I am somewhat new to SEO and appreciate any help. Would it be a good practice or a not so advised practice to buy OurKeywords.ourcompany.com and point them to our main site?

That is pretty much my question.

As Andy said, you don't need to buy subdomains you need only set them up. but simply pointing a domain or subdomain to your site will not help.
Setting a separate website on the domain, can help, but only if that subdomain has links pointing to it, but then you would be better of getting the links to your primary domain. so I would not bother.

Hi Travis,

There is never a problem with buying a domain and then just pointing it to your primary site. Problems only arise if you were to buy a domain and then populate it with spam / duplicated content that then linked to your main site.

However, I am a little unsure by the example you gave above, as this looks like just a subdomain of your site, in which case, you won't need to purchase anything and it just requires setting up. Again though, fill it with content (unique) and SEO it as a new site.
