Variation on the Add Custom Link to Search Result example

I followed the instructions (link below) and got it to work - using the sample metadata file it shows a link to a (fictional) ftp site. So that works. My problem is, I want to do a variation on this example. Instead of the link going to an FTP address, I want it to simply go to a website's URL. I experimented with putting a website's URL in the networkr tag in the sample metadata, but what happens is the "Open" hyperlink disappears from the metadata in the results. So how do I change this example so that instead of the "Open" link working with an FTP address it works with a website's URL? It sounds like it should not be that difficult but I can't get it to work.
