Aaron Shepard’s Sales Rank Express is a great tool (mainly for) authors to check the ranking’s of their titles. I checked the current stats to all my books by simply entering my name (only), flipping for format to KINDLE, and selecting “Get Amazon Sales Ranks”
Here is that page output, which you can share on social media.
It’s nice to have a little dashboard to use for yourself.
At the same time, you can also enter in other author information to compare their book rankings if you’re interested in which title to choose to read or, perhaps, if they write comparably to you and in your genre, it is a way for you to see how you do compared to them.
