One domain? Multiple domains? What do you use?

[NinjaSteve]

When building sites or submitting galleries do you use one domain or multiple domains? I've always been curious about this.

Is it best to do style 1 or style 2

Style1
analdomain.com/analsite/
bondagedomain.com/bondagesite/
teendomain.com/teensite/

Style2
or is it better to do
domain.com/niche/sitename/

It seems better to have multiple domains, but the problem there is organization. You could be more organized with just 1 or 2 domains.

or domain/sponsor/site

multiple, but I don't think that it really matters

[NinjaSteve]

well I've heard some people using multiple and matching the niche and I was just wondering why. SEO maybe?

I use like niche.com/sponsor/sitename/ for AVS and use the domain itself for pay style sites.
I'd go crazy registering a domain for every site.

I do domain/sponsor/site for avs
and domain/sponsor/site/free for the free site version

I build a ton of free sites on one domain, but I also have a lot of domains. I used to get expired domains a lot..
