Only the 47-second threshold is public on Lumen's page; the other claims come from a Meta executive's LinkedIn summary.
In 60 seconds
- Lumen Research, Amazon Ads and Cint analysed 270 cross-media campaigns; the median cumulative attention needed for purchase intent was 47 seconds.
- A Meta planning director's summary says cumulative attention predicted brand lift about eight times better than raw exposure counts.
- The same summary says streaming TV followed by online ads gave 30% more brand lift than the reverse order.
- The white paper is gated, and markets, dates, media mix and measurement method are undisclosed.
Impact Layer
- What changed
- Attention is being tied to a number of seconds per outcome, not just a viewability or exposure count.
- Why it matters
- If attention thresholds hold, frequency and reach plans could be judged by cumulative seconds looked at, not impressions served.
- Who is affected
- Media planners, brand measurement teams and agencies buying on attention metrics.
- Martech stack area
- Analytics, Advertising
- Stack impact
- Ask vendors how attention is measured (observed, predicted or blended) and treat the 47-second figure as a median for one set of campaigns, not a target.
- Business impact
- Low PPC Land relays a LinkedIn summary by Meta's Peter Buckley; Lumen's public page has no date and the full paper is available only through Amazon representatives. All campaigns appear to include Amazon as a media partner.
- Related technologies
- What to watch
- A published methodology and replication on non-Amazon campaigns.
PPC Land reported on October 13, 2026 on a Lumen Research study of 270 cross-media campaigns, produced with Amazon Ads and Cint.
What is public
Lumen’s page states: “The study found a median of 47 seconds of Cumulative Attention is needed for purchase intent.” It is the only one of five brand metrics (recall, awareness, consideration, favourability, purchase intent) with a threshold published.
Extra claims from a LinkedIn summary
Peter Buckley, Connection Planning Director at Meta, posted a summary the same day. His claims, not on Lumen’s page:
- Cumulative attention predicted brand lift about eight times better than raw exposure counts.
- Streaming TV followed by online ads produced 30% more brand lift than the reverse order.
- About a quarter of the highest-attention campaigns showed no purchase intent lift.
Gaps
The markets, campaign dates and media mix; how attention was measured; the spread around the median; and whether creative quality, not attention, drives the results, a question raised by Rares Rusu of 40Folds. All campaigns appear to have used Amazon as a media partner.
Our read
A single median is a prompt to test, not a plan. Ask how any attention vendor defines and validates its numbers.
