MarkApp Launches Shelf, AI Visibility Analytics That Measures a Brand’s Share of the AI Answer

by ExchangeWire PressBox on 13th Nov 2026 in News

MarkApp, the programmatic media infrastructure company behind Pantheon, Harion, and MarkDash, today (14th November, 2026) announces the launch of Shelf by MarkApp, an AI visibility analytics platform that measures how AI assistants recommend brands, products and stores, and turns the findings into a ranked plan to win more of those answers.

More buying journeys now begin with a question to an AI assistant: which brand should I choose? The answer names a short list, and the customer acts on it. For most brands, that moment is invisible: they cannot see whether they are named, in what order, on what evidence, or where the facts are wrong.

Shelf makes that moment measurable. Each month, a fixed panel of 50 to 100 real customer questions, covering a brand’s competitors, the topics that decide the purchase, and the places and languages of its customers, is put to each assistant through its official API, three times, with web search on. Every answer is read for who is named, in what order, why, and from which sources.

What brands receive

AI Visibility Score and share of the AI answer: a score from 0 to 100 and the brand’s share against every competitor, by assistant, topic, place and language.

Why AI picks a brand, or a rival: the reasons assistants give, quoted from their answers.

The sources AI trusts: the websites cited, with an outreach list of those worth winning.

Wrong facts, flagged: inaccurate or outdated descriptions, traced to their source answer.

AI SEO: a website score out of 100, with paste-ready FAQ, schema, llms.txt and robots.txt fixes.

A plan, not just a chart: ranked actions across content, sources and media, in a live dashboard.

From insight to media

Shelf is the insight layer of the MarkApp ecosystem. Where competitors win the answer, the audiences, places and topics become a media plan activated through Harion, MarkApp’s DSP, with audience, contextual, geo and language targeting across CTV, in-app and web. Brands buying through their own DSP or agency can reach the same premium supply through Pantheon, and MarkDash reports spend and delivery across the stack in one view.

"Your customers already ask AI which brand to choose, and the decision is often made inside the answer. Most brands still cannot see that moment, let alone manage it. Shelf gives marketing leaders a consistent measure of their share of the AI answer, explains why it falls the way it does, and connects every gap to an action: on their website, in their sources, or in media they can buy through our stack. It is built to end in a plan, not a chart." - Sotiris Oikonomou, founder and managing director, MarkApp
