Google My Business has updated the directions heatmaps, which they originally launched in 2014 to make them more useful. Allyson Wright, Community Manager of Google My Business, announced it in the Google My Business forums saying "we've made some changes to your directions heatmap, that are rolling out this week." "This update will better allow you to track which areas customers request all forms of directions from, at various zoom levels (post code, city, country)," she added.
In addition, direction requests from some post codes may appear as blank due to user privacy consideration but are included at the city level, she added. Why? Maybe due to GDPR? I am not sure.
Here is the new look at the Google My Business Insights directions heatmap:
You can access yours in the Google My Business dashboard and by clicking on insights.
The help doc says:
Direction requests:This section shows where on the map people request directions to your business. You’ll see your location pinned on the map, and a map that shows the most popular places from which people ask Google Maps for directions to your address. You may also see the total number of requests broken down by city or neighborhood.
On the map, you can zoom in and out on the map using the + and - icons on the bottom-right corner.
