Closing FAST’s Measurement Gap: How Publishers Build Channel-Level Yield Intelligence

FAST is booming but measurement lags. Here’s how publishers build channel-level yield intelligence that unifies SSAI logs, identity and quality signals to win.

Closing FAST’s Measurement Gap: How Publishers Build Channel-Level Yield Intelligence

Closing FAST’s Measurement Gap: How Publishers Build Channel-Level Yield Intelligence

Free ad-supported streaming TV has crossed the chasm. Audience time is shifting into FAST channels, distribution partners are proliferating, and ad demand is flowing in. Yet the core measurement primitives required to run FAST like a business - reach, frequency, ad load, fill, error rate, true yield - remain inconsistent, siloed, or delayed. Publishers and channel operators feel the pain in revenue forecasting, packaging, and negotiations. This article maps a practical path to close the measurement gap by building channel-level yield intelligence. The goal is not a universal panel or a walled garden dashboard. The goal is a publisher-controlled system of record that fuses log-level delivery data, identity signals, quality telemetry, and revenue into one coherent model per channel, per platform, per day. We will cover the business case, the required data model, a reference architecture, and pragmatic analytics recipes that any publisher can implement with today’s tools. Where relevant, we cite standards and best practices from IAB Tech Lab and industry bodies to keep the approach aligned with where the market is heading.

Why FAST’s Measurement Gap Exists

FAST brings together live-linear publishing, on-demand libraries, server-side ad insertion, and a wide variety of OEM distribution environments. That heterogeneity creates predictable measurement challenges.

  • Inconsistent impression semantics: An “impression” can mean ad-stitched in SSAI, ad-start quartile, or verification-fired. Without common semantics, eCPM and fill are apples-to-oranges across partners.
  • SSAI opacity: Server-side stitching obscures device beacons and client-side verification. Ads are rendered as part of the stream, so client SDKs do not always observe starts, completes, or errors. IAB Tech Lab has pushed verification guidance for CTV and OM for CTV, but adoption and capabilities vary by device class and OEM partner.
  • Identity fragmentation: Device IDs differ by platform and policy, some are rotating or scoped, and co-viewing complicates person-level measurement. Household or account-level identifiers are often not available to the publisher on OEM-owned platforms.
  • Break-level data gaps: Many reporting interfaces aggregate at day or show level, omitting pod position, creative-level error codes, or splice failure reasons. That makes ad load tuning guesswork.
  • Walled garden asymmetry: OEM or platform dashboards may show reach and revenue, but rarely expose log-level event data sufficient for deduplication, multi-SSP attribution, or true supply-path analysis.
  • Verification and standards adoption: VAST 4.x features, Open Measurement for CTV, and authenticated signaling are uneven across the ecosystem, which limits standard QA and viewability practices in FAST environments.

These gaps are resolvable when publishers reframe the problem: rather than chasing an abstract perfect metric, build channel-level yield intelligence that is consistent, explainable, and actionable in your business context.

Define the Target: Channel-Level Yield Intelligence

Channel-level yield intelligence is an integrated model that answers five operational questions every day for every channel:

  • What did we deliver? Viewer hours, ad breaks, ad starts, ad completes, and content mix by platform.
  • How efficiently did ads monetize? Fill, eCPM by supply path, ad load minutes per viewer hour, and revenue per thousand viewer hours.
  • Where did quality degrade? Error rates by SSP, pod, creative, device class, and any QoE signals that correlate with drop-off.
  • Who is supplying demand? SSP and reseller paths mapped via sellers.json and the SupplyChain object to quantify take rates and path performance.
  • What should we change tomorrow? Tuning levers: ad load targets by daypart, supply path prioritization, floor adjustments, and content packaging for direct deals.

Getting there requires a clear data contract and some careful engineering. The good news: the building blocks exist in your SSAI logs, ad server logs, platform statements, and partner APIs. The hard part is harmonization and identity.

Measurement Ground Rules You Can Enforce

Before diving into architecture, set conventions that all partners must meet. Write them into insertion orders, SSP onboarding docs, and QA checklists.

