We have CIAN - an aggregator of real estate ads and similar services. In them, we filter the search by the cost of houses and we receive a list with addresses. Instead of the existing tool, you can use any other list - for example, addresses:
Points - houses whose price is higher than 400,000,000 rubles
It writes down all the addresses and adds them to the geo-encoder, which translates these addresses into coordinates. We send them to advertising platforms. Usually, there can be several thousand such addresses, because of this, ordinary mortal marketers cannot perform this, but ours can.
We split the received customers by sales channel and saw that ARPU and average receipt from these types of advertising campaigns are higher than from similar ones made by standard geotargeting.
