I've found two keyword search from Google keyword tool:K1 run   (Phrase match,320,000 local monthly searches)K2 run   (75,000 local monthly searches)K1,K2 are not dictionary word while run is.Will it be ok to register domain: K1runK2run?Or should I go with K1K2run ?
Domain name coining issue
domains;name
1) There's more to search engines in the world. Which do you think would make more sense to your actual users? I think k1k2run.2) Doubling the keyword in the domain name probably doesn't benefit you at all. People will probably talk about keyword density and other stuff like that. But I would think the search engines are well aware of keyword stuffing and it applies to domain names as well.
