I received a free copy of this service in exchange for a review.
I just checked the report in detail, I looked at all aspects of the report, the website and also checked things out myself using Ahrefs as well as some manual investigation.
The short summary: This is a cool service and it's pretty much a) exactly what I have done myself with great success so I know it works and b) it's pretty much what I tell other people to do if and when they ask me for SEO and amazon affiliate site advice.
Keyword research is arguably the most important part of any affiliate site as it acts as the foundation for all of the following steps and this service pretty much gives you the perfect keyword research in a box because what you are getting is the details of a ranking website that has loads of top-ranking keywords but at the same time one that has a very weak link profile. You don't just get the URL of this site, you get reports detailing all of the specific keywords it is ranking for, domains that link to it and the top-ranking pages for the domain.
If you want a lucrative niche delivered to you on a silver plate, this is as close as you will get.
All you have to do then is build your website, target the same niche and even the same individual keywords, write something longer and more comprehensive than what they have written themselves and then build some decent links over the course of a few months. With a bit of luck, you will be ranking that bad-boy in no time at all.
Top marks from me, and the report that I received as part of this review is going into my "to-do" SEO projects folder and will be the next one on my list.