  • Ad event taxonomy: Standardize on VAST quartiles and error codes. Treat “impression” as ad-start, not creative stitched, unless otherwise noted. Require error code mappings per partner. See IAB Tech Lab VAST 4.x guidance.
  • Timekeeping discipline: All logs must be in UTC, with both event_time and log_time, ISO-8601, and include a server processing latency field when possible.
  • Content metadata: Require program_id, series_id, episode_id, genre, rating, and channel_id at the ad request and fill. In FAST, channel_id is mandatory to attribute revenue and tune ad load by channel.
  • Supply-path transparency: Enforce sellers.json and the SupplyChain object on programmatic demand to identify intermediaries and resellers. This is critical for path performance and take-rate analysis.
  • Identity fields: Capture a scoped device identifier when permitted by platform policy, plus IP as a last-resort transient joining key for sessionization. Never persist raw IP beyond session stitching windows. Apply privacy-by-design.

The Data Model: Dimensions and Measures That Matter

A shared schema keeps analysis consistent even when sources differ. Below is a reference star schema for channel-level yield.

Core Dimensions

  • dim_channel: channel_id, channel_name, channel_owner, genre, language, rating, launch_date.
  • dim_platform: platform_id, platform_name, OEM, app_id, distribution_partner, region.
  • dim_device: device_class, device_os, model_family, screen_size_bucket.
  • dim_supply_path: ssp, reseller_chain, sellers_json_nodes, auction_type, deal_id, demand_channel.
  • dim_content: program_id, series_id, season, episode, content_type, duration_sec.
  • dim_time: date, hour, daypart, week, month, quarter.

Fact Tables

  • fact_stream: session_id, channel_id, platform_id, device_class, viewer_seconds, ad_breaks, join_time, leave_time, buffer_events.
  • fact_ad_event: ad_event_id, session_id, ad_request_id, ad_start, quartile, complete, error_code, pod_position, ad_duration, line_item_id, supply_path_id, gross_revenue, net_revenue.
  • fact_revenue_statement: period, platform_id, channel_id, currency, gross_revenue, fees, net_revenue, adjustments.

Derived Metrics

  • Viewer hours: sum(viewer_seconds) / 3600.
  • Ad load: sum(ad_duration) / viewer_hours.
  • Fill rate: filled_ad_slots / requested_ad_slots.
  • eCPM: 1000 * net_revenue / impressions.
  • RPMVH (revenue per thousand viewer hours): 1000 * net_revenue / viewer_hours.
  • Quality-adjusted yield: RPMVH * (1 - weighted_error_rate).

The key is RPMVH. In linear-like channels, viewer hours are the scarce resource. RPMVH normalizes revenue by attention time, enabling fair comparisons across channels, platforms, and time.

Reference Architecture: From Logs to Decisions

A modern data stack can support this without exotic infrastructure. The essential components are reliable ingestion, identity-aware sessionization, and metric computation with lineage.

  • Ingestion: Stream SSAI and ad server logs into cloud storage with schema-on-write. Pull SSP delivery and revenue via APIs daily. Land platform revenue statements monthly.
  • Normalization: Enforce the shared schema with dbt models or equivalent. Map partner fields to standard dimensions. Validate time zones, nulls, and categorical values.
  • Identity and sessionization: Use scoped device IDs where available. Build session windows with inactivity timeouts, typically 30-45 minutes for FAST. Deduplicate events by idempotency keys.
  • Attribution: Tie ad events to stream sessions and content using timestamps, ad break IDs, and channel IDs. Reconcile net revenue to statement totals each period.
  • Computation layer: Materialize daily channel-level aggregates and rolling 7 and 28-day windows. Store both pre- and post-reconciliation revenue versions for audit.
  • Observability: Track data freshness, completeness by partner, and error code rates. Alert on anomalies in fill, ad load, and RPMVH.

SQL Blueprint: Compute Channel-Level RPMVH and Fill

Below is a sample SQL pattern using a cloud data warehouse. It assumes normalized fact tables and demonstrates sessionization joins, fill, and RPMVH.

