I have it since released and nothing really ever changed with the tool although you can see update (new version) every few months
Basically VMB scrapes YouTube and give you everything, desc, titles and tags are based on what is used the most and not very relevant
For example: if you want to target 1 main keyword, you will get stupid desc and stupid tag set for your kw because tool chooses kws with the most repetition
Niche Analysis might be of some value (joke), if you care to watch at other video stats which is automatically wrong because some videos were ranked under old YT algo, some under NEW, and in general you have so many factors that applies, so Vid IQ or any tool to give you proper analysis is actually a garbage, but you know what, these companies are making money, so they care to market their stuff
Everything you need to rank and bank is to get interested in your niche, learn and scan manually everything about it, and that's it, no software beats your brain
Don't buy it
