Prove a fix worked

Verified lift: how a change is measured, what each verdict means and how long it takes.

• Find out whether a fix workedProof compares the answers each change should move with answers it could not have touched, so you can see whether the change itself made AI assistants name you more often. LegitGeo calls a clear rise verified lift.
• What each verdict meansHow to read Verified, Probably helped, No effect found, Went down and Not proven, the range under the number, and a line such as “98% sure this fix helped”.
• How long a verdict takes, and what you see meanwhileA verdict arrives about 31 days after a change goes live, after three days for assistants to re-read your pages and four weeks of new answers, and until then Proof shows an interim reading.
• Log a change you madeRecord a change you made outside LegitGeo, such as new prices on your site or an updated listing, so Proof can measure whether it moved AI answers.
• Plan a change before you make itChoose the questions and assistants a change should move before you make it, then mark it live on the day, so nobody can pick the questions that happened to go up afterwards.
• Leave a change out of measurementStop measuring a change that never happened, was logged by mistake or was undone, and bring it back later if you need to.
