Is "Underpriced Attention" Real, or Just a Good Story? Auditing the Day-Trading-Attention Thesis

Last reviewed 2026-07-20. Written by Chandranshu Kumar, Founder, Raveneye Global. · 9 min read

The phrase "underpriced attention" describes a real, well-documented phenomenon: ad dollars structurally lag attention as it migrates to new surfaces, a pattern with decades of evidence behind it. The specific claim that a named platform is currently underpriced, expressed as a precise CPM comparison against a rival platform, is a different and much weaker kind of statement. Popular framings of "underpriced attention" are trade-book packaging of real economics, not themselves a measurement, and most of the specific platform-pricing numbers circulating to support them trace back to unattributed marketing content rather than a disclosed, primary methodology. Both are true at once: the underlying pattern is real, and most of the specific numbers used to sell it are not verifiable.

Where the phrase comes from

The phrase "underpriced attention" was popularized by Gary Vaynerchuk in his 2024 book Day Trading Attention, which advises marketers to "figure out where underpriced attention is and learn how to effectively storytell in those places." Underpriced, in this framing, means a low cost relative to the actual attention a placement receives, not simply a low sticker CPM.

This is a trade book, not an empirical study. It is a practitioner's memorable packaging of a pattern, and it should be read and cited as exactly that: a thesis worth taking seriously, not a research finding to repeat as settled fact.

The part of the thesis that is well corroborated

The underlying claim, that attention migrates to new surfaces faster than ad dollars follow, is one of the best-documented patterns in media economics. Mary Meeker's 2013 KPCB Internet Trends report showed US consumers spending roughly 12 percent of their media time on mobile devices while mobile captured only about 3 percent of ad spend, a gap that later editions tracked narrowing toward equilibrium by around 2018.

The same pattern reappeared a decade later on a different surface. IAB's 2023 Internet Advertising Revenue Report found digital audio accounted for roughly 20 percent of adult US time spent with digital media but only about 3.1 percent of digital ad revenue, and podcast advertising, while growing 17.6 percent year over year to $2.862 billion in 2025, held essentially flat at 2.8 percent of total internet ad revenue, meaning the dollar share is not closing at anywhere near the rate the underlying attention share would predict.

What "underpriced" does not mean, even when the pattern is real

A documented aggregate gap between time-spent and ad-spend at the level of an entire medium, mobile in 2013, digital audio in 2023, is not the same claim as "platform X is underpriced relative to platform Y today, for your specific business." The aggregate gap describes a population-level pattern across an entire format. It does not, on its own, prove which specific platform is the better buy for a specific advertiser's specific audience right now.

This is where popular "day trading attention" content most often overreaches: it borrows the credibility of the aggregate, well-evidenced pattern to support a much narrower and much less evidenced claim about a specific current platform comparison.

The specific CPM claims: what we found when we looked for the primary source

Searches for a primary, methodologically disclosed comparison of specific platform CPMs, the kind of claim commonly used to argue a particular platform is "underpriced" right now, returned overwhelmingly SEO and agency blog content. One frequently circulated figure claims a specific platform averages roughly $3.50 CPM against roughly $6.59 for a rival platform, sourced to an unnamed "Global Ad Cost Index" with no disclosed methodology, sample size, date range, or geography.

That is not evidence. It is marketing content dressed as a statistic, and it should be treated as un-auditable rather than repeated. This article deliberately does not restate that or any similar specific CPM figure as fact, because no primary, disclosed source for it could be located.

Why vendor CPM claims are structurally unreliable as a category

Platform-comparison CPM claims circulating in marketing content typically fail on the same points every time: no disclosed sample size, no disclosed date range, no disclosed geography or vertical, and no disclosed methodology for how the average was computed. Average CPM also varies enormously by targeting, vertical, seasonality, and auction dynamics on any single platform, which means a single headline number was never going to represent what a specific advertiser would actually pay.

The macro-level record confirms that ad-dollar reallocation is happening, just unevenly. IAB and PwC's FY2025 Internet Advertising Revenue Report found total US internet ad revenue reaching $294.6 billion, up 13.9 percent year over year, with social media ad revenue growing fastest at $117.7 billion, up 32.6 percent, while podcast and audio's revenue share stayed flat despite rising time-spent, evidence that the market does correct toward attention-rich surfaces, but with format-specific lag rather than a clean, immediate repricing any single vendor CPM claim could reliably predict.

Glossary

Underpriced attention: A practitioner term, popularized by Gary Vaynerchuk, for a channel where the cost of a placement is low relative to the actual attention it receives; a directional framing, not a measurement methodology.
Attention-spend gap: The documented, recurring pattern where advertising-dollar allocation to a medium lags behind the share of attention that medium actually receives, observed across mobile (2013) and digital audio (2023).
Un-auditable claim: A statistic circulated without a disclosed methodology, sample size, date range, or source, making it impossible to verify independently; common in vendor and agency marketing content.

Straight answers

Frequently asked questions

Is "day trading attention" a legitimate marketing strategy?

The underlying pattern it describes, attention migrating to new surfaces faster than ad dollars follow, is well documented across multiple decades and multiple media formats. The specific book is a practitioner's framing of that pattern, useful for communicating the idea, but it is not itself a research study and should not be cited as if it produced new evidence.

Is TikTok actually cheaper than Meta right now?

We could not verify a primary, methodologically disclosed comparison for this. Every specific CPM figure we found tracing this claim originated in unattributed marketing content with no disclosed sample, date range or geography. This needs first-party measurement for your specific audience and vertical, not a borrowed headline number.

Why do vendor CPM comparisons keep circulating if they are not verifiable?

Because a specific, simple number is more shareable and more persuasive than "it depends on your audience, vertical, and targeting," even when that is the accurate answer. Average CPM on any platform varies by targeting, seasonality, vertical and auction dynamics, so a single cross-platform average was never going to be reliable for a specific advertiser's decision.

What should replace a vendor CPM claim when deciding where to advertise?

A first-party, domain-specific read of where your own audience's attention sits and what it actually costs to reach them, rather than a secondhand industry-average figure. This is the difference between a Visibility Corpus read of your actual market and repeating a number from a blog post.
