Here are some tips to help you with you promoting your site :

1. Use different meta keywords and meta description for categories, custom pages and general pages. Make the distinction between meta keywords and meta description: meta keywords is a list of keywords separated by comma, and meta description is a natural description of the page content. It is important that these are different for each page. If you don't know these seo concepts make a google search on "seo" and you will find many sites that explain these concepts.

2. Enable Add Meta info with listings option from Settings/ Listing Settings section, which will permit adding meta information for each listing when posting it. If this option is Off, meta information will be automatically generated from the ad content.

3. Use Sitemap feature from the script and add a site sitemap to Google. See the script manual for more details.

4. Make an account to feedburner.com and add your RSS feed there. Also see the script manual for more details.

5. Add your site to free directories that you can find, forums or any other sites. Use in your site description keywords that you want to promote your site for.

6. Consider using a paid system like Google Adwords to promote your site.

7. Consider adding a blog where you can write articles periodically, if you have the possibility. Search engine will index your blog content and send you more visitors for many different keywords.

8. Google Analytics is a tool that will help you track where your traffic comes from.
