Certainly engagement with the fans is key. How much does the likes of ShaymenTV bring into the club ? Long term, i would say making video content free for all fans to see would be beneficial. What's a reasonable guess for the number of shaymenTV subscribers, 500 perhaps? That's £60k a year, but I doubt the club gets the entirety of this money. It's not that much in the scheme of things.
The club has over 700 youtube subscribers. Get lots of video content onto youtube, and engage the fans. It works at other clubs - why not Halifax?
Training out in towards Leeds can't be helping. A local training ground where fans can pop along to watch players train would be beneficial to help make that connection with fans. Let the kids get autographs from the players.
