should i use subdomains or buy many domains?

Hi all.
i'm going to develop several sites organized in severla categories ... my question: do you think that is better to buy several domain names from a nich and display one article in each, or buy only one domain and make different subdomains for each article (or use folders with the main domain).
Lets say i have the health topic, and i have ten articles... should i buy ten domain names or just use a domain name with nine different subdomains?

will google crawl my subdomains just as it would a regular domain? will it take longer?

Thanks,

 

This seems to be a very similar angle to the thread I posted 1 minute after you

 

if you are just looking to post one article on a specific topic, then i dont see the need to get a new domain for each article. you can just post them on the same site. i dont even see the need to use defferent subdomains either. since it is the same niche, you can just use a blog and keep posting all the articles under one blog. or if you use a site, then just use the site navigation/menu to link to the articles

 

i guess both will get crawled, main site and subdomain too

 

Agreed, just build 1 site, not even subdomains, using a blog, or another cms or even a html template if you don't want a blog.

 

Thanks for your ideas! i will go with one site and many folders... a site for each niche.
