The Leads.txt file is a simple text file that contains a list of authorized leads, along with their corresponding IDs and timestamps. Here's an example of what a Leads.txt file might look like:
# leads.txt account_id_1 lead_id_1 2022-01-01T00:00:00Z account_id_2 lead_id_2 2022-01-01T00:00:00Z In this example, the Leads.txt file lists two authorized leads, each identified by a unique account ID and lead ID. The timestamp indicates when the lead was authorized.
The adoption of Leads.txt has been growing steadily since its introduction in 2018. Many major publishers, ad exchanges, and supply-side platforms (SSPs) have implemented Leads.txt as part of their digital advertising operations. The IAB Tech Lab provides guidelines and tools to help publishers and ad industry participants implement Leads.txt effectively.
