Three jobs: recruit players, win sponsors, and keep families. All three run on the same content engine.
Marketing a girls' football section is three jobs: recruit players, win sponsors, and keep the families you already have. Most clubs treat them as separate campaigns. They are not — all three run on the same content engine.
The matchday graphics that celebrate players are the same graphics that show a sponsor their logo every week. The recruitment graphic is a fixture graphic with different information. One system, three jobs.
Start with the matchday set. It produces the retention content immediately, gives you sponsor placements to sell, and generates the visibility that recruitment depends on.
