How the scorecards work

Rating is the live Google star average. Review volume is how many customers have rated the company, set against the others on this page. Confidence weighs the rating by that volume, so a 4.9 from hundreds of people carries more weight than a 5.0 from a few dozen. Recency reflects how recently customers are still leaving reviews.

What home security systems cost in Baton Rouge