-- 1) Daily channel aggregates
with stream as (
select
date_trunc('day', join_time) as dt,
channel_id,
platform_id,
sum(viewer_seconds) / 3600.0 as viewer_hours,
count(*) as sessions
from fact_stream
where join_time >= dateadd('day', -35, current_date)
group by 1,2,3
),
ad as (
select
date_trunc('day', ad_start) as dt,
channel_id,
platform_id,
count_if(event_type = 'ad_start') as ad_starts,
count_if(event_type = 'ad_request') as ad_requests,
sum(case when event_type = 'ad_start' then ad_duration else 0 end) / 60.0 as ad_minutes,
sum(case when event_type = 'ad_start' then net_revenue else 0 end) as net_revenue
from fact_ad_event
where ad_start >= dateadd('day', -35, current_date)
group by 1,2,3
),
joined as (
select
s.dt,
s.channel_id,
s.platform_id,
s.viewer_hours,
s.sessions,
coalesce(a.ad_starts, 0) as ad_starts,
coalesce(a.ad_requests, 0) as ad_requests,
coalesce(a.ad_minutes, 0) as ad_minutes,
coalesce(a.net_revenue, 0) as net_revenue
from stream s
left join ad a
on s.dt = a.dt and s.channel_id = a.channel_id and s.platform_id = a.platform_id
),
metrics as (
select
dt,
channel_id,
platform_id,
viewer_hours,
sessions,
ad_starts,
ad_requests,
ad_minutes,
net_revenue,
case when ad_requests > 0 then ad_starts::float / ad_requests else null end as fill_rate,
case when ad_starts > 0 then 1000.0 * net_revenue / ad_starts else null end as ecpm,
case when viewer_hours > 0 then 1000.0 * net_revenue / viewer_hours else null end as rpmvh,
case when viewer_hours > 0 then ad_minutes / viewer_hours else null end as ad_load_min_per_vh
from joined
)
select * from metrics;

This pattern can be extended to include error rates, pod positions, and supply-path slices, for example:

-- Supply-path slice for a single channel
select
dt,
channel_id,
platform_id,
supply_path_id,
count_if(event_type = 'ad_start') as ad_starts,
sum(net_revenue) as net_revenue,
1000.0 * sum(net_revenue) / nullif(count_if(event_type = 'ad_start'), 0) as ecpm
from fact_ad_event
where channel_id = 'ch_123' and dt >= dateadd('day', -14, current_date)
group by 1,2,3,4
order by dt, ecpm desc;

Python Blueprint: Bayesian Smoothing for Low-Volume Channels

Low-volume channels exhibit volatile daily eCPM and fill. A simple Bayesian approach stabilizes estimates for planning and A/B decisions.

import pandas as pd
import numpy as np
# df: daily metrics per channel with columns ['channel_id','date','ad_starts','ad_requests','net_revenue']
# Prior from network-level averages
prior_fill_alpha = 50
prior_fill_beta = 50   # prior mean = 0.5
prior_ecpm_alpha = 2
prior_ecpm_beta = 0.2  # prior mean = alpha/beta = 10.0 currency CPM
def smooth_fill(ad_starts, ad_requests):
alpha_post = prior_fill_alpha + ad_starts
beta_post = prior_fill_beta + max(ad_requests - ad_starts, 0)
return alpha_post / (alpha_post + beta_post)
def smooth_ecpm(net_revenue, ad_starts):
# Gamma-Poisson approximation for CPM; use dollars per impression then scale
impressions = max(ad_starts, 1)
alpha_post = prior_ecpm_alpha + net_revenue
beta_post = prior_ecpm_beta + impressions / 1000.0
return (alpha_post / beta_post)  # smoothed CPM
df['fill_smoothed'] = df.apply(lambda r: smooth_fill(r.ad_starts, r.ad_requests), axis=1)
df['ecpm_smoothed'] = df.apply(lambda r: smooth_ecpm(r.net_revenue, r.ad_starts), axis=1)

This produces stable channel-level KPIs for decisioning while remaining responsive to real changes.

Identity and Sessionization in FAST

Identity is not one-size-fits-all in CTV and FAST, so focus on consistent sessionization.

  • Session keys: Compose session_id from channel_id, platform_id, device_id (scoped where allowed), and a rolling timeout. Persist only hashed or tokenized device identifiers with short TTLs in compliance with privacy policies.
  • Join windows: Ad events and stream events may arrive out of order. Use event_time based joins with a ±5 minute tolerance and idempotency keys to prevent duplicates.
  • Household dedup: If household-level IDs are present on certain platforms, use them for reach and frequency. If not, avoid over-claiming precision. Report both device-level and household-level metrics where supported.
  • Co-viewing: If you cannot infer co-viewing, don’t guess. Treat viewer hours as device-hours and document assumptions clearly in internal dashboards.

Quality Telemetry You Can Actually Use

SSAI hides much of the client surface, but you still have usable signals.

