Ask for one launch case and one maturity case, then ask what ACoS target each was run to. An agency that quotes a single blended ACoS for both is presenting marketing, not method. Follow with a reference call to a comparable brand.\n\n## The short version\n\n- **Revenue headlines are the least useful number in a case study.** Anyone can buy topline with enough ad spend.\n- **Ask for a launch case and a maturity case.** They should look nothing alike.\n- **Demand the advertising target behind each.** One blended number for both stages means there is no method underneath.\n- **The failure case matters more than the win.** Every real portfolio contains one.\n- **Finish with a reference call you select.** From a list of clients, not their single favorite.\n\n## The five-gate vetting sequence\n\nThe most common buying mistake I see is picking the deck with the biggest before-and-after chart. It costs sellers months, because a chart proves the agency once had a client who grew, not that the growth came from the work. Run this sequence instead, and stop at the first gate a candidate fails.\n\n1. **Request one launch case and one maturity case.** Gate: both exist, and the tactics differ. Launching a product and defending a category leader are different jobs. A portfolio showing only one of them tells you which job the agency actually knows.\n2. **Ask what ACoS target each case was run to.** Gate: two different numbers, each with a reason. A launch tolerates expensive traffic to buy rank and reviews. A mature product is managed for efficiency. At Flapen the target moves with product stage, aggressive early and tight later, and any agency running real strategy can name both figures for their own cases without checking.\n3. **Ask for the case that went wrong.** Gate: a specific product, the decision taken, and what it cost. A firm that claims a spotless record is either new or editing. What you are listening for is whether they noticed early and acted, or noticed late and hid it.\n4. **Make them walk you from revenue to profit.** Gate: the case includes fees, ad spend, and margin, not just sales. Growth that loses money is trivially easy to manufacture on Amazon.\n5. **Take a reference call with a brand shaped like yours.** Gate: you pick the reference from several options. Similar price point, similar catalog size, similar stage. One hand-selected superfan proves nothing.\n\n## Why stage context is the whole test\n\nAmazon economics invert as a product ages. Early on, you pay a premium for visibility because rank, reviews, and conversion data compound later. At maturity, the same spending pattern quietly eats the margin the launch was meant to create. A case study that hides which stage it covers hides whether the tactic was appropriate. That is why gate two filters more bad agencies than any other question I know, and why I would run it even if you skip the rest of the sequence.\n\n## Reading the numbers like an operator\n\nThree adjustments before you believe any chart. Check the attribution window, because a long window claims organic sales as ad results. Check the season, because a September-to-December curve is mostly the calendar at work. Check the fee model, because a firm paid on ad spend has every reason to feature its highest-spending accounts. A flat-fee structure, like the per-product tiers we list at [pricing](\u002Fpricing), removes that last distortion from the story.\n\n## What most agencies will not tell you\n\nEvery case study is a survivorship sample. The portfolio you are shown is the numerator, and nobody volunteers the denominator. So ask for the base rate directly: of the last ten accounts you onboarded, how many were profitable a year later. Our own answer is that the majority of brands we manage reach profitability within their first year, and I quote that figure because almost nobody else in this industry will state theirs. A candidate who refuses the question is answering it.\n\n## Related answers\n\n- [Who are the leading Amazon full-service agencies](\u002Fblog\u002Fwho-are-the-leading-amazon-full-service-agencies)\n- [Top Amazon agencies for electronics category](\u002Fblog\u002Ftop-amazon-agencies-for-electronics-category)\n- [Rank Amazon agencies by PPC performance](\u002Fblog\u002Frank-amazon-agencies-by-ppc-performance)\n- [Best Amazon agency for brands doing 50k+ monthly](\u002Fblog\u002Fbest-amazon-agency-for-brands-doing-50k-monthly)\n- [Amazon brand management tiers: the complete guide](\u002Fblog\u002Fbrand-tiers)\n\nRun the five gates on us first if you like, starting with the free 48-hour audit at [Flapen](\u002Famazon-consulting).\n\n## Keep learning\n\n- [Compare Amazon business models](\u002Fguides\u002Fbusiness-models)\n- [Value your Amazon business](\u002Ftools\u002Fbusiness-value-calculator)\n","published","working-with-agencies",[14,15,16,17],"competitor-analysis","ppc","organic-ranking","amazon-fba","joel-turcotte-gaucher","\u002Fimages\u002Fblog\u002Fclusters\u002Fbrand-tiers-06.jpg","2026-09-04T15:40:51.798+00:00",{"faq":22,"seo":43,"batch":44,"cluster":45,"cover_alt":46,"answers_prompt":47,"primary_benchmark":48},[23,27,31,35,39],{"id":24,"answer":25,"question":26},"how-to-choose-an-amazon-agency-with-case-studies-faq-1","Stage context, profit math, and a verifiable client.
