Many of the articles you read on the Internet regarding search engine optimisation SEO fail to make any distinguishing difference between commercial and noncommercial website listings. What we have found through our own experience . Content it has been said many times but well written content and plenty of it is very important. a Commercial websites with good content often have to take a more active approach in submitting their website to directories and search engines to obtain inbound links. b Noncommercial websites with good content may attract many “natural links” websites that link to yours without a request .
Age we believe that the age of a website is important. a Commercial websites with good content and age will have only succeeded if they have been actively marketed over the years e.g. submissions to directories and other search engines. So having a commercial website that has been around for years is no guarantee that it will come up highly in results. b Noncommercial websites that have good content will have probably picked up many “natural” links over the years. . DMOZ Commercial and Noncommercial websites that have been in this directory for sometime perform better in search engine results.
Why, because the DMOZ directory data is freely distributable and many sites have sprung up over the years cloning part or all of DMOZ. The number of sites using DMOZ data seems to be reducing, therefore if you were in DMOZ at the early stages you are more likely to have many links to your website from many different domain names with no reciprocal links back. A DMOZ listing is still important, but probably not as important as it was years ago when there were fewer directories. Google is still updating its directory with DMOZ data though probably not as frequently as it used to do.