  • Ad error codes: VAST error 100-600 mappings indicate media file issues, timeout, or no ad. Trend by partner and pod position.
  • Break splice failures: SSAI servers can emit splice_error reasons. These correlate with rapid session abandonment. Flag partners where splice reliability lagging pulls down RPMVH.
  • Quartile drop-offs: Even without viewability, quartile completion rates are powerful proxies for user tolerance and creative fit by channel and daypart.
  • Buffer and join latency: From stream logs, combine rebuffer_count and join_time-to-first-frame to pinpoint where higher ad load harms QoE.

Quality-adjusted yield is simple: discount RPMVH by the weighted error and abandonment rates to avoid rewarding brittle revenue.

Supply-Path Intelligence for FAST

Programmatic demand is routed through SSPs and resellers. Without supply-path visibility, you cannot diagnose take rates or route demand to the most efficient paths.

  • Use sellers.json and SupplyChain: Map intermediaries from the bidstream and reconcile with partner-declared sellers.json entries. This reveals reseller trees and potential hops to bypass.
  • Track path eCPM and net take: Compare gross to net by path. Some resellers deliver unique demand. Others double-tax without lift. Route floors and preferential access accordingly.
  • Enforce directness: When possible, require direct relationships for preferred deals on high-performing channels. Keep resellers as backfill with lower floors.

Reconciling to Money: Statements and Trust

Always reconcile to cash. Platform and SSP statements are the ground truth for net revenue.

  • Monthly reconciliation: Sum log-level net_revenue and compare to statements per channel and platform. Record variance and investigate systematic skews by partner.
  • Attribution policies: When statements are only platform-level, allocate to channels based on ad minutes and eCPM weights. Keep a transparent lineage of allocations.
  • Currency and fees: Normalize currency at the event time FX rate or use period-average rates. Explicitly record platform fees, SSP fees, and ops adjustments.

Operational Playbooks: What to Do With the Intelligence

With consistent measures, publishers can run pragmatic plays that lift yield quickly.

  • Ad load tuning by daypart: Identify the ad load minute per viewer hour that maximizes quality-adjusted RPMVH per channel. Many channels exhibit diminishing returns above specific thresholds.
  • Supply-path reprioritization: Route more requests to the paths with superior net eCPM and lower error rates for a given channel and device class.
  • Floor and price experiment design: Use holdouts at the channel-platform level to test discrete floor steps. Read outcomes in RPMVH rather than eCPM alone.
  • Creative policy enforcement: Blacklist creatives that disproportionately drive quartile drop-offs on family or news channels. Protect channel brand equity while improving yield.
  • Packaged direct deals: Bundle top-performing channels and dayparts for direct-sold packages. Use your internal measurement as the basis for guarantees and makegoods.

Example: Daypart Ad Load Response Curve

A compact way to visualize the tradeoff between ad load and RPMVH is a response curve. Below is a sample query to generate curve points.

with agg as (
select
channel_id,
platform_id,
date_trunc('hour', ad_start) as hour,
sum(ad_duration)/60.0 / nullif(sum(viewer_seconds)/3600.0, 0) as ad_load_min_per_vh,
1000.0 * sum(net_revenue) / nullif(sum(viewer_seconds)/3600.0, 0) as rpmvh
from fact_ad_event a
join fact_stream s
on a.session_id = s.session_id
where a.ad_start >= dateadd('day', -28, current_date)
group by 1,2,3
)
select
channel_id,
platform_id,
width_bucket(ad_load_min_per_vh, 3.0, 18.0, 12) as ad_load_bucket,
avg(rpmvh) as avg_rpmvh
from agg
group by 1,2,3
order by channel_id, platform_id, ad_load_bucket;

This informs a control strategy: set channel-specific ad load targets by daypart to maximize quality-adjusted RPMVH.

Privacy and Compliance by Design

Measurement must earn trust. Design choices should minimize risk and align with regulatory guidance.

  • Data minimization: Store only fields necessary for sessionization and yield metrics. Hash device identifiers, enforce TTLs, and avoid persisting IP after session joins.
  • Purpose limitation: Use measurement data for analytics and operations only. Do not repurpose for cross-site tracking or audience building without a lawful basis and clear disclosures.
  • Access control: Segregate PII-free analytics from raw logs. Apply least-privilege access and audit trails.
  • Regional controls: Respect regional platform policies and regulatory requirements like GDPR and CPRA. Document vendor roles and DPAs with SSPs and OEMs.

