anyway so changing the URL isn't going to make the slightest bit of difference.

I would think about moving away from the CMS you are using. You could create something very similar to this with Wordpress that would be easy to optimise for the search engines. The problem you mention isn't major, but the fact you cannot get good analytics data is. "If you can't measure it, don't do it" Michael Dell I think. You really do need to vary your title tags and descriptions:
