Today's Internet is all about building links and networks, and without submitting your website to business web directories, you're relying on some page-crawling web bot to do all that work for you. Think about how quickly new websites and pages are generated, and you'll realize that to not submit your website to web directories is a foolish decision that will reduce the chances of your page getting linked to and recognized.
But what kind of web directories should you submit your website to?
There are plenty of options out there, and the important thing to do is remember that you can interpret your website's purpose in as wide a way as possible to suit as many directories as you can find. If your website isn't acceptable for that site, it won't be accepted, but as in many things if you don't try, you'll never reap the benefit of a positive answer.
The worst that can happen is your site won't be listed - the best is that hundreds if not thousands of new visitors will be directed to your site because you've found a great place to list them. This might not happen if you don't reach for as many different interpretations of the content of your site as possible.
The arguments against submitting to a good business web directory might include cost, advertising requirements, or adding links to and from your sites. Like the web rings of old, these elements should be considered and whether or not you choose to include your website on one of these pages should be decided by whether you feel you will reap enough benefit from this particular web directory to offset any issue with the design, layout, and integrity of your site content.