Where Standards Help Today

Even without perfect adoption, certain standards improve FAST measurement quality.

  • VAST 4.x and verification: Modern error codes, mezzanine creatives, and verification signaling bring clarity to ad event semantics in CTV. See IAB Tech Lab’s VAST 4 guidance.
  • Open Measurement for CTV: OM for CTV is evolving to better support SSAI and device constraints. Where supported, it increases comparability of measurement across environments.
  • sellers.json and SupplyChain: These IAB standards formalize transparency of intermediaries and help quantify supply-path efficiency and take rates.
  • OpenRTB 2.6 for CTV: Additional fields for pod bidding and ad slotting help carry break context, improving pod-level analytics and pacing decisions.

    Red Volcano’s Perspective: Building on Supply-Side Intelligence

    Red Volcano operates on the supply-side intelligence layer across web, app, and CTV. For FAST publishers and channel operators, three capabilities compress time-to-value.

    • Channel and app discovery: Map the FAST landscape across OEM platforms, identifying channel portfolios, genres, and distribution footprints to inform where yield work will have the highest impact.
    • Technology and pathway telemetry: Track ads.txt, app-ads.txt, sellers.json, and SSP footprints of each channel to expose supply paths and reseller chains. Use this to prioritize direct paths and clean up duplication.
    • Benchmarking and alerting: Compare your channel-level yield patterns to category baselines. Flag anomalous shifts in fill, ad load, and RPMVH by platform, suggesting operational interventions early.

    Because Red Volcano focuses on SSP and publisher intelligence, our CTV data platform complements your internal logs with market context: who is selling your channels, how supply paths evolve, and where competitive channels are gaining share.

    A Phased Roadmap To Close the Gap

    You do not need to build everything at once. A staged approach stabilizes the foundation and compounds gains.

    Phase 1 - Data Contracts and Baseline Metrics

    • Standardize schemas with partners and implement daily aggregates for viewer hours, ad starts, fill, eCPM, and RPMVH per channel-platform.
    • Reconcile to statements monthly and document variance. Establish data freshness SLAs with partners.
    • Ship a single dashboard that every team uses, with definitions written into the UI. Kill duplicative spreadsheets.

    Phase 2 - Identity, Sessionization, and Quality

    • Implement sessionization with scoped IDs and timeouts. Add quartile-based completion analytics and VAST error taxonomy.
    • Introduce quality-adjusted yield to balance RPMVH with stability and user experience.
    • Start supply-path analysis using sellers.json and SupplyChain. Identify top 3 paths per channel for prioritization.

    Phase 3 - Optimization and Automation

    • Ad load control loops by channel and daypart, using response curves and safe bounds.
    • Floor testing framework with holdouts, measuring RPMVH deltas and error impacts.
    • Deal packaging with channels and dayparts that deliver repeatable quality-adjusted yield.

    Phase 4 - Advanced Signals and Partnerships

    • Integrate OEM-specific telemetry where available to enrich QoE models.
    • Ad verification and OM for CTV pilots on supported devices to layer comparable measurement.
    • Collaborate on standards with SSPs and partners to adopt OpenRTB 2.6 pods and authenticated signaling.

    Common Pitfalls and How to Avoid Them

    • Chasing perfect identity: Device or household dedup across all platforms is not required to optimize channel yield. Prioritize session fidelity and consistent RPMVH first.
    • Over-indexing on eCPM: eCPM is necessary but not sufficient. A high eCPM with low fill or high errors can reduce RPMVH. Optimize the portfolio on revenue per unit of attention.
    • Ignoring statements: Log-level revenue must reconcile to cash. Building on un-reconciled numbers erodes trust and misguides negotiations.
    • One-size ad load: Channels differ. A kids channel will have different tolerance than a crime drama channel. Tune per channel and daypart.
    • Opaque partner relationships: Without sellers.json and SupplyChain mapping, you will miss hidden fees and duplicate resellers.

    Negotiation Leverage: Using Intelligence in the Market

    Channel-level yield intelligence is not just for ops dashboards. It powers smarter partner conversations.

