Market Share Metric

Overview

The Market Share metric tracks changes in your business’s share of foot traffic during your campaign compared to competitors in the same target areas. It helps indicate how your campaign has influenced market share by comparing pre- and post-campaign data.*

*Other factors may contribute to changes in market share during and after a campaign.

Please note that market share considers total visitation across both your locations and your competitors' locations, not just visits generated by GroundTruth media.

Market Share Eligibility

To qualify for the Market Share metric, a campaign must meet the following criteria:

*Standard Industrial Classification (SIC) codes are four-digit numerical codes that categorize industries based on business activities.

How Market Share is Calculated

For eligible campaigns, we display only the directional trend of market share movement. Market Share is calculated at the campaign level after the campaign has run for at least 30 days using the following formula:

For general businesses:

(Visits to tracked POIs in the campaign’s targeted geo) ÷ (Visits to all branded POIs with the same 6-digit SIC code in the campaign’s targeted geo)

For Quick Service Restaurants (QSRs):

(Visits to tracked POIs in the campaign’s targeted geo) ÷ (Visits to branded POIs belonging to select QSR brands in the campaign’s targeted geo)
