Know where your budget leaked.
Fix it before the next campaign.
Upload a DV360 or other DSP campaign report to see exactly which domains routed through resellers, what it cost you, and how to fix it. Or bring a URL list and we'll build the cleanest paths before you spend a dollar.
Every reseller hop takes 15–20% before reaching the publisher. Alargo scans your domains against the publishers and 2,500 SSPs, scores your supply paths, and exports a cleaner list to DV360, TTD, or Xandr in seconds.
Upload any allowlist • Get your Supply PathScore™ in under 60 seconds • No credit card required
We also identify cleaner, more direct supply paths where available.
Your supply path. Optimized.
The assistant scans your publisher against live data in real time, flagging unauthorized paths, reseller leakage, and bid inefficiency before your next campaign runs.
- ✓ Instantly verify any publisher list against live data
- ✓ Surface direct SSP alternatives that win more auctions
- ✓ Export optimized lists ready for your DSP
The Problem
Performance depends on the path, not just the bid.
Between your DSP and the publisher, there's a supply chain. Some routes are direct and authenticated. Others layer in intermediaries that add cost, latency, and noise. Most teams only see this after performance moves.
Hidden Friction
Longer, indirect routes slow bids and reduce access to premium inventory.
Opaque Supply
DSP reporting shows where you served — not the cleanest way you could have bought.
No Common Metric
Without a single grade, it's hard to compare lists, track changes, or align stakeholders.
The Solution
PathScore™ makes supply efficiency measurable
PathScore™ is the industry's first pre-bid score that shows how efficiently an ad dollar reaches a publisher. It grades your allowlist from 0–100 — so teams can act before performance slips.
PathScore™
A single grade you can compare
How to read it
PathScore™ reflects path structure and observed supply relationships, not media quality or brand safety.
Compare campaigns
Quickly see which allowlists are cleaner and which need attention.
Track improvement
Watch PathScore™ move over time. Q1 was 62, now it's 84.
Align stakeholders
A single grade makes conversations simpler across brands, agencies, and ops.
