WordPress MU

Hi. REALLY new to all this and Mu.

If I install multiple blogs on my site using mu, what will each blog's address be?

Is it:
http://www.mysite/newblog
or
http://www.newblog.mysite.com

Or do I have a choice?
Thanks!

They will be http://mysite/blogname or http://blogname.mysite/ depending on how you install it (and assuming you've got DNS wildcards turned on)

Thanks, Steve.
That's too bad, because I am pretty sure that search engines treat sub-domains as different sites. Therefore, all the content on all your different blogs will not have a cumulative effect and all be seen as coming from the same well-developed site. Am I missing anything with that?

I have to admit that I went for subdirectories because all my blogs share a "theme" (that's subject theme and not visual theme) and it allows me to do clever things with googlemaps (which is problematical using subdomains)

Well, given MU is a blog farm, then yeah - all sub-sites would be seen as seperate.

IMHO, they should be. Which is good, I think.

Think about the ratio of "well used blogs" to "one or two and done blogs" on an average site.

The latter typically outweigh the former by quite a bit.

That being the case, would you want those sites bringing down the perception of your main site? They can have an effect on it.

IMHO, being counted as separate site is better for that as the "penalty" of a "lesser" site linking to you seems to be less than if it were considered as part of your site.

So yeah, technically it looks like more content available for your site, but sometimes "less" is more if you know what I mean.

In simple terms, more relevant content (while less in number of pages) is better than more content which is less relevant. I can't see how 1000 hello world and welcome to my site posts would help your pr or ranking. It can sure hurt it though.
