Is my Company Blog Affecting my Main Company Website?

[schmeetz]

mywebsite.com has a niche related blog on mywebsite.com/blog.

Should i be separating it with a subdomain blog.mywebsite.com? Could the blog content be diluting my website's message?

My Reasoning

Google Webmaster Tools --> Significance is leaning towards general terms (blog topics related) as apposed to mywebsite.com targeted terms.

always best to have site.com/blog as you don't risk SEs seeing the two as different sites. Rand spoke to this, so you might want to do a search on SEOmoz.

LOL, I don't know why it came out that I deleted also the first answer...

I confirm what said in the other answer and give you the reasons:

1. the blog in the same subdomain, like it is now, extends the long tail the site is ranking for (aka: you site is more visible for a bigger number of serps

2. the blog gives a voice to your site, the more relevant the more the content of the blog is high quality

3. all the links that the blog by itself obtains, are links that affects all the site, therefore also the "standard" part of it, helping its rankings
