Why It Matters

Your Google rating is your most powerful sales tool

Most people decide whether to trust a business before they even visit your website. Your star rating is the first thing they see.

94% of customers read reviews before buying

A 4.5+ rating increases click-through by 25%

Businesses with 50+ reviews earn 4.6× more revenue

Responding to reviews boosts rating by 0.12 stars on average

Danger zone

Below 4.0

Most customers filter you out automatically. Conversion drops sharply. Competitors with 4.5+ take the click.

Sweet spot

4.5 – 4.9

Customers trust you instantly. You rank higher in Google Maps. More clicks, more calls, more revenue.

Get There Faster

Now you know the number. Here's how to hit it.

Getting reviews doesn't have to be a manual chore. The businesses that collect reviews consistently all do the same things.

01

Ask at the right moment

The best time to ask for a review is immediately after a positive experience — when the feeling is fresh. Waiting even a day cuts response rates dramatically.

02

Make it one click

Send a direct link to your Google review form. Every extra step loses potential reviewers. A QR code, a text message, or a Bragly collection widget makes it effortless.

03

Automate the follow-up

Most happy customers forget to leave a review unless reminded. An automated email or SMS sequence — sent 24 hours after service — is the single biggest lever for volume.
