Hi,
I'd suggest that you start working on your SEO /search engine optimisation/. One of the most important tips for that are:
*100% valid code on all pages
*A lot of original content
*Incoming links to your site
*Listing on directories - Yahoo!, Google/DMOZ.org, MSN
*A lot of keywords per page, relevant to your domain name, headings (h1, h2) and title of the page
Misc tips on SEO:
*Don't pay for it - SE (search engine) algorythms are changing so fast that the moment you pay for it you will have to pay for it again.
*Don't do Hyper Optimisation - take your time, don't spend on it more than a hour or two per day. The more often the updates on your site, the better the ranking on SERPs (Search Engine Result Pages).
*Don't rely 100% on it - good SEO can take more than a year to accomplish as you need high PR (page rank), domain popularity, relevant sites (one citing your content) and so on.
*Play fair! - the so called Blackhat SEO techniques can get you banned for nothing. Never use them.
By my judgment that is the real handy work a site should have for popularity. You can also do some offline advertising such as: leaving sticker with a catchy phrase and the address on walls (a classic, but might litter the area if you are pressing it too much), have the name of your site on your car, make stickers for cars and ask friends and relatives to use them, posters, billboards (much more effective than some PPC /pay per click/ advertisements.
Hope this helps! Good luck.
