I just add a link manager script to my site called Link Department and available for download at http://www.hitcode.com/. The thing that was different was that it converts the results into an html page.
I've read of different things one can do to help search engines spyder a site, but I was wondering what people think about this seemingly major problem with php? I was installing a phpwebsite script for a customer and realized he might take a big hit in his rankings for making the change.
