do have a *-* in domain name matter?
 

do have *-* in domain name have any influence on listing and seo?
like example: daily-motion (i know that site already exist)

No, SERPs generally ignore punctuation.

pretty much just a affect on type in traffic in my experience

this is probably bad with Type-in traffic
surfer are not usually use th *-*

sharphead cool avatar!

some say it might be even better for seo, as the keywords are separated and more obvious, but at the least it doesn't hurt seo at all

it hurts type in and word of mouth advertising or advertising that is not on the internet ie. tv or radio etc, but for sites that are linked and seo-ed it should be no difference
