FAQs
Answers to common questions about The Publisher Coalition, its priorities, and how organizations can get involved.
What is the Publisher Coalition?
The Publisher Coalition is a publisher-led industry initiative founded by industry leaders to give publishers and the wider supply side a voice in how mobile advertising standards are created, enforced and evolved.
Why was the Publisher Coalition created?
Publishers have often been expected to comply with standards and verification frameworks they had little role in creating. The coalition exists to support publisher representation, clearer oversight and practical routes for industry engagement.
What does the Publisher Coalition aim to achieve?
The coalition focuses on independent IVT monitoring, stronger ad-quality standards, verification transparency, publisher representation, collective action and IAB engagement.
What is independent IVT monitoring?
Independent IVT monitoring means oversight of invalid traffic and ad-quality verification by a body free from commercial bias, with clearer evidence and a fair process when inventory is flagged.
How will the coalition improve ad quality?
The coalition supports ad-quality standards that protect the user experience, reduce churn and improve trust between publishers, advertisers, developers and users.
Why is verification transparency important?
Publishers should understand how their inventory is monitored and have access to the data behind enforcement decisions. Transparency gives publishers a clearer basis for resolving incorrect or disputed findings.
Why is the coalition needed now?
Mobile advertising technology is evolving faster than many of the frameworks that govern it. Without publisher input, structural issues around verification, accountability and enforcement risk becoming more embedded.
How did the initiative begin?
The concept was presented by Charlie Castell during his "Steps to Recovery" session at MAU Vegas 2026. The response from publishers and industry stakeholders highlighted demand for coordinated publisher advocacy.
Who can join the Publisher Coalition?
The coalition welcomes publishers of all sizes, SSPs, DSPs, IVT verification companies, independent adtech companies and industry bodies. It is also relevant to brands, agencies and mobile game developers that support more accountable standards.
Who is behind the Publisher Coalition?
The Publisher Coalition is led by Charlie Castell and was founded by industry leaders with direct experience of the challenges publishers face in mobile advertising.
How will the coalition work with the IAB?
The coalition intends to work with the IAB on industry initiatives, committee participation and routes for making publisher perspectives part of how mobile advertising rules are shaped.
