Does "Using a dash in keyword name" affect SEO?

[kysizzle6]

I sell machinery branded Co-matic.  Most people search Comatic so I was wondering if I should change my keywords from Co-matic to Comatic.  Would the change have a significant impact on SEO?

Thanks!

No having a dash is not going to have a significant impact on your site as far as rankings... However typing the URL into a browser manually will be easier, and a shorter URL in general is better.

If you can avoid the hyphen then do it. If you must use the hyphen, it should not impact your SEO results.

Matt Cutts has stated before that a dash - in a URL is interpreted similar to a space while an underscore _ is interpreted as a connector. http://youtu.be/AQcSFsQyct8

In your case, if Co-matic and Comatic are synonymous then I would choose whatever the actual Brand name is. Odds are Google will understand 1) that the brand is Co-matic and 2) that "Comatic" is "Co-matic" when looking for machinery.

Also, "Comatic" has the dictionary definition "of, pertaining to, or blurred as a result of a coma" which I don't think would be advantageous to have associated with your site.
