Check Retention & LTV: Look at repeat purchases and customer lifetime value. If people don’t come back, the product may be weak.
Collect Feedback: Reviews and direct customer feedback reveal if the product solves the problem.
Analyze Data: Metrics like churn (for apps) or reorders (for consumables like skincare/supplements) show product strength.
Acquisition vs. Retention: Most businesses focus only on acquisition, but retention exposes whether the product truly delivers.
Marketing Stress Test: Running ads aggressively reveals weak points in the funnel product, creative, landing page, or brand.
Real Reviews & PR: Send products to YouTube or micro-reviewers for authentic feedback and exposure.
Holistic View: It’s rarely just the ad or the product it could be landing pages, store design, brand presence, email/SMS marketing, or product-market fit.
Bottom Line: Start marketing hard, track the data, fix holes as they appear. If every hole is unfixable, it’s likely a product problem.
