Best way storing data for proper SEO

Another question regarding the "pseudo" project I'm writing documentation for.

On the website one will find a lot of charity organizations. Each instance will provide detailed information regarding this organization.

My first thought was a single page that load the company information from the database.

But then, I want the site, together with all organizations to be properly indexed by search engines, and my concern is that if the company information is in the database, this is not going to happen (Probably I am wrong, but I'm not sure).

Any ideas?

Nearly all non-trivial websites are powered by a database.
A search engine doesn't know or care where the content comes from, so whether your application grabs it out of a database or whether it's a static page is irrelevant. What matters is that they are all linked together appropriately; the URL schema is sensible (e.g. /products/tables/55 rather than products.php?prodid=18755&cat=18); and, of course, the markup is clean and appropriate.

yeah, moron me should know of all people, as vbforums post keep showing up when doing a google search for our company, as the company name and link was in my signature. much to my embarrassment sometimes

If possible, could you elaborate on what you said? I mean tell more about what one should not do (like using query string variables as you mentioned)

Also, I'm pretty new to php (hey, i can code and i know php syntax...just need to learn a bit more), so can you tell me how do one, for instance, make www.mysite.com/clients/jumbo open the page mysite/clients/jumbo_jet.php.

mod rewrite will do what you want. http://www.modrewrite.com/
