This hub covers how to test variants fairly and how to measure conversion from presell visit to order. * [All example pages](/examples) * [All topics](/topics) ### Measure the sale, not the click The easy number on a presell is click-through to the order page. The number that matters is sales, or revenue, per presell visitor. A curiosity headline can raise clicks and lower sales by sending readers who were never going to buy, so judge every variant on what happens after the click. That means tracking the visitor from presell to order page to order, with the variant and the traffic source attached. ### Split-testing a presell * **Change one thing at a time**: the headline, the lead, the offer placement. Two changes at once tell you nothing about either. * **Split traffic at random** and keep the split stable for each visitor, so a returning reader sees the same version. * **Wait for enough sales** before calling a winner. A dozen orders on each side is noise; decide your stopping rule before the test starts. * **Keep the ad's destination URL the same** where you can. Changing the URL in a live ad can send it back through review and reset the platform's delivery learning. What to test first, how to split traffic, how long to run and when to stop are covered step by step in [landing page split testing for presells](/articles/landing-page-split-testing). ### The numbers to keep per traffic source Presell visitors, click-through to the order page, orders, revenue and refunds, each by variant and by source. The same presell often performs differently on social, native and search traffic, and a blended average hides which source is paying for the test. The full setup, for offer owners and for affiliates who only control the presell, is in [how to measure presell-to-sale conversion by traffic source](/articles/presell-conversion-rate). ### Latest guides [ ](/articles/listicle-landing-page) #### [How to build a listicle presell page that sells without reading like a ranking ](/articles/listicle-landing-page) What a listicle presell is, when it beats a bridge or advertorial, the section order for a reasons-why page, example patterns and the FTC label rules. 13 Oct 2026 [ ](/articles/quiz-funnel) #### [How to build a quiz funnel for paid traffic ](/articles/quiz-funnel) What a quiz funnel is, how to map segments and results, write the first screen to match the ad, pick a quiz funnel builder, track it and keep it compliant. 13 Oct 2026 [ ](/articles/bridge-page-affiliate-marketing) #### [What to put on a bridge page for affiliate offers ](/articles/bridge-page-affiliate-marketing) What a bridge page is in affiliate marketing, the sections to put on one, an annotated example, when it needs presell length, and the mistakes ad networks reject. 13 Oct 2026 [ ](/articles/presell-conversion-rate) #### [How to measure presell-to-sale conversion by traffic source ](/articles/presell-conversion-rate) How to measure presell conversion rate: the events to track, presell to order page conversion, landing page to sale conversion, and how to read it per traffic source. 12 Oct 2026 [ ](/articles/landing-page-split-testing) #### [Landing page split testing for presells: what to test first and when to call it ](/articles/landing-page-split-testing) Landing page split testing for presells and advertorials: what to test first, how to split traffic, how long to run it, sample size, and when to call a winner on EPC. 12 Oct 2026 [ ](/articles/vsl-vs-text-presell) #### [VSL presell or text presell: which one to run first ](/articles/vsl-vs-text-presell) When to start with a text presell and when a VSL presell should go first, how the two stack in one funnel, and how to test the order on EPC. 12 Oct 2026 ### Frequently asked questions What is a good presell conversion rate? There is no number that holds across offers and traffic sources. Compare variants of your own page on sales per visitor rather than against an industry figure. How do I split-test a presell without changing my ad? Use a tool that rotates variants server-side under one URL, so the ad keeps pointing at the same address while visitors are split between versions. How long should a presell test run? Until each variant has enough orders to make the difference meaningful, and over full weeks so weekday and weekend traffic are both included. ### Other topics [AdvertorialsWhat an advertorial is, how a story-led ad page is structured, and complete examples you can copy.](/topics/advertorials) [Presell and bridge pagesHow a presell page is built, the formats it takes (advertorial, listicle, quiz, VSL, bridge) and how it hands the reader to the order page.](/topics/presell-pages) [Direct-response copywritingThe direct-response copy a presell runs on: headlines that select the reader, leads that earn the scroll, offers and guarantees that close.](/topics/direct-response-copywriting) [Compliance and disclosuresHow to label an advertorial, which claims get presells rejected, and what ad networks check on a landing page.](/topics/compliance) [Tools to build presellsWhat to look for in a tool for presells and order pages, and how the common options differ.](/topics/tools) --- [ ](/) Working presell pages, advertorials and order pages you can copy as clean HTML, each with a teardown of why it is built that way, plus guides on direct-response copy, compliance and testing.
