Using Subdomains to Increase Keyword Density?

[sbrault74]

I have a website on which I publish lots of news (sometimes up to 10 posts per day). I have a feeling that somewhat it is diluting the density of some keywords I am targeting.

By using subdomains, would I avoid diluting keyword density too much? Of course, I am talking about a reasonable use of subdomains (maybe 1 or 2).

What's your opinion?

I would probably just focus on having one site. If the posts are what you are trying to get ranking, then the keywords in that particular post help rank that post. If you are trying to get a category page to rank for particular keywords, maybe you should try building external links to that category page.

All that publishing should help support the keywords you've chosen for your primary domain.  If you are publishing pithy news that's thematically relevant to your main keywords, you could (sparingly) link from those articles to your news categories, in order to give them greater relevance.  If your news articles are thin and not in any way relevant to your primary terms then by all means, host them on another domain.

You shouldn't be focusing blog posts on specific keywords at all. Blog posts are best for long tail terms, so it doesn't matter how many you write. If you start writing multiple on one topic that is a head term you are shooting for, then you should have a category page for all of those, and that is the page that should rank for the head term.
