# Bidder Funnel reporting

Reporting can now be viewed as a Bidder Funnel as well as the existing Auction Funnel.

Auction Funnel counts one row per ad request, so a bidder only appears once it has won. Bidder Funnel splits the same auctions by the bidders they called, adding the denominators that were missing.

## What’s new

- Bid requests: See how often each bidder was asked to bid.
- Responses: See how often each bidder responded.
- Losing bids: See what a bidder bid when it lost.
- Breakdowns: Split the funnel by app, bidder, ad format, OS, country, priority, ad unit, round, bid outcome, and SDK error.

## Getting started

On the Reporting page, open the report heading above the date controls and switch to Bidder Funnel. Read the [reporting docs](https://docs.cloudx.io/en/dashboard/reporting) for every metric.
