In this episode of Conversion Rate Optimization with Fexingo, Lucas and Luna dive into a counterintuitive insight: A-B test winners often fade within days of launch. They walk through a real case from a B2B SaaS company that saw a 19 percent lift on day one of a new landing page — only to see it vanish by day seven. The culprit? Recency bias in the test audience. Lucas explains why a seven-day holdout — where part of your audience stays on the original variant after the test ends — is the only way to catch winner degradation before you commit. He shares the specific math: how to size the holdout group (at least 20 percent of your traffic) and what to look for in the first week. Luna pushes back with practical concerns about sample size and timing, and they walk through how one team avoided a costly full rollout by spotting the decay early. This episode is for anyone who runs A-B tests and wants to make sure their winners actually win in the real world.

Episode 64 of Conversion Rate Optimization with Fexingo tackles a frustrating experience: running an A-B test that shows a clear winner, only to have the conversion lift vanish completely after you roll out the winning variant. Lucas and Luna break down the real culprit — regression to the mean in high-traffic experiments — using a concrete example: a media site that tested two article layouts over two weeks. They explain why large sample sizes can actually mask temporary effects, how to spot a 'winner' that's really just noise, and a practical pre-launch validation step that would have saved the team two months of lost revenue. No jargon, just a clear framework for deciding when to trust your test results.

In this episode, Lucas and Luna dive into the power of micro-copy: the tiny words on buttons, form labels, and trust signals that can make or break a conversion. They dissect a specific case from a B2B SaaS company, where changing a button from 'Start Free Trial' to 'See My Custom Demo' increased demo requests by 183 percent. They explore why specificity triggers higher intent, how risk-reversal language works on the subconscious level, and why most A-B tests ignore the one variable that matters most: the copy. Listeners walk away with three concrete micro-copy swaps they can test today. No fluff, just real data from a real test run on a real landing page in Spring 2026.

In this episode, Lucas and Luna dissect a specific email A/B test that lifted conversion by 23 percent—not by changing the offer, design, or call-to-action, but by rewriting a single subject line. They walk through the original line, the winning variant, and the psychological trigger that drove the difference. Luna shares a counter-example from her own inbox where a subject line tanked an otherwise solid campaign, and Lucas explains why personalization tokens can backfire if not tested. They also discuss how to design subject-line tests so the results transfer to other channels like push notifications and SMS. By the end, you'll have a concrete framework for your next email subject-line experiment.

In this episode, Lucas and Luna dig into a real A-B test from a B2B SaaS company that found a 23 percent conversion lift just by changing one word in an email subject line. They walk through the original subject line, the variant, the sample size, the statistical significance, and the surprising reason the change worked—and they discuss why most email subject-line tests fail because they test the wrong thing. If you've ever wondered whether your own subject lines are leaving money on the table, this episode gives you a concrete framework to follow.

Testing subject lines via email sounds easy, but most companies destroy their data by sending at the wrong time, to the wrong segment, or without accounting for recency bias. In this episode, Lucas walks through a concrete case: a B2B SaaS company that ran a 50-50 split on a newsletter subject line — 'Your Monthly Report' vs. 'Your Custom Report Is Ready' — and got radically different open rates depending on whether the test ran on Tuesday morning or Thursday afternoon. He explains why email A-B tests need a holdout group, why you should never test on your entire list at once, and how one marketer accidentally inflated open rates by 18 percent just by sending the same subject line two hours later. Luna challenges the standard '10 percent sample' rule and brings in a counter-example from a DTC brand that learned the hard way that subject line winners don't always lift click-through. By the end, listeners will know how to structure an email A-B test that actually tells them something about their subscribers, not their server clock.

In this episode of Conversion Rate Optimization with Fexingo, Lucas and Luna explore the concept of competitive benchmarking for A-B tests. Using a real-world example from an e-commerce fashion retailer, they discuss how analyzing a competitor's checkout flow led to a 6.7 percent increase in conversion rate. Lucas explains why you shouldn't blindly copy tests and how to adapt insights to your own audience. The episode also covers the ethical considerations of competitive analysis and how to set up a structured benchmarking process.

Episode 58 of Conversion Rate Optimization with Fexingo: Lucas and Luna unpack why running an A-B test without pre-slicing your audience by segment can hide winning and losing variants. Using a real-world example from a mid-market SaaS company, they walk through how a test that showed 'no winner' actually uncovered a 23 percent lift for mobile users and a 9 percent drop for desktop users — completely cancelling each other out. They discuss Simpson's Paradox, the importance of logging device type and referrer source before the test starts, and why post-hoc segmentation is a recipe for false conclusions. A practical, data-focused conversation for anyone running experiments.

Episode 57 of Conversion Rate Optimization with Fexingo digs into a phenomenon that catches many CRO teams off guard: the reversal effect, where a winning variant in an A/B test starts losing after the test is stopped. Lucas and Luna walk through a real case from a mid-market SaaS company that saw a 12% lift during the test, only to watch it vanish within three weeks post-launch. They explain how peeking, early stopping, and behavioral adaptation can inflate false positives, and share a simple fix: extending the validation window with an 'A/A holdout' period. The episode also covers when to trust the reversal as a genuine signal versus statistical noise, and why waiting seven to fourteen days after the test ends before declaring a winner can save teams from rolling back bad decisions. No clickbait, just practical CRO wisdom for marketers who want their test wins to stick.

Episode 56 of Conversion Rate Optimization with Fexingo digs into a common but dangerous mistake: treating all users the same in your A-B tests. Lucas and Luna explain why averaging results across different audience segments — like new vs. returning visitors, mobile vs. desktop, or weekday vs. weekend traffic — can hide a winning variant that actually hurts a key subgroup. Using a real example from a mid-size e-commerce brand, they show how a 12 percent overall lift masked a 7 percent drop among loyal customers. They cover when to segment, why pre-registering your segments beats data dredging, and why a single test might justify multiple rollouts. If you've ever seen a test win overall but feel wrong in your gut, this episode is for you.
