Domain extension is a ranking factor? Does it change de value of my SEO

[Ex2]

Im trying to find a good domain for my business, but a domain for my country ".com.br" with exact keyword is not available any more.

I want to know if i buy a domain name with other extension like www.mykeyword.info or .biz is take bad effect in my SEO.

Or it doesn't matter?

If so, wich extension domain is good for SEO?

Thanks!

I would look for another .com.br domain, since that will give search engines a natural propensity to rank your site better in your country.  You can target this in Webmaster Tools, but with Bing they don't offer that, you have to rely on them properly Geolocating your IP.

I would hypothesize that .info domains are clicked through less due to spam issues, and as a side effect have lower positioning in the grand scheme of things.  I say this because of the revelation that Google and Bing both utilize clickstream data to some degree.

Also, .info or .biz just doesn't look good for a brand.  Unless it's built around that TLD like bit.ly or delicio.us
