I am familiar with this market as my husband is an artist. After doing his research, he has chosen two or three major artist directories online to be listed with. I reviewed your website from the standpoint of an artist like my husband to see what he would gain from listing with you.
First off, your "About Us" materials are pretty vague in regard to what you really do FOR the artist. An example of a vague statement is "By supporting local art show through sponsorship." - do you support one local art show and, if so, is it in New Jersey? What good does that do me in Michigan? You need to focus on what it is that makes Art eXposed different, unique and BETTER than the artist directories / promoters that have been out there longer.
Is there a fee to join as an artist? That needs to be disclosed. If you don't publish your fees, the assumption is you're too expensive.
I don't care for the artist image display on the artist pages - the page reloads when you want to scroll to the next image instead of doing a smooth scroll. Links to artist's websites should open in a new window. When I clicked on an artist link, you just lost me.
From a web developer's standpoint, you are missing valuable content on the home page for the SEs. Your code is missing the most fundamental of attributes for
SEO like ALT tags, summary tags and proper META formatting.
You really need more content overall (artists, NEW news, NEW events) before you start promoting the site. First impression is everything and you don't have enough to invite participation.
