Your reputation is being written without you
Here is the uncomfortable truth most local businesses discover too late: customers are reviewing you constantly, and they don't ask permission first. A one-star review can land on Google at 11pm on a Saturday, sit at the top of your listing all weekend, and be the first thing a hundred prospects read before you've even had coffee on Monday.
Review monitoring is the practice of watching every platform where feedback about you can appear — Google, Facebook, Yelp, industry directories — and being alerted the moment something new shows up. It doesn't change what people write. It changes how fast you know about it, and in reputation, speed is nearly everything.
Think of it as a smoke detector. It doesn't stop fires, but it means you hear about one while it's still a wisp of smoke — not once the whole room is ablaze.
