SEO on Dynamic pages

[steve8428]

I have a website which creates a page based on the user input. It a motorhome site index, the main index has a map of sites which are all given a unique ID. When a user clicks on one of the site icons a full page is created using the unique ID.

Example the used clicks on site id=150 for campsite called woolpack the following URL is created

/campSite.php?id=150

and the page is created

If they select id=33 for site Kings woods the URL will be

/campSite.php?id=33

This all works great as the campSite.php generated a site page from a mysql database using the id supplied

Mu problem is with SEO. As I do not have individual pages for all the sites then I assume they will never be indexed so my overall website is very low on the google ranking. Is there something I can do to help with the SEO on this. It would be to much to create individual pages of all the sites if I have over 1000 sites
