It's rarely the product itself that sells. It is the concept(or story) behind the product that sells.
A professor-friend of mine took a challenge from his class. The challenge was to profit from selling sand in Sahara.
So he went to Cairo, dug up loads of sand, washed it and sold it as "silica" for 3 months.
By changing the concept, he was able to sell to the locals the impossible and make a profit.
A website is a service. To promote any service business, even a restaurant, one has to 'get out there and promote'. Even if it means passing out cool flyers on the street, dressed as your website. Yahoo actually did that many years ago in the US.
Host themed events. Show up at convention/expos etc. Make a T-shit with the logo and pay a street comedian to wear it during a performance. Make people curious.
