The brief
What Teams Look For
Auctions on a plan that fits
Buyers bid on each call in real time, without moving up to a large plan first.
Ad data that reaches Google Ads
Qualified calls go back to Google Ads as conversions, so bidding learns which clicks turn into paying calls.
Spend you control
Usage is prepaid, so a busy day never turns into a surprise bill.
Qualification before the transfer
An IVR asks the questions buyers care about and passes the answers to routing and the auction.