    • With SSPs: Share channel-specific error codes, pod positions, and response curves to justify floors and preferential demand routing. Ask for log-level transparency and sellers.json hygiene.
    • With OEM platforms: Use reconciled RPMVH and quality metrics to negotiate placement, featured rows, or promo slots that lift viewer hours and ad breaks predictably.
    • With advertisers: Package the highest quality-adjusted RPMVH dayparts with genre fit and quartile completion proof. Commit to stable ad load targets and makegoods based on your measurement.

    Example KPI Scorecard For A Single Channel

    A monthly channel scorecard should fit on one page and update daily.

    • Viewer hours vs plan and YoY.
    • Ad load minutes per viewer hour vs target.
    • Fill rate and eCPM trend with 7-day smoothing.
    • RPMVH and quality-adjusted RPMVH.
    • Top supply paths by net revenue contribution and error rates.
    • Top error codes and quartile completion deltas.

    With this, executives get a clear readout and operators have specific levers to pull.

    Implementation Cheatsheet: Data Contracts

    Embed requirements in partner contracts and test plans.

    
    Field requirements:
  • event_time: ISO-8601 UTC
  • channel_id: publisher-defined, stable
  • platform_id: OEM + app_id
  • program_id / content_id: stable, optional for channel-only schedules
  • session_id: partner if available, else publisher sessionization id
  • ad_request_id: unique per request
  • event_type: ad_request | ad_start | quartile_25 | quartile_50 | quartile_75 | complete | error
  • error_code: VAST error taxonomy
  • ad_duration: seconds
  • supply_path: ssp;reseller1;reseller2
  • currency: ISO code
  • net_revenue: post-fee revenue in currency
    
    QA checklist:
    <ul>
    <li><strong>Time drift</strong>: |event_time - log_time| under 5 seconds median, 60 seconds p95.</li>
    <li><strong>Uniqueness</strong>: ad_request_id unique per day across feed.</li>
    <li><strong>Completeness</strong>: 99 percent of ad_start events have channel_id and platform_id.</li>
    <li><strong>Error mapping</strong>: 95 percent of error events have populated error_code.</li>
    </ul>
    ## When Log-Level Is Not Available
    Sometimes you only get platform dashboards and monthly statements. You can still build useful intelligence.
    <ul>
    <li><strong>Top-down allocation</strong>: Use ad minutes schedule by channel multiplied by platform average eCPM to allocate statement revenue to channels, then calibrate with any spot log samples.</li>
    <li><strong>Panel augmentation</strong>: Complement with third-party streaming panels to validate reach trends. Use cautiously for RPMVH inference.</li>
    <li><strong>Experiment cadence</strong>: Run platform-level ad load experiments for two-week windows and read revenue deltas against viewer hours.</li>
    </ul>
    Document assumptions and quantify uncertainty bands in dashboards. Stakeholders appreciate transparency more than false precision.
    ## The Road Ahead: What Will Improve Measurement
    Industry initiatives and product maturation are closing gaps.
    <ul>
    <li><strong>Better pod signaling</strong>: OpenRTB 2.6 pod objects help buyers and sellers optimize pod composition, improving break-level analytics.</li>
    <li><strong>OM for CTV adoption</strong>: As more devices support OM in CTV contexts, verification will move up the maturity curve and standardize ad event semantics.</li>
    <li><strong>Authenticated signaling</strong>: Authenticated connections reduce spoofing and improve supply-path trust. Combined with sellers.json hygiene, this will clean up duplicative paths.</li>
    <li><strong>OEM telemetry partnerships</strong>: Select OEMs are exposing more QoE telemetry to publishers under privacy constraints, enabling better quality-adjusted yield models.</li>
    </ul>
    ## Conclusion: Make Channels Operate Like P&Ls
    FAST’s measurement gap is solvable with a publisher-first approach. Treat each channel like its own P&L with standardized inputs, reconciled revenue, and actionable levers tied to RPMVH. Perfection on identity or verification is not a prerequisite to lift yield. Consistency, transparency, and disciplined experimentation are.
    Publishers who build channel-level yield intelligence will negotiate better, allocate inventory smarter, and protect user experience while growing revenue. The competitive advantage is not a secret algorithm. It is the organizational muscle to define metrics, reconcile to money, and make daily decisions on the back of trustworthy data.
    Red Volcano’s supply-side intelligence - from channel discovery to sellers.json telemetry - accelerates this journey. Combined with your internal logs and business context, you can close the measurement gap and operate FAST with confidence.
