Guarantee terms

Last updated 4 November 2026

In plain English

Before we start, we screenshot your best ad’s cost per purchase from the last 30 days. That’s the number to beat. When the ads land, you put every ad live in your main campaigns within 7 days, sending traffic to your best-converting landing page at your normal spend. If none of our ads beats your best ad’s cost per purchase by 30 days after delivery, you get a full refund. All we ask is that you get us access, assets and feedback on time. The full terms are in your agreement.

Full terms

These terms apply to the 30-concept package only. They don’t apply to monthly work or ad spend.

1. Start date. Day one is the day all of these are done: payment has cleared, we have read access to your Meta ad account, we have your brand assets and product images, we’ve held the 30-minute onboarding call, and we’ve checked together that your purchase tracking works: purchases reported in Meta (pixel and Conversions API) are within 20% of your store’s orders over the previous 7 days. If they aren’t, we start once that’s fixed.

2. Benchmark. On day one we screenshot the ad in your account with the lowest cost per purchase over the previous 30 days, from Meta Ads Manager on 7-day click, 1-day view. It only counts if it spent at least 3x its own cost per purchase in that window. Sale days (for example Black Friday to Cyber Monday) are left out and the window extends back to fill 30 days.

3. Delivery. We deliver all 30 concepts with 3 hooks each (90 ads) together in Slack, no later than 14 days after day one. If we’re late, the test window moves by the same number of days. If you’re late on feedback or anything we need from you, the delivery date moves by the same number of days.

4. What you do.

• Give feedback on the delivery within 3 business days. No feedback means the ads are approved.
• Put every ad live within 7 days of delivery, as delivered or with edits we agree.
• Send our ads to your best-converting landing page: the page with the lowest cost per purchase in your account over the 30 days before day one (we agree which page it is on the onboarding call). A different page counts only if we agree it in writing.
• Keep the same offer, tracking and attribution setting as the benchmark ad.
• Keep the same bid strategy as the campaign your benchmark ad runs in. Adding or tightening a cost cap, bid cap or ROAS target during the test needs our written agreement.
• Keep your total daily Meta spend at no less than 80% of your average daily spend in the 30 days before day one.
• Keep every ad live for the whole test window. Under ABO, an ad can be paused once it has spent 3x the benchmark cost per purchase without beating it.
• If you use CBO or Advantage+ campaigns, the ads go into the campaign(s) that carry most of your Meta spend, at that campaign’s normal budget, and stay live for the whole test window. Across the test window our ads together must get at least 30% of those campaigns’ spend. If Meta gives them less, run the ABO test below before making a claim.
• If you use ABO, each concept gets its own ad set (its 3 hooks inside) and spends at least 3x the benchmark cost per purchase. Any ad that’s under the benchmark at that point keeps running until it reaches 3x on its own.
• Keep our read access to the ad account until the test ends.

5. Test window. From the day each ad goes live until 30 days after delivery.

6. What counts as a win. Any one of our ads reaches a lower cost per purchase than the benchmark after spending at least 3x the benchmark cost per purchase, on the same attribution setting.

7. Days that don’t count. Days with broken tracking, the site down, the product out of stock, a price or offer change, or the ad account restricted are left out, and the window extends to cover them.

8. Claiming. Claim in writing within 14 days of the test window ending, with an Ads Manager export of every one of our ads showing its launch date, spend, purchases and cost per purchase (7-day click, 1-day view). No export, no claim. We check the numbers from our read access and confirm within 7 days, then pay the refund within 14 days of confirming. The refund is capped at the fee you paid and isn’t available while a chargeback on the same payment is open.

9. After a refund. Your licence to use the ads ends, and any of our ads still running come down within 7 days.

10. If we end it. If we end the engagement for any reason other than non-payment or a breach of these terms, we refund the full fee within 14 days.
