virtual subdomains with database locator

understanding how spiders start a new site

[CoMotion]

I'd appreciate it if someone could offer some clarity to how SEs locate a new subdomain. The picture of the situation is here:
www.manufacturingsite.****
company info
product info
other stuff
DEALER LOCATOR

db driven, no hard links, link to
dealername(1-60unique).manufacturingsite.xxx

All of the dealers have dlr specific content, common look and feel and ties to their own back office systems. Every dealer would like to think their site can be spidered and found. I don't see how, and in fact they are not being spidered.

Thanks for participating in the discussion!

Welcome to WebmasterWorld, CoMotion!

SE spiders find sites on subdomains just like they find any other site by following links. How you generate your site's content does not matter to the SE.

Thanks Andreas. The question isn't truly about the content. The problem, as I see it, is that these 'virtual' subdomains are not hard linked from anything. The way that one would find one is to click a map or type a zip code. Since there are NO links to these domains, the bot isn't able to 'choose' a map or type, how would the bot/spider know a subdomain existed?

I hope this clarifies this a bit.
