THE MEANING OF 'LULU SALES RANK'

May you help me answer these two questions, when I shop eBooks on lulu.com I see the words ‘Lulu sales rank’ followed by a numerical number which changes from time to time. What is the meaning of ‘Lulu sales rank’? And why does it change from time to time?Thank you! Poor Romance; Poor Adult
