Exact Match Domains

I hope what I'm trying to ask comes out right....

If I find exact match keyword domains that are available, is it better to have one domain per keyword for SEO purposes? For example.. lets say "bluewidget.com" is available so I build a site for it.. but then I find another keyword that the exact domain "smallbluewidget.com" is available. For SEO purposes would it be better to optimize a page of the first site for the new keyword, or to purchase both domains and have two seperate sites in the same niche?

Thanks!

Exact match for me tends to rank very well; however,if it were me I would probably make small blue widgets a sub page. That being said if you want to buy two domains you will probably rank faster for both terms, but it will cost you a couple extra bucks.

It also depends on the project, if you're making a 20+ page content site or a 6 page sniper site. If it's a broad niche - go with TLD and make subpages, if its a sniper site do each individually.

Me kinda rambling, hope that helps.
