I remember Accrington giving a shirt to all kids of a certain age to encourage support, possibly a match ticket as well? Could the club do something similar? A fair chunk of football support comes from a family member/friend dragging someone along, proactively targeting fans could maybe help (especially in a city like Cardiff)

There's also a large student population, could we offer tickets through the students union for instance? Cardiff Uni alone has about 30,000 students. From memory a fair bit of Cardiff Uni's marketing is about how special Cardiff/Wales is, could tie in with that
