I have been searching for a link exchange script to add to my site with terrible luck. Can you recommend a link exchange script that can be integrated within my site?
I would never recommend using a link exchange script. Despite the hype, there is no short cut to link building and reciprocal link exchanges rarely add any value to your site.
I can also highly recommend all the tactics described by the link building rockstars in Pole Positions e-book Link Building Secrets.
