Free vs Paid directory submission

Submitting your website to directories is a great way to increase your Google page rank and high page rank will result in better placement for your website, more visitors and more sales. Knowing that, you would probably want to add your site to as many directories as possible but there is one last thing to take into consideration before you start: Which is better paid or free directories?
Although the word “free” can be very tempting you should know that submitting your website to a free directory can be a really frustrating experience. Such directories are often very poorly maintained and it could take months to get your site listed. Many of these so called free directories are also full of spam and MFA (made for advertising) websites.
In contrast, a paid directory will review your site in days and you can be sure that it won’t end up surrounded by worthless spam sites. Keep in mind that the webmasters of these directories have paid thousands of dollars to promote them and get high page rank which will eventually result in higher rank for your website too. Even a single link in a site like Totalposters for example can boost your PR significantly in a very short time.
In conclusion, submitting your site to free directories won’t hurt you but if you are looking for fast results and you want things to be done professionally and in a timely manner then I suggest you spare a few dollars and join some of the better paid directories.
