Why In-App, not MFA, is the Advertising Solution Made for Advertisers

Summary

The article frames MFA sites as a programmatic waste trap: low-utility pages built to harvest impressions, autoplay ads, and low-intent clicks while flattering viewability and CPM metrics. For ad ops teams, the risk is not just brand adjacency but false success—campaigns can hit view-based KPIs while producing little meaningful attention. The author cites ANA research: a 2023 study found MFAs represented 21% of audited 35 billion impressions, and a Q1 2026 ANA study cited MFA exposure at 1.1% while flagging AI-generated slop as an emerging subtype requiring mitigation.

The proposed antidote is in-app advertising. First, the app-download step creates useful friction that signals intent and makes users more likely to engage with app content and ads; MFA pages have no such utility. Second, in-app formats show stronger quality signals: DoubleVerify’s 2022 report found 72.5% display and 77.4% video viewability in-app versus 63.6% and 71.4% on mobile web, and mobile app brand unsuitability of 4.4% versus 9.7% for mobile web.

Third, in-app has guardrails such as Google’s ads.txt framework for approved publishers, and fraud risk can be reduced by buying only well-documented, popular apps rather than hundreds of unverified ones. Fourth, in-app creative can use interactivity to increase attention and retention. MFA’s worst feature is metric inflation: viewability and CPMs can rise even when users immediately leave and absorb no brand message.

Blocking individual MFA domains is whack-a-mole; changing the mix toward vetted in-app supply is more durable. The takeaway is to rethink the marketing mix: audit programmatic placements, avoid MFA-contaminated inventory, demand verified publisher/app sources, and shift a significant budget share to in-app. Ad ops should pair viewability with attention, brand-safety, and fraud metrics, then scale in-app where verified supply and intent align.

Analyst Note

The key implication here isn't the MFA definition — most ad ops teams already recognize a low-utility page on sight — but who's making the argument. This piece comes from an in-app network executive, and its conclusion maps neatly onto that vendor's inventory. That doesn't invalidate the viewability benchmarks cited, but it does mean the sourcing deserves a second look: the DoubleVerify figures date to 2022, and the ANA numbers quoted are hard to reconcile, with 2023's 21% share of audited impressions sitting alongside a Q1 2026 exposure figure near 1%. Different panels and methodologies, certainly, but worth watching how that gap gets explained as MFA reporting matures and AI-generated content enters the taxonomy.

The industry signal holds regardless of the messenger. MFA scrutiny has shifted from brand safety toward measurement integrity — the article's sharpest point is that viewability and CPM optimization can actively reward the placements that waste budget. For UA and monetization teams, that reframes in-app's download friction as a qualification signal rather than a cost, and it raises the bar on supply verification through app-ads.txt and publisher allowlists rather than inherited intermediary controls. Timing matters: AI tooling makes low-utility inventory cheaper to produce at scale, which pressures the controls that currently keep it out of premium environments.
