Welcome to the second post in my series where I review the various programs I have used during my KDP low-content book publishing journey. So far, I’ve reviewed Book Bolt, and today I am going to review Publisher Rocket
(If you aren’t sure what I’m talking about, you can check out my first post on creating KDP low-content books here, as well as my update post, here.)
I didn’t download Publisher Rocket specifically for creating low-content books, as I had already purchased it previously for another project. But I was glad to have it on hand and I have found it helpful and easy to use.
What is Publisher Rocket?
For those who don’t know, Publisher Rocket is a research tool specifically designed to help authors find the best Amazon keywords for their books. You put in your keyword and it will show you how competitive it is along with a bunch of other useful information.
Once you’ve found competitive keywords, you can use them in your title, subtitle, or keyword boxes on Amazon.
You can also use Publisher Rocket to help you find the best categories to list your book in.
The pros and cons
Publisher Rocket is a straightforward keyword research tool, with easy-to-understand results. I prefer this program to Book Bolt for keywords specifically, and I felt that the layout of the results, and the depth of information that you get were both superior with Publisher Rocket. Also, sometimes keywords that I would search for on Book Bolt would return with “no data” in some fields, but I’ve never had that problem with Publisher Rocket.
In addition to keyword research, Publisher Rocket can be used to help you chose your Amazon categories, evaluate your competition and find the best keywords for Amazon ads. After searching for a keyword, you can see what competitors are ranking for that keyword, their estimated sales, and Best Sellers Rank (BSR). All of these features work well, with clear results and an easy-to-understand interface
The only real con of Publisher Rocket that I have seen so far is the high upfront cost. Currently, it is a $97 one-time purchase, and you will get access for life. If you are working on an ultra-tight budget then you may decide it’s best to wait to purchase it until you know if selling books on Amazon is something you want to stick with.
Who is it best for?
I would recommend Publisher Rocket to people who want to go deeper with their KDP keyword research than they can through Book Bolt or free resources. I would especially recommend Publisher Rocket for those who want to self-publish “regular” books, whether that be nonfiction, poetry, fiction, essay collections, etc.
If you can afford the investment and you know self-publishing is something you would like to pursue (either low-content books or otherwise) I think that Publisher Rocket is worth the money.
But if you want to pursue publishing on Amazon and really can’t afford it, there are cheaper or free alternatives. Never feel like you have to spend more than you are able in order to do this!
Would I buy again?
If I were needing to make the choice again right this moment, I honestly wouldn’t be able to afford the $97. I bought it at a time when I felt that I could. That being said, I am glad that I bought it when I did and I would buy it again if I felt I could safely spend the money.
