Another source of traffic: directory submission

Incoming links play an integral role in search engine rankings and thus should be taken into consideration by web masters. A lot of web masters opt to "trade" links with other web sites to gain these links. This can be quite effective, provided the sites they trade with are related in some way to their site.

Getting quality links can be a bit of a challenge, The reason is: search engine spiders have been programmed to ignore links on a site that are not relevant to the site. That's why it's so important to get good quality links, if you choose to do link exchange
The benefits of directory submission are to ensure quality links, which is why it's best to go with directory submission. Directory submission allows you to quickly and easily get good incoming links to your site. These links are followed by the spider and almost never ignored. All you need to do is simply submit your website to the directory and you're done.
