Adding an AI product-recommendation popup that appeared after 15 seconds of browsing lifted Gelpro Australia's ecommerce conversion rate (purchases) by 27%. OptiMonk ran it for the collagen supplement brand and published it as a case study. The case study does not say how the comparison was made.

## Result

**+27% purchases**

- Ecommerce conversion rate (purchases): +27%.
- The case study headline frames the 27% as a desktop gain, while the body applies it to purchases overall, so the scope is unclear.
- Gelpro also ran a browsing reminder (+4%) and an exit-intent cart reminder (+6%) at the same time. Those are logged as separate results.

## Control

No recommendation popup. Gelpro had been using Klaviyo popups for email capture.

## Variant

A popup with AI product recommendations based on the item being viewed, shown only after 15 seconds of browsing and built to work on mobile.

## Why it likely won (our reading)

- Waiting 15 seconds means the popup reaches people who are browsing, not those who just landed.
- Recommendations tied to the current product help shoppers find a better match in the range.
- Supplement buyers often need help choosing between similar products.

## Caveats

The case study doesn't say whether this was a split test or a before-and-after comparison. Sample size and duration are not shared, other campaigns ran at the same time, and the result is vendor-reported.

## How to run this test

- Hypothesis: If we show a product-recommendation popup based on the item being viewed after 15 seconds of browsing, then purchases will rise because shoppers find a product that fits without searching.
- Primary metric: Ecommerce conversion rate
- Guardrail: Bounce rate
- Guardrail: Average order value
- Guardrail: Mobile conversion rate
- Who should test it: Health and supplement stores with a range of related products. If you sell one hero product, there is little to recommend and the popup may just distract.
