A Taxonomy of Web Directory Issues
Web Directories Which Are No Longer Managed
A survey of 79 general-purpose web directories revealed that 62% of those web directories do not appear to be processing submissions.
In many cases, this is because operators of web directory launched their site with great enthusiasm, became overwhelmed by amount of effort required to maintain a web directory, and stopped maintaining their directory. These operators leave their directories online to take advantage of residual advertising revenue, but no longer invest time required to process directory submissions.
Web Directories which Block Search Engine Robots
Some SEO's believe that they can preserve Google PageRank by not giving outbound links from their web sites.
Web directories which operate in this manner will sometimes block Googlebot and other search engine robots from their directory pages using robots.txt or meta tags.
Before submitting to a web directory, check PageRank of directory page upon which you expect your listing to appear. If that page has a PageRank of zero, it could mean that site operator is blocking Googlebot.
However, this same symptom can also mean that site or page is new, and has not been assigned Google PageRank yet. To research this further, examine sites robots.txt file and source code to directory page upon which you expect your listing to appear.
Web Directories which use Scripted Links
Many web directories use scripted links to avoid leaking PageRank. Scripted links use PHP or JavaScript links to redirect user to target page. Although these links work correctly for most site visitors, they do not work for most search engine robots.
To determine if scripted links are in use, place your mouse cursor over an outbound link on directory page upon which you expect to appear. Examine link text which appears in lower left corner of your browser.
