I don't know if everyone is making money or what. There are gems in here people and SeoCrab is answering Questions ! Take advantage of this !!
Anyway.. Here is a pretty good question

I have always made Niche websites ( not blogs ) with Silo Structure. I choose EMD+Prefixes or Branding my keyword.
Now, for this journey I will take the blog approach. And my keyword will be mentioned a lot in the articles. I have two options :
1 - Buying Aged Domain ( they don't have any PA or DA ... It has just the old registerer. No idea if Domain Age alone is even useful ) and of course I have no control on the name. But there are some good .com and .net names.
2 - Buy fresh domain. I will have control over the name but I don't know if
www.keywordnews.com/topkeywordtips will be a good idea. having the keyword in the domain name, url, title is over optimizing if you ask me ! So, I might take the brand name approach in this case.
To Conclude, Aged Domain (NO PA, DA, Backlinks) with PMD... OR ... Fresh domain with EMD+prefix ... Or ... Fresh Domain with PMD ( if Aged domain with no weight doesn't worth it )
Note: I am competing in very weak Niche. Less than 30 Competition in Long Tail Pro. So, I guess the only way not to take it is over optimizing my website
