Frequently Asked Questions

01 What is coupon code leakage?

A discount code intended for one audience — VIPs, influencer followers, win-back lists, employees — gets scraped or shared and applied by shoppers it was never meant for. It's difficult to detect because every leaked redemption still appears in analytics as a normal, successful sale.

02 How much does coupon leakage cost merchants?

Leaked codes erode gross margin by 2–6%. Separately, invalid coupon attempts lower conversion rates by an average of 25% across BrandLock's client base, so leakage damages the discount line and the conversion line simultaneously. Roughly 5% of checkouts involve an invalid or leaked code.

03 How do coupon codes leak?

Four channels. Scraping by aggregator sites (RetailMeNot, Groupon, Slickdeals, VoucherCodes, Dealhack, TopCashback); browser extensions auto-applying segmented codes at checkout; influencer and employee codes reposted publicly; and — newest — AI assistants surfacing codes when shoppers ask. Each requires a different control.

04 Do AI assistants leak coupon codes?

Increasingly, yes. Shoppers now ask ChatGPT, Gemini and Perplexity for discount codes, and those systems retrieve from the same aggregator sites that host scraped codes — including segmented codes never meant to be public. It's a retrieval problem rather than a new leak source, but it widens distribution significantly.

05 How do I find where my coupon codes have leaked?

BrandLock scans 12,000+ coupon aggregator sites, browser extensions and AI channels for your codes, then alerts your team when one appears somewhere unapproved. You see which code, on which site, at what discount, and whether it's controlled or uncontrolled — typically within seconds of a scan.

06 How do I stop coupon code leaks?

Three layers. Detect — monitor where codes surface across aggregators, extensions and AI assistants. Block — prevent extensions injecting codes at checkout. Replace — intercept the shopper with a valid, controlled offer so you keep the sale without the leaked discount. Detection alone doesn't recover margin.

07 Why is my affiliate commission higher than my affiliate-sourced revenue?

Usually last-click attribution being captured by browser extensions rather than genuine referral traffic. An extension firing at checkout registers as the final touch, so the sale is credited to affiliate even though paid, email or organic sourced the visit. Compare affiliate-attributed orders against sessions that had a genuine affiliate landing.

08 Should I just use single-use codes instead?

They stop redistribution but don't solve leakage. Single-use codes prevent one code circulating widely, but they add fulfilment complexity, break for legitimate multi-order customers, and don't address extensions injecting other codes at checkout. They work best combined with detection, not as a replacement for it.

09 How do I stop influencer codes from being reposted publicly?

You mostly can't prevent the repost — you can shorten its useful life. Practical controls: contractual terms with the creator, unique per-creator codes so you can trace the source, expiry windows short enough to limit spread, and monitoring so you know within hours rather than at month-end close.

10 What happens when a shopper enters an invalid code?

Most abandon. A failed promo field is one of the strongest predictors of a lost sale, and it frequently sends the shopper off-site to hunt for a working code — where an extension or aggregator captures the attribution. Serving a valid replacement offer at that moment recovers the order.

You know your codes are leaking. Let's shut it down.
