Link exchanges are time consuming. If you have done few you know what I mean. The trouble is not with arranging them and placing them; you need to maintain them as well. You need to check once in a while to see if the link partners are linking back to you and act accordingly. It gets even more time consuming if the link exchanges are 3 way in which case you have to check a third domain that has your link included. Its hard to keep track of all these, and it gets even harder the more link exchanges that you arrange.
LinkEx takes care of the time consuming parts of link exchanges. As a matter of fact it is fully automated. Potential partners register their domains and linkback URL and you just get a notification of the new link partner. All valid backlinks can be checked with the click of a button from the administrator's area.
The nice thing with LinkEx is that it does not need a database it has a nice admin interface with which you can create unlimited categories among other things. Moreover LinkEx does not require any modifications to the existing site's template/layout. It just assigns a unique URL for each category you create and then you can include the contents (approved partners) into any page you chose to using a php include statement much like this:
<?php include "linkex/data/output/1002" ; ?>
The output formating can be configured per category from the admin interface if one wishes to change the default.
There is some things that I thought would be nice to be included but could not wait for them.
One tweak I had to make on the script was to disable auto-approving for newly registered partners for some high traffic sites I maintain in order to reduce spam links to be displayed in my directory pages for until I got the time to check them personally.
for this all I did was insert this link of php code
if ( !LOGGEDIN ) $link->status = "2"; //inserted this
around line 4251 right before the link-save action. This essentially make the link status suspended to all the links saved by a non logged in person (non admin)
I also advised the robots using the robots.txt in my root folder to not include the directory of LinkEx in their spidering since it would be an easy target to a smart spammer looking for "LinkEx" or equivalent in the search engines
