The majority of these 1500+ so called search engines are free links for all pages, very special interest web pages or, even worse, web sites masquerading as search engines.
Submitting your web page to these 1500+ search engines means that you’ll end up with 1500+ spam e-mail messages.
It’s quality that matters, not quantity. For that reason, Miami SEO Guide only submits to search engines that are really used by the majority of web surfers.
