Recently a contemporary artist friend who is new to promoting her art on the internet said she was hearing conflicting advice about what makes a good artist's website. "Some people are telling me I should keep it very spare," she said, "with little text and mostly images of my art. And that galleries do not like to see prices on an artist's website."
It is true, I told her, that galleries do not like it when artists publish their prices on the internet. So if your main purpose in having a website is to attract galleries, then leave the prices off. Galleries in New York and Los Angeles pay higher rents than galleries in small-town, USA, and therefore need to charge higher prices for the art they sell. They may also take a larger percentage of the retail price for this same reason.
Once you publish a price on the internet, it would be hard for a gallery to charge more for the same painting, or even a different painting of the same size by the same artist. The internet is a great leveler, and more collectors are Googling art and artists, rather than relying completely on a gallery director or designer to tell them what to buy and at what price.
If your main objective is to sell your art through galleries, then your website should provide a showcase for the art along with your credentials, exhibition history, statement, and reviews. Think of it as an online portfolio. You'll want to use your internet presence to help your present galleries sell your art, and to help you find new gallery representation.
