What local corroboration is, and how it accumulates
The largest component of a location score, the slowest to build, and the one head office cannot produce centrally.
Why it is local rather than brand-level
A system deciding whether to recommend a place near someone weighs evidence attached to that place. Brand-level coverage helps the brand and does comparatively little for a specific branch, which is why a well-known company can have locations nobody recommends.
What accumulates, roughly in order of value
Local editorial coverage. A local paper, a neighbourhood publication, a regional trade outlet. Slow, unbuyable, and the strongest thing available.
Community and civic presence. Chambers, sponsorships, local charity partnerships, event listings. These leave records, and the records are independent by construction.
Local professional listings. Regional bodies, licensing registers, local supplier and partner directories.
Reviews from people in that area. Volume and recency both count, and a long gap reads as a location that stopped.
Mentions by nearby businesses. Frequently overlooked and easy to earn: a partner, a supplier, a neighbouring business that refers work.
What does not count
Brand-level coverage attributed to a location that was not involved. The company own site, including a location page. Paid placement without disclosure. And directory entries created in bulk, which are cheap precisely because they are worth little.
Why head office cannot do it
Every item on the list requires somebody local to be present, to know people, and to do something worth referring to. It is the one part of Multi-Location AI Visibility that cannot be centralised, and it is why the branch manager matters more to this number than the marketing department.
What head office can do
Make it easy: a budget for local sponsorship, a template for a local press approach, permission to speak locally without a sign-off chain, and a way to record what was earned so the next manager does not start from zero. And measure it per location, so effort is visible rather than invisible.
The realistic timescale
Quarters, not weeks. Any offer to accelerate local corroboration substantially should be read carefully, because the mechanisms that produce it quickly are the mechanisms that get discounted for being purchasable.
