Google PR Display Mod On OpenLD

06 Jun

Posted by admin as Related Info

I have not yet seen many directories running the OpenLD script, but if you do then here is a Mod that you can add to display the Google PR of your directory listing.

This mod has been contributed by Alex, who owns The Great Directory

Steps to install the Google PR display mod on OpenLD:

Create a folder in “extensions” called “grank” and then put the below text into a “extension.xml” file inside the “grank” folder.

Now go into the admin section and install the extension.

<?xml version=”1.0″ encoding=”UTF-8″?>
<extension>
<id>grank</id>
<title>Google PageRank</title>
<version>0.01</version>
