We design your website, get you online and then you promote your own business. You can do this through word of mouth, ads in magazines, banner advertisements on forums and places that offer paid banner ads, link exchanges etc. Companies that promise to build you a site that will guarantee traffic and sales are misleading you. This is something you have to work hard at.
As far as search engines finding you, our software system allows you to easily add keywords, meta-titles & meta-descriptions on every page, within every catalog category and with each individual product you ad. All of these help search engines when they crawl your site.
For more information on how to bring traffic to your site, see this helpful article called "Increase Website Traffic"
