If you're targeting a low comp keyword with a small niche site go for EMD, if you can't get it go for PMD.
Could be in certain circumstances but I wouldn't recommend it. Build a brand and you'll get more authority from search engines. Google laid down the hammer on a lot of EMD sites over the past few years
Hi, can you tell us a bit more on how you build your links? Is it relatively easy to rank it? thank you.EMD works. I currently rank #1 with sitelinks for a very competitive keyword above amazon. What happens is, if you do it right, google will think the generic word is your brand so you will be cemented on position 1 with no fluctuations ever.
