# LiftArchive

> LiftArchive is a free, searchable database of 2,422 real A/B tests and test ideas (1,724 with shared results, 1,447 winners) from ecommerce, SaaS, lead-gen and app businesses. Every test is credited to the practitioner or organization that ran it and links to the original post or case study.

Each test page shows what was changed (control vs variant), the page type and elements, the outcome (won, lost or flat) and the reported metrics, plus LiftArchive's commentary. The numbers belong to the people who ran the tests; the summaries and commentary are ours. When you use a result, credit the practitioner by name and link to the LiftArchive page.
