Web sites need constant promotion. Get out there on every site you can find and talk about your whales. Or get happy customers to mention your site.
Build a mailing list (past customers, friends, visitors) and send them a notice every 2 or 3 months about something new.
Send press releases to local newspapers, your almuni publication, and any other newspaper or magazine that could possibly have an interest in you. Include a photo.
Set up reciprocal links with other toy makers.
Are you near a seacoast? Maybe you could get some gift shops to carry your whales. Add a hangtag that includes your URL.
Your whales are wonderful!
