Stop paying for clicks that will never convert.

Warehouse-native traffic verification: score every paid visit for invalid traffic with a decision model, calibrated on your own conversions. You pay for compute instead of an enterprise contract.

The problem

Part of your ad budget pays for bots.

A share of paid clicks comes from bots, click farms and invalid placements. Ad platforms refund little of it, and the vendors that detect it charge enterprise contracts for a black box.

Replaces Lunio and CHEQ.

What you get
  • Every paid visit scored for bot and invalid traffic
  • Calibrated on your own conversions instead of a vendor's average
  • Exclusions and reports by campaign, placement and source
  • Runs in your warehouse at the cost of compute

How it works

  1. 01

    Collect signals

    A small probe collects server, client and behaviour signals first-party.

  2. 02

    Score and calibrate

    A decision model scores each paid session; outcomes calibrate it.

  3. 03

    Act on it

    Exclusions and reports by campaign and placement.

Have us build it

Enterprise, with our engineers

Our engineers add the traffic probe to your site, calibrate the decision model on your own conversion data, and send exclusions back to your ad platforms.

Build it yourself

Self-serve, after launch

Install Traffic Guard and the SegmentStream SDK. Paid sessions are scored daily and reported by campaign.

Install from the marketplace

Everything below installs into your workspace as code. Use it as it is, or change anything.

Questions

How is invalid traffic detected?

Server, client and behavioural signals from your own traffic are judged by a decision model, then calibrated against which visits actually converted.

How does the cost compare?

Ad-fraud vendors typically charge enterprise contracts. On SegmentStream Cloud, you pay for the compute and storage the models use.
