A recent article
describes preliminary results of a survey investigating how artists build, maintain and sell from their websites.
Have a look, it is quite revealing. To perhaps not much surprise, a lot of artists do not sell much, nor do they spend time to update their websites.
If I could have a look at the data behind the results, I would be very interested to know how sales levels corresponded to investment of time and money or both in the website.
I suspect there would be a direct relationship, as the more marketing you do, the more people see your work, the more chances you give yourself to sell. What do you think?
