Please Note:
I had received a free review copy from OP in exchange for a written feedback, so this is it:
----------------------------
My Feedback on the review package I received from OP:
I simply want to say that the review package I received is "AMAZING and extremely powerful", in the sense that OP has covered keywords from many top niches and he gives lots and lots of quality keywords in every niche. There are even many sub-niches which has carefully chosen keywords in those sub-niches. Everything is nicely grouped in categories, and it is easy to find the niches, and the keywords that are included in them.
I am presently working on a Amazon aff website, and I had spent countless hours in find low comp high volume keywords in the niche/sub-niches I am working on. So I checked those sub-niche kws provided by OP, and I was pleasantly surprised to find many new quality keywords which had skipped my earlier work done using LTP! I checked many of those new keywords (which were not on my earlier self-researched KW list) and many among them were really low comp high volume keywords which will now make my own research much richer!

In that sense, I have already gained from this package in actually the first hour or less time of receiving it!
Regarding the footprints included in the package:
There are 7 main groups of footprints, and they (each group) has extremely large numbers of quality footprints included in them!
OP has put in a marvelous work for anyone who needs to do proper research on keywords. Afte reading about them, I am using some of the footprints in my Scrapebox, and am finding a lot of good and related sites to get some good back-links for my upcoming affiliate site.
All in All:
A really very high quality compilation of some of the very high-quality, and very useful KWs and SEO-related (ideal for getting quality backlinks) stuff that I can use in my KW and SEO research and implementation. I know that this package will be useful to me again and again in my ongoing work on my and other clients' websites. So this package will definitely occupy a prominent space on my HDD, a space where all my reference guides and sw are placed for easy finding and when required! The package simply demands that kind of respect imo.
Because of the greatly useful content of this package, which includes numerous keywords grouped in carefully selected categories and its niches and sub-niches, and the numbers are simply overwhelming, I think that you simply need to see it for yourself to understand how high quality the entire work is! There are real gem of keywords and phrases in most of those files!
I haven't even gone through all those files yet, and I am already impressed!
As I am slogging in my own KWs and SEO related ongoing work preparing my Amazon related site, this review package has come to me at a right time, and it will definitely help me. So "Thank you very much" to OP!
To those who are still learning about scraping and such tools, a step by step type of guide on scraping will definitely help you imo.
My opinion:
5-Star value, and recommended 100%

.
God bless, Regards!
I find this package this much useful, and so thanks a lot to the OP for providing me with his great compilation, and allowing me to check its utility value for his potential customers.
To them (the potential customers), I can only say that I have found this package is of amazingly high quality, and a lot more worthy for the money they will use to buy it! I recommend this 100%, and would like to say that this is a 5-Star positive package and I wish OP every success in this venture!
