Offline Attribution




Choozle’s offline attribution solution, powered by Foursquare, allows advertisers to tie their advertising efforts to real-world foot traffic directly. By leveraging extensive, highly-accurate mobile location data from billions of devices across the globe, you can now measure the impact of your Choozle campaigns on in-store visits.

Offline Attribution Overview Document

As a result of the recent privacy legislation in Virginia, Connecticut, and Washington, our ability to execute geoframing or offline attribution within these states has been restricted. While real-time geofencing remains an option, functionalities such as targeting with a lookback window and tracking offline visit feeds are no longer viable in these regions.

Key Benefits

Bridge the gap between digital and physical. Not all final conversions take place online. Form fills, and website visits can provide a great top of funnel lead generation, but if your goal is to increase customer visits to your location, offline attribution provides a clear picture of which channels and tactics are truly driving incremental in-store visits.

Measure in real-time with the highest quality data. Foursquare’s first-party, always-on panel of devices is the largest in the industry. They consistently follow your customer’s journey with millions of updates from the trusted app SDK partners and user communities. 

Stretch your investment. With real-time reporting, you’ll be able to reallocate your spending based on what’s driving visit-lift most efficiently for your campaign. With a better understanding of which tactics are most effective in driving foot traffic, you can further optimize your current campaign and inform future media plans to provide higher returns on your ad spend.

Offline attribution measurement is only available for campaigns with a minimum duration of 2 months and 1 million impressions per month across at least 10 locations. Offline attribution is available globally except for EMEA (due to GDPR) and China, North Korea, and South Korea within APAC. Foursquare does not measure hospitals or doctors’ offices.


About Foursquare’s Visit Methodology

First-party Data Advantage

Rather than an arbitrary geo-fence, Foursquare uses their Place Shapes (130M venues) unique to each venue in their database based and formed using confirmed visits (human verification) from their first-party users. The shape is formed based on each user's location when the visit to that location is confirmed (i.e., check-in, survey response from panel apps, confirmed SDK visit from apps that leverage their SDK, etc.). That shape is a unique per venue and is constantly updated as more visits occur. Once formed, in addition to confirmed visits within their apps, they include API calls from apps leveraging their API for location services to keep the venue shapes refreshed multiple times a day.


Defining a Visit

  • Signals used. GPS is used in combination with wifi and accelerometer (as well as Bluetooth and beacons), with WiFi being a strong signal for reliability, especially for dense areas like urban centers, malls, airports, etc. The accelerometer is key to confirm dwell time in the location, as a visit is only counted if a person stays for at least 3 minutes within the place shape. 
  • Start with understanding what the venue looks like to the mobile phone. Each POI on Foursquare's map is a unique thumbprint of a venue based on the signals mapped there by a mobile device, including over 14B consumer check-ins.  When a user enters a place shape and dwells for at least 3 minutes, Foursquare's Pilgrim background technology records all of the 7+ signals available on the phone, match them to confirmed signals from check-ins overtime for that Place Shape, and passively registers a visit.
  • Stop detection & dwell time. Foursquare defines a visit as a smartphone stopping for at least 3 minutes within a Place Shape (their map of the world). Foursquare will snap them passively to a venue when all the phone signals match with Foursquare's verified signals with a 90% degree of confidence.  They use Stop Detection to understand when the user stops moving, as defined by the exponential moving average of their velocity going below a threshold value of 0.2 meters/second. The visit ends when the user has moved more than 100m from the location of the arrival. All visits are mapped to their proprietary location map


Trusted by premium tech companies

Foursquare’s API venue map is leveraged by over 150,000 apps, including Apple (places of interest in Apple Maps globally), Uber (venue lookup/pick up), Samsung (Points of interest added to photos), Snapchat (geo-filters), Twitter (geotagging of tweets) and more. 


MRC Accredited

Foursquare is the ONLY location company to have their visit methodology accredited by the MRC. This took years of auditing and investment


How to Get Started

Offline Attribution is a part of Choozle’s  Supported Solutions and can be implemented with the help of our Client Experience team and is available for any campaign type in Choozle for an additional $1 CPM. To unlock and access Offline Attribution, please contact your Account Manager or our Support Center team  for assistance and more information.

As part of Choozle’s Supported Solutions, you will need to provide the campaign details (Advertiser, Flight dates, Budget/Goal, List of locations you’d like to measure). Once we receive this information, Foursquare pixels will be added manually to your campaign as a conversion event on the backend by a Choozle representative.

Please note: It can require up to 1 week for the pixel to apply to your campaign. The conversion event will not show in your campaign settings in Choozle, and any changes made to the campaign settings in the Choozle platform will cause the pixel to fall off mid-flight. All conversion data will be available in all standard reports.
