I'm looking to build an authority site which is based around a group of people and the geographical area they live in but am struggling with a domain name. Do I go for an EMD which may be quite long or do I go for a good brandable domain? I'm looking to get quite a bit of content on the site and get visitors through longtail keywords so what do you think? Get the boost of an EMD or go for the brandable name that can be developed and promoted? Thanks.
