What should athletes do to promote sponsors on social media beyond just announcing the partnership?

Don't just post one announcement saying 'check them out' and never mention them again. Instead: 1) Continue creating content featuring their products throughout the year, 2) Be specific with calls to action - direct people to the right retailer, website, or use affiliate links, 3) Show authentic product use and explain WHY you use it, 4) Help with their specific marketing initiatives (like NGK's ShopSquad program), 5) Collect and share data with sponsors showing impressions, engagement, video views, and link clicks from your promotional posts, 6) Create content they can repurpose for their own channels. Conduct surveys of your audience to gather demographic data and identify problems your sponsors' products can solve.
