Directories
These are similar to search engines but instead of relying on automatic algorithms, directories have actual human beings checking websites! Yahoo!, The Open Directory Project and JoeAnt are all human edited directories.

The main difference with directories over search engines is that directories only list the home page and the information they file for your site is either the information you give them via your submission, or a description written by a directory editor.

The 2 most important directories to submit to are;
Yahoo! - http://dir.yahoo.com/ (Costs $299 for commercial sites)
The Open Directory Project - http://www.dmoz.org (Free)

DO NOT submit more than once during a 3 month period, and do not submit one website to multiple categories. Read the submission guidelines for each site if you're unsure about anything.

PPC

PPC ads appear like search engine listings but are actually paid advertisements. The highest bidder gets the highest position. Yahoo, Google Adwords and Miva are all examples of PPC engines that you can join. The advantages are that you can get a Number 1 listing almost immediately, the disadvantage is that you have to pay for every click through.

Google AdWords is not strictly a PPC Engine but it is usually lumped in with the others as you still have to pay for each click you receive.

How do you get visitors to your site?

The most popular method of attracting new visitors is by ranking well in search engines such as Google, MSN or Yahoo!. Search engines use algorithms to automatically rank sites, these algorithms look at many different elements of a webpage such as meta tags, content and the number of other websites linking to your own.

The most important step is to research the keyphrases that visitors will use to find sites like yours. You can find phrases that people are using by visiting the Overture keyword suggestion tool here - http://inventory.overture.com/d/searchinventory/suggestion/,

and by visiting Word Tracker here -

Simply brainstorm a list of every possible phrase that you think a searcher might use to find your site or the products you're promoting. Check your site logs too and see what users are already using.

You also need to add meta tags to each page on your website, if you haven't already. These meta tags go within the here section of your site and should look like this;
