About the International IAB/ABC Spiders & Bots List
The IAB has enlisted The Alliance for Audited Media to perform evaluation and management services associated with maintaining and publishing the industry Spider and Robot list, the use of which is required for compliance to the IAB’s Client Side Counting (CSC) Measurement Guidelines for “double pass” filtering. We have also formed a Spider & Robot Policy Board to oversee and approve list modifications (see list below).

The list will be updated monthly to reflect changes that are brought to the attention of The Alliance for Audited Media, ABC UK, and the Policy Board.

Submit Newly Discovered Spiders & Bots
IAB requests that members submit any new robots they discover as often as possible.
