Most Shopify sellers lose money on ads not because their product is wrong, but because they skipped the research step that costs nothing. The standard advice — start with $5 to $10 per day on a single platform, test audiences, learn before you scale— is real and useful. Their winning ads are sitting in an intelligence database right now, sortable by engagement, filterable by country, searchable by the exact keywords you’re targeting. They treat their $5–$ 10daily test budget as a discovery budget — finding what works from scratch — when it could be a confirmation budget, verifying what competitor data already suggests. You burn budget on creative directions that someone else already proved wrong six months ago.
