I have always found the opposite of PJ.  My number of views and the number of watchers directly correlates with sales overtime. 

 

Not sure of simple solutions regarding this.

 

I use inkfrog to list, and in addition to a quicker listing process and photo hosting service, it provides me with real-time and over-time reporting view and sales data and excludes my ISP address from all counts, but it comes with a monthly fee of about $15. You would need to have a decent turnover and a more on-going commitment to increasing your sales, to make it worth your while IMO.   For me its worth every cent I pay, but for others it would be a big waste of money.
