Welcome to the Q&A Forum

Thank you very much CMC-SD, Jared and goodlegaladvice for all your help.

@CMC-SD: As promised, I stole your analogy (Now I realize it was an analogy and not a metaphor, I think) and I tried to explain CMS to my girlfriend who knows nothing about computers. Unfortunately it did not come out as elegantly as you put it and we ended up eating bison burgers instead.

@CMS-SD: Great metaphor! I'm going to steal it But I already knew that about CMS's xD.  In fact my confusion was about what follows from that... If the pages are created dynamically and not retrieved from the webserver itself, how do would a backlink even REFER it??

I actually found this SEO blog touching on the subject matter: http://www.seomoz.org/blog/url-rewrites-and-301-redirects-how-does-it-all-work

So, pretty much this is how it works: A page is linked through the URL that is randomly generated by a CMS, but the webserver rewrites the URL that points to the original URL. Pretty much the same thing. And google indexes that URL plus the html on the page. Is that about right? That is why I should not worry at all.
