Nihalsad sent me a keyword review package several days ago (apologies for taking so long to leave a review). The keywords I received were really, really good. Brilliant in-fact.
They are all easy/relatively easy to rank and in most cases, none of the sites in the top 10 are optimized for the keywords. With the right content and a handful of backlinks, these keywords could definitely rank.
I was given a random keyword package.. and the funny thing is, I'd recently been searching for keywords in this niche myself. I'd found a couple of decent keywords which I thought would be easy to rank, but there weren't enough to build a site around, so I moved on. To my surprise, several of the keywords I'd looked at were there on Nihalsad's list - along with a 20+ other low competition keywords I wasn't able to discover on my own.
All the information is neatly laid out on a spreadsheet and is easy enough to understand, and every metric you'd want to know about is included in his analysis.
Great service. I'd definitely recommend it!
