I have a 3.5 y/o domain that has the PHP Link Directory script running on it. The script has been on it ever since I bought the domain and I have achieved a fairly good Alexa rank (>30k). The Page Rank is always in flux from a PR4 to PR2 depending on which way the wind blows. I have been on a lot of "top directory" lists and have some decent links coming in. Currently, there are 65k approved links and another 60k pending (I haven't gone through and approved for a few months). I offer $10/yr featured links with TLA and Adsense running, but it doesn't generate more than $100/month. My question is what are some ways I can go about monetizing on the site? Should I try to solicit to the link owners? I'm at a loss. I have been in and out of (white hat) SEO for years, but it seems I can't monetize my own sites. I time has been spent mostly in web development. Any help would be much appreciated.
