I have been having some success with EMDs and I'm wondering how far they can be pushed these days. My current sites are on 3 word EMDs and they were so easy to rank it was ridiculous. I ranked #2 for a buying keyword with my EMD before I even had a single post on my site, only the basic pages like about us, contact us blah blah blah. Can this be done with 4 word EMDs as well? I have a small group of 4 word EMDs for buying keywords that I have my eye on but I wasn't sure how far you could push the benefits of an EMD.
