Hi JonS, Welcome!
I have to tell you that your numbers are impressive. What is best is the 23k on the list. This is the key to promote to your advertisers.
Yes, your visits and page views are great. Of course, I haven't looked at the site. You have several options. If your subscribers consider you a good and credible source of information and consider you an 'expert', you have what I would consider a 'gold mine'.
I really don't want to detail things that I would suggest in this public forum because they took years and several thousand dollars of trial and error to figure out.
If you want, feel free to PM me and we can talk in more detail.
Hope to hear from you soon. Good luck!
