I need a results-oriented marketer who can scale an Android + iOS e-commerce app in Sri Lanka. The goal is straightforward: drive a steady stream of genuine installs and convert those installs into in-app purchases. Social media will be our primary battlefield. campaigns on Facebook, Instagram, and TikTok, leveraging each platform’s ad manager to hit purchasers, look-alikes, and retargeting pools. Every new user must be real—no incentivised traffic, no bots—because in-app revenue is how we will judge success. What I expect from you • A clear launch strategy tailored to Sri Lankan audiences, including creative angles, ad formats, and bidding tactics. • Hands-on setup and daily optimisation inside Facebook Ads Manager, Instagram placement controls, and TikTok Ads. • Conversion-tracking that maps installs to purchase events so we can see ROAS in black and white. • Weekly reports detailing spend, installs, purchase volume, cost per purchase, and the next optimisation moves. Acceptance criteria 1. All installs verifiably originate from Sri Lanka (Google Play Console / App Store Connect data). 2. A measurable uplift in first-week purchase rate—targets and benchmarks agreed before launch. 3. Transparent ad account access so I can view performance at any time. You will be free to suggest creative assets or influencer tie-ins if they support the paid social plan, but social ads remain the core channel. If this matches your skill set and you’re confident you can turn installs into real sales, let’s talk and get campaigns live quickly.
