"the more words in your domain, the less SEO impact each word is going to have. At some point, it may start to look a bit spammy." I think I missed a good article on this can you please provide a source?
I would not use this for over the phone lol... Only to tap into search engine traffic, lets say I found a term that is highly competitive. However, the rankers are not optimizing for that specific query. Its only highly competitive because these sites are authoritative for other relavent keywords.
Example.
I want to rank for the keywords "how can i be sure this is true"
When I type this in a search engine, lets say I get youtube/ebay/etsy/etc... for the SERP (highly authoritative according to SEOmoz but they are not targeting the long tail question)
Would I be better off buying a domain canthisbe.com? I dont see how this makes sense....
