Promote National Parks App

I need a results-driven marketer to increase downloads of my National Parks mobile app among outdoor enthusiasts. My priority is to reach hikers, campers, and adventure seekers where they already spend time online, then inspire them to install the app and start exploring.

Here is the focus I have in mind:
• Social media: Craft engaging organic posts and paid ads—especially on Instagram, Facebook, and TikTok—that highlight trail maps, wildlife tips, and trip-planning tools inside the app.
• Search engines: Build and optimise Google Ads and Apple Search Ads that capture intent-based queries such as “best national park guide app” and “offline trail maps”. ASO guidance for the App Store and Google Play is welcome too.
• Influencer partnerships: Identify mid-tier outdoor creators and micro-influencers, negotiate sponsored reels or stories, and track their unique download links to measure ROI.

Please outline your overall approach, expected timeline, and past successes growing app installs in a similar niche. I’m looking for transparent reporting (impressions, CTR, CPI) and actionable suggestions we can iterate on every week.
