I do tend to keep a close eye on my site statistics and noticed that as of today my images have had a total of exactly 1000 views.
this image, at 94 views, represents almost 10% of the total.
I do realise that views do not automatically equal sales, but on the other hand I do not expect images to be able to sell well if nobody is getting to see them.
What I now need to do is to dramatically increase the size of my portfolio which should increase the views - and also hopefully the sales.
