# SPO.expert

> SPO.expert is an agentic AdTech platform — an AI agent that analyzes, validates, and optimizes programmatic supply paths, turning raw impression data into clear, actionable insights. Deterministic IAB rules decide what's verified; AI explains why — and what to do next.

SPO.expert shows where programmatic supply paths leak money, transparency and control — and proves it at impression level. Every impression is run through a fixed set of checks written from the IAB specifications (the OpenRTB SupplyChain object, sellers.json, ads.txt and app-ads.txt). Only then does AI put the result into words.

## Who It Is For

Platforms that sit inside the programmatic supply chain and receive inventory from partners: SSPs, ad exchanges, ad networks and DSPs — and the AdTech, supply and programmatic teams that run them.

## The Problem It Solves

Every impression that reaches a platform travels through a chain of sellers it didn't choose. Each hop is a fee, a claim and a risk — and most of that chain is declared, not proven. Typical leaks SPO.expert makes visible:

- Chains that break before they reach you — the declared chain never names your node, or the party that actually delivered isn't the last seller in it
- Sources that reach you only through middlemen — inventory one of your own senders could deliver straight, arriving through two or three intermediaries instead
- Publishers that list you as RESELLER — or not at all — in ads.txt / app-ads.txt, or under the wrong seller id
- Traffic with no supply chain object at all — impossible to verify, impossible to defend to a buyer

None of this shows up in a revenue report; all of it shows up in SPO.expert — with the paths, the senders and the dollars behind each line.

## How It Works

- Impression-level data is collected via a 1×1 tag carrying the schain (supply chain object)
- Validation: 15 deterministic checks confirm the schain object is present, complete and conformant to the IAB OpenRTB SupplyChain specification
- Verification: 40 deterministic checks confirm every hop against sellers.json, the publisher's ads.txt / app-ads.txt, the chain of authority, and the party that actually delivered
- Every impression is classified — verified / not verified / not validated / not analyzed — per sender, for every period (daily, weekly, monthly)
- AI explains the results and answers questions; it never decides a verdict and cannot state a number that isn't in the data

## What Users Get

- An interactive map of every supply path: source → every hop → the client → advertisers, classified and filterable by source, seller, sender, publisher and advertiser
- Three reports that end in an action, on screen and as CSV:
  - Errors — everything that blocks verification, organized by who can fix it (the client, the sender or the publisher), with the exact entry or line to add
  - Optimization — every path of the top sources ranked shortest to longest, one suggestion per path, and which senders could deliver straight what now arrives through middlemen
  - New Connections — partners the client pays through indirectly, ranked by the revenue routed through them, plus publishers where the client is RESELLER-only or missing
- An AI analyst that answers from the client's own data (never from benchmarks), states the scope of every answer, explains any error code, quotes the IAB specifications by page, finds alternative paths through current or former senders, and breaks down revenue, impressions, CPM and verified rate by source, sender, publisher or advertiser — including what drove a change

## Why It Matters

What you can't see, you can't negotiate, fix — or defend. Visibility is control: knowing, day by day, week by week, month by month, which of your paths you can prove.
