Drive as much traffic there as you like. Have fun. You are even allowed to invite your fans to post fan videos of your book!
There are a few rules there that I you should read so that everyone has a fair shot at getting the word out about their book. Please feel free to support each other's work by commenting and such. I won't be having too much time to poke around all the time, but beware I do have it set up for spammers. I'll know.
So introduce your book, feature your video, include a link for purchase and roll on and check out others work too. BTW, there are those who don't even have reviews yet, if you have a kindle unlimited membership and they have a great video but no reviews, give em a shot and be kind, take a chance and read their work. and leave them an honest review on Amazon.
This is not meant to be an exchange reading review site.
Amazon frowns on that. In fact, I think it's skating the line too. So, I think it's best that you don't even let the person know you read and reviewed the book. Be a stranger to each other. It's much more helpful and easier to leave and honest review too! Besides, that, be kind to one another. Kisses and talk to you soon.

P.S. It doesn't have to be a long video. It can even be something small like the one I posted on the site!
