I am thinking of writing a php/MySQL based hyperlink tracker that will allow you to track what URLs you have purchased, where they are located, and if they can still be found on the target website. Ideal for webmasters and SEO specialists. My intention is to design the scripts for you to host on your own servers, or to host a service where you can track your links. I feel that the first solution would be best however, since you do not need to depend on my systems. What I would like to hear is your suggestions you have, and if such a tool would be useful. Here are my own requirements: Track sitewide, blogroll, link page and directory links. Track when a link appears or disappears. Track when a link features a no-follow tag. Details of link expiry and who sold the link. If you have some ideas, please let me know! There will definitely be betas for people to experiment with.
Jago, you can take a look at our links tool here with tracks your purchased links, sold links, link exchanges and friendly links. Have a play around and we can share stuff that works and doesnt work.
