How do you measure whether a rebrand improved perception?

You measure it by asking people who walk in whether they recognise the venue and whether the door matches what they expected, not with a survey of “do you like the logo?”. If new reviews describe the same trade with fewer doubts, perception moved. Keep ten reviews from before and, a month on, ten from after, and underline the words they use for the place. Add how many people still ask for the old name. Success is declared on the day of the post and nobody checks whether reception is still explaining that “we used to be someone else”. The new brand has not reached the floor's sentence.

At four weeks there is a note: words from the reviews, questions at the door, and whether avatar, sign and menu match. That note says whether the change is perceived or only printed.
