Shared visitors algorithms

We calculate the proportion of common visitors between two assets to give an idea of the cannibalisation existing between them.

Our shared visitors rates are calculated on the basis of the IDs seen in our databases as having been to two distinct analysed assets.

For addresses and shopping areas, these shared visitors rates take into account both pedestrians and vehicles.

For addresses, our shared visitors rates are calculated at the neighbourhood level, which is the finest granularity to which we can provide this analysis due to GDPR constraints and calculation time.

Also, we apply several adjustments to help us better take into account possible territorial, socio-demographic, allocation and smartphone activity biases.
