There's a number that changes how your Google listing performs and it's smaller than most people think.
10 reviews.
Before you hit 10, your listing looks like a business that might have closed down last year. After 10, more people click, more people call. Trust jumps.
Here's what makes this worth paying attention to: in most local areas, the majority of businesses never get past a handful of reviews. So getting to 10 quickly puts you ahead of competitors who've been around longer than you.
It's one of the fastest ways to stop looking like a new business — even if you're not.
