Parallelize bid requests

Overview

This audit checks whether or not header bidding requests are being made sequentially. In most cases, these requests are not dependent on one another and can be made in parallel to speed up ad loading.

Recommendations

Issue header bidding requests in parallel, rather than sequentially. If you're using a header bidding library, the library documentation may have recommendations on how to do this.

The list of supported ad exchanges and supply side platforms this audit evaluates can be found in our GitHub repository.
