I have been trying to get some new domains. The thing is almost all .com and .net domains are taken. I have some questions regarding this. 1. Is it necessary to go for EMD's for micro niche sites? 2. If .com and .net domains are taken, should i go for .us or any other domain. Which is the better one from the rest of the list? 3. If the keyword is freehealthadvice and the .com is not available, will it be okay if i go for free-health-advice? A feedback on the subject would be a great help. Thanks.
