A/B TestingUsing the Builder

Test Lifecycle

Each A/B test moves through four statuses. The header pill in the builder shows where you are. What visitors see at https://myflo.link/yourname depends on both page publish state and test status.

Status → public behavior

StatusHeader pillBuilderPublic visitors (published page)
DraftDraftEdit variants A / B, set traffic, then Start testNormal live page — variant edits are not shown
RunningLiveMonitor Results, pause, declare winner, or end — variant blocks and page settings are locked (pause to edit)Traffic split to variants (cookie keeps returning visitors on the same variant)
PausedPausedEdit variants again; Resume, declare winner, or endNormal live page again until you resume
Completed(test closed)Single-page editing; Update live after a winner if neededLive page (winning variant promoted if you declared a winner)

Builder preview vs live page

The multi-variant canvas in the builder always shows your draft, live, or paused test. View live preview opens your public URL — visitors only see variants while the test is Live (running).

Typical flow

  1. Draft — create test, edit variants, set traffic to 100%.
  2. Start testLive — measurement begins; public assignment starts.
  3. Pause (optional) — stop new variant traffic; visitors see the live page. Pause is also required before editing variant content while a test was live.
  4. Resume → back to Live (Flo saves any pending variant edits first), or Declare winner / End test without winnerCompleted.
