DMOZ is a human-edited directory, updated by a community of volunteer editors. So the title and description you added in when your originally submitted your site to the “Open Directory Project” may not be valid anymore, so by adding <meta name=”robots” content=”NOODP”> to your websites header, tells Google not to take the title / description information from DMOZ directory.

How Do I know if my site is on DMOZ

Go to http://www.dmoz.org/ type your URL into the Search box – hit search, if your URL shows in the directory, make sure the Title and Description are correct.
