MFA Feed is a continuously updated inventory of Made-for-Advertising domains, scored daily across 30+ signals. It helps buyers, SSPs, exchanges, and verification teams spot low-quality inventory earlier and act on it with confidence.
Made-for-Advertising sites are built primarily to monetise programmatic demand rather than create meaningful audience value. They often combine thin or repetitive content, aggressive ad load, suspicious infrastructure patterns, and monetisation signals associated with arbitrage.
The problem is not recognising that MFA exists. The problem is identifying it consistently, at scale, and with enough evidence to do something useful with it.
Red Volcano’s MFA Feed closes that gap.
Media buyers, agencies, DSPs, and verification teams need a practical way to reduce wasted spend and improve supply quality.
MFA Feed helps you identify domains that show strong MFA characteristics, refresh exclusion lists, support pre-auction controls, and strengthen reporting around where budget is actually going. When low-quality inventory slips into the plan, performance becomes harder to defend and quality media loses out.
SSPs, exchanges, and publishers need a cleaner view of what is moving through the supply path.
MFA Feed helps teams investigate suspicious properties, monitor ads.txt relationships, support onboarding decisions, and show buyers a more credible supply story. When MFA inventory sits too close to premium supply, it drags down trust in the marketplace around it.
MFA Feed is designed to be inspectable. You can see the classification, the supporting signals, and the outcome.
We ingest domains daily from multiple sources, including zone files, ads.txt relationships, referral patterns, and page-level capture. That gives us a broad and regularly refreshed view of the market.

Each domain is scored across 30+ signals covering monetisation density, content quality, infrastructure patterns, and other indicators associated with MFA behaviour. The result is a score from 0 to 100, plus a red, amber, or yellow tier.
signals 30+ (ads, content, infra) scale 0–100 output tier = red | amber | yellow
Domains are published to the feed with the signals that informed their classification. Data is available through the dashboard, API, and exports. If there is a query, users can flag it for review.
outputs dashboard · API · CSV / JSON flag → review user-initiated · human-reviewed cadence daily
Every result includes the signals behind the score, so teams can inspect, review, and make policy decisions with context.
High confidence of MFA indicators
These domains show strong evidence across multiple signals — excessive ads.txt entries, high reseller density, thin or templated content, and monetisation patterns typical of MFA-style sites. In most workflows, these are candidates for immediate exclusion or escalation.
Meaningful risk signals
These domains show several characteristics commonly associated with MFA, but may require review before a final decision. They are often the right focus area for buyer review queues, supply audits, or onboarding checks.
Monitor closely
These domains have triggered one or more relevant signals but may still sit in a grey area. They belong on a watch list rather than in a final verdict bucket.
MFA Feed is available through a documented REST API, with CSV and JSON exports for teams that need to automate nightly jobs, supply reviews, or internal reporting. Use it to power blocklist refreshes, supply-path analysis, onboarding checks, and internal dashboards without rebuilding your own classification layer from scratch.

Buy-side teams use MFA Feed as a reference dataset for exclusion lists, pre-auction filtering, and internal visibility into where budget is ending up.
MFA Feed supports your supply-quality checks, onboarding context, and a clearer view of the MFA footprint moving through the market.
Whether you are trying to cut wasted spend, clean up supply, or give clients a more defensible quality story, MFA Feed is designed to plug into the workflows where those decisions already happen.
MFA Feed is currently free while we refine the scoring model with real-world usage and feedback. Beta access includes the full feed across all tiers, API access, exports, team-level access, and a review process for contested classifications.
If you want to reduce MFA exposure, strengthen exclusions, or tell a cleaner supply story, MFA Feed gives you a practical place to start.
