A method for measuring the average review level of an area

Also available in: Tiếng Việt

Is your venue's 4.4 high or low? You cannot answer that without knowing the area's level. In an area where the median is 4.1, a 4.4 is good; where the median is 4.6, it is below average. Measuring the area takes about 90 credits and one sitting.

The method

Step 1 — define the area and the venue type. Walking radius, same type as yours. Mixing cafes with restaurants produces a meaningless number.

Step 2 — pick six to eight locations. Enough for a median, not so many that it takes a day.

Step 3 — pull reviews for each. Google Maps reviews — 15 credits per run, 200 reviews (10 pages × 20), runs in the background. Six venues is 90 credits.

Step 4 — for each venue calculate three figures: the headline rating, the rating of reviews from the last 12 months, and the number of one and two star reviews in that period.

Step 5 — take the median across the area, for each figure in step 4.

The middle figure in step 4 is the important one. A headline rating pools all history, so a venue under new ownership can carry a score from the previous owner. See what a star rating hides.

Three comparison traps

Mixing venue types. Cafes, restaurants and bars run at very different levels in the same area.

Ignoring review counts. A 4.9 with 12 reviews does not belong in the same table as a 4.3 with 800. Drop venues with fewer than about fifty reviews.

Using the mean instead of the median. One very poor venue drags an area mean down.

What to use the area benchmark for

Setting a realistic goal. "Reach the area median within two quarters" is achievable; "reach 4.8" usually is not.

Knowing where you stand when leasing. See surveying an area with reviews.

Finding the theme the whole area is criticised for. A theme criticised at most venues is an area problem — and if you fix it first, that is a real advantage. See grouping reviews into themes.

Why we do not publish a ready-made table

An area average published today will be wrong within months, and it pools venue types so it is not usable for any specific business. The method does not expire, and the table you measure yourself is true for your exact radius and venue type.

Boundaries to remember

For review authors the tool returns only a display name and the text. No email, no phone number, no profile. Phone numbers exist only for the business itself, because that is its own public line.

Every figure is an estimate from public data the platform displays.

Frequently asked questions

Are six venues enough for a median? Enough for a usable benchmark. Below four you should not conclude.

How often should I repeat it? Quarterly, and before any decision about premises.

Can I run the whole area in one go? No. Each run is one location, up to 200 reviews.
