One way to get your website noticed, although not as popular these days anymore, is to get it listed in the web directories, which are indexes to various places on the web. It's important to be familiar with the various directories to ensure that you get a healthy return in terms or traffic form them; some directories are simply not worth your bother.
Most sites organize their index by category or subject as finding anything alphabetically would be next to impossible. Submitting your site is a piece of cake! Just find the "add your link" blurb (or something of the like) and follow the directions. You should be able to submit free of charge to most sites, but it's not uncommon to find sites that charge for submissions. There are some sites such as Yahoo and Lycos that offer free inclusion but also give you the option of express inclusion for a small fee, which gets your site into the index faster.
So, where should you obtain web directory listings? Here's a list of the most popular search engines where you should submit your website to.
One of the most important goals is to get indexed in Google, as it is responsible for about 80% of all search engine traffic. While most search engines require you to submit your links, Google likes to find your site in a more natural way by following links. In order to increase your chance of getting into Google's web directory listing, instead of submitting every single page of your site, be sure to link them up properly within the site as well as from outside sources. The more links, the better as long as they are from reliable sources; avoid link farms at all costs.
