emd or branable domain

Hi all, I'm just wondering what you guys think of this.....I currently working on a new local site. It's quite a tough niche but the rewards are high. All I care about is traffic and conversions into leads. The more, the better. Do you think a 4 word EMD would be better than a 3 word...

About to build out a rank n rent website. this is just an example but it's close enough to get an idea: officechairshop.com vs officechair.shop It will be an exact match domain with the .shop version but the .com would have the additional word of "shop" in it. Which is best and why?

Hello Mates I am bit confused to selec the domain name for my amazon affiliate site, Should I go for the EMD or a brandable domain name ? If My keyword is "Best Fishing Reel" then which of the following domain name will be good. >. EMD domain name "BestFishingreel.com/net/org"...
