How real-time call bidding works

Real-time call bidding is a live auction for a single phone call. When someone calls your tracking number, the platform asks every eligible buyer what they will pay for that caller, picks the highest bid above your minimum, and connects the call — all while the caller waits a moment on the line. Instead of every call going to the same buyer at the same fixed price, each call goes to the buyer who values it most right now.

Why bid on calls at all?

Not every call is worth the same. A caller from one state, at one time of day, asking about one product can be worth far more to a buyer than another caller on the same campaign. A fixed price treats them all alike. Bidding lets buyers pay more for the calls they want most and lets publishers earn more from each one.

It also helps when buyers have limits. A buyer who has reached a daily cap or is closed simply does not bid, and the call goes to someone who can take it.

The auction, step by step

1. A call comes in. The caller dials a tracking number tied to a campaign and a traffic source.
2. The rules run first. Before anyone is asked to bid, the platform checks blocked numbers, repeat callers, opening hours, daily caps and state rules. Buyers who cannot legally or practically take this caller are left out.
3. Buyers are pinged at the same time. Every eligible buyer receives a request with the details they need to price the call. They are asked in parallel, not one by one, so the caller is not kept waiting.
4. Bids come back. Each buyer answers with a price, or with no bid.
5. The highest bid above your minimum wins. You set a minimum price for the campaign. Bids below it are ignored.
6. The call connects. The winning buyer gets the call, and the price is recorded against that call for billing and payouts.

Three settings that matter

Minimum bid

Your floor. If no buyer reaches it, the call does not go to the auction winner at a price you would not accept. Set it from what the call is worth to you and what you pay your affiliates for it.

Bid window

How long the platform waits for bids. Short enough that the caller barely notices, long enough for buyers to answer. Late bids are ignored.

Fall-back

What happens if nobody bids, or the winner does not answer. A sensible fall-back sends the call to the next buyer in a waterfall instead of dropping it.

Bidding and waterfalls work together

A waterfall tries buyers in an order you choose: buyer A first, then B if A is busy, then C. It is simple and predictable, and it suits fixed agreements. Bidding suits calls whose value varies. Many publishers run bidding on some campaigns and a waterfall on others, or use a waterfall as the fall-back when an auction gets no bids. Insight Dial supports both, along with a pre-transfer check that asks a buyer whether they will take a caller before the transfer happens.

Keeping affiliates paid fairly

When prices change from call to call, payouts need care. If an affiliate is paid a share of the payout, their earnings rise and fall with the winning bid. If they are paid a fixed rate per qualified call, the publisher carries the difference. Whichever model you use, every party should see the same record of each call: who sent it, who won it, what it sold for and what each person earned. That shared record is what prevents month-end disputes. How Insight Dial works shows the publisher, affiliate and buyer views side by side.

When real-time bidding is not the right choice

If you have one buyer, or a contract that fixes the price and the order, an auction adds little. Bidding pays off when you have several buyers who value callers differently and are willing to compete.
