Reviews decide the map pack and they decide the phone call. Most businesses with genuinely happy customers have a handful of reviews, because asking is awkward and it never becomes anybody's job.
Metcalf Media automates the ask so it happens on every completed job, while the customer still remembers. Anybody who signals they're unhappy is offered a direct line to the owner alongside the public one, so a problem can be put right. Both doors stay open to everybody — routing unhappy customers away from Google is review gating, it breaks Google's own policy, and profiles get penalised for it.
Nothing here involves buying, writing or incentivising a review. Those get detected, they get the listing penalised, and they're not worth the risk.
