Traffic is the easiest media signal to compare. Two outlets, one with 800,000 monthly visits and one with 400,000, look obviously different on a shortlist. The trouble is that traffic alone says nothing about whether those visits resulted in reading. A high-traffic outlet where readers leave after eight seconds delivers worse PR coverage than a lower-traffic outlet where readers stay for three minutes. The first outlet looks stronger on a media plan. The second produces measurably better outcomes. Reading Behaviour is the Outset Media Index (OMI) normalized 0-10 signal that fills the gap. It blends three component signals into one figure that surfaces why traffic alone is not enough for PR outlet selection. What Reading Behaviour Measures The question of what reading behaviour is in media analysis has a precise answer in OMI. Reading Behaviour is a normalized 0-10 score that captures how readers actually move through a publication, calculated from three component signals: Visit Duration Pages/Visit Bounce Rate. The score sits in OMI's public Audience Engagement panel and feeds into the GRP overall rating. Any one of the three component signals on its own can mislead. An outlet with long Visit Duration but high Bounce Rate often has time-on-page averages skewed by a small subset of readers. An outlet with high Pages/Visit but very short Visit Duration often has aggressive infinite-scroll mechanics that inflate the figure. The blended Reading Behaviour score corrects for the noise in each component and produces a number that reflects something the individual signals cannot: the depth of attention the average reader gives the publication. That figure is the closest available proxy for whether a PR placement will be read or scrolled past. The Three Component Signals The three signals each measure something different about reader behaviour, and the way they combine into Reading Behaviour reflects what each one tells outlet-side engagement analysis. Outlet-level engagement signals start here. Visit Duration Average time a reader spends on the page. Visit Duration tells whether readers stop long enough to absorb a story or scroll past it. Long duration suggests editorial content depth that holds attention. Short duration often signals headline-driven traffic with no follow-through. The signal matters most for outlets where the launch story needs to be fully read to make sense. Pages/Visit Average pages a reader views in one session. Pages/Visit measures whether readers explore further once they land on the outlet. High Pages/Visit indicates content discoverability and editorial structure that encourages reading past the original story. Low Pages/Visit suggests readers come for one piece and leave, which limits how much campaign coverage compounds within the same outlet. Bounce Rate Share of readers who open one page and leave without further interaction. Bounce Rate is the negative-signal counterweight to the other two. High Bounce Rate indicates readers arrive, glance, and exit, so the publication functions as a referral surface instead of a reading destination. Low Bounce Rate suggests readers commit to the page once they arrive, which makes the outlet better suited to deeper PR coverage. Anyone working through visit duration pages per visit bounce rate PR decisions reads all three signals together, not in isolation. Why Two Outlets With Identical Traffic Can Have Very Different Reading Behaviour Scores The shortlist illusion is the central reason why measuring outlet engagement sits apart from how much traffic the outlet receives. Consider two outlets with the same Average Traffic (3M) but divergent component signals: Signal Outlet A Outlet B Average Traffic (3M) 600,000 600,000 Visit Duration 0:42 2:18 Pages/Visit 1.3 2.7 Bounce Rate 78% 41% Reading Behaviour (0-10) 3.1 7.4 Outlet A has the same surface reach as Outlet B but delivers a fundamentally different placement outcome. A press release on Outlet A reaches roughly the same number of browsers, but only a fraction stay long enough to absorb the message. Outlet B's lower bounce and higher pages-per-visit mean readers commit. PR planning that treats both outlets as interchangeable misses the most important variable in placement quality. Reader engagement metrics for media outlets exist precisely to surface this gap. When to Prioritise Reading Behaviour Over Reach Reading Behaviour and Average Traffic carry different weights depending on the campaign goal. Three scenarios where Reading Behaviour outranks Average Traffic in outlet selection: a complex product launch where the message requires absorption (FinTech compliance details, Web3 protocol changes, technical SaaS releases); a reputation-building campaign where coverage needs to be read by analysts and decision-makers, not glanced at investor or partner reporting where the goal is not impressions but proof that the message landed with engaged readers. Three scenarios where Average Traffic still wins: mass-audience consumer announcements brand-awareness campaigns where breadth matters more than depth time-sensitive news where visibility velocity matters more than absorption These are engagement metrics for PR outlet selection in practice. Different campaigns weigh Reading Behaviour and Average Traffic differently, and the PR lead's job is to know which weighting matches the goal before building the shortlist. How Reading Behaviour Fits Into OMI's GRP Rating Reading Behaviour is one of the normalized component signals that feed into the GRP overall rating. The contribution is meaningful but not dominant. GRP also weights Unique Score, Composite Score, Average Traffic, LLM Referral Share, and others. The implication: an outlet with a strong Reading Behaviour score but weak performance across the other signals will have a moderate GRP, not a high one. The reading behaviour media outlet signal is more useful to read directly than to infer from GRP, and the PR lead checks both. FAQ What is Reading Behaviour in media analysis? Reading Behaviour is OMI's normalized 0-10 signal that captures how readers actually move through a publication. It blends Visit Duration, Pages/Visit, and Bounce Rate into one figure that surfaces the depth of attention the average reader gives the outlet. How is Reading Behaviour measured? Reading Behaviour combines three component signals from OMI's Audience Engagement panel: Visit Duration (average time on page), Pages/Visit (average pages per session), and Bounce Rate (share of single-page exits). The blended 0-10 score corrects for noise in each individual signal. Why does Reading Behaviour matter more than traffic for PR? Two outlets with identical Average Traffic can deliver completely different placement outcomes. Traffic measures who arrives. Reading Behaviour measures who stays long enough to read the placement. For PR campaigns where the message needs to be absorbed instead of glanced at, Reading Behaviour predicts outcomes more reliably than traffic. How does OMI use Reading Behaviour in outlet rating? Reading Behaviour is one of the normalized signals that feeds into the GRP overall rating, alongside Unique Score, Composite Score, Average Traffic, and LLM Referral Share. The contribution is meaningful but not dominant, so PR leads read Reading Behaviour directly instead of inferring it from GRP. When should PR teams prioritise Reading Behaviour over reach? For complex product launches requiring absorption, reputation-building campaigns aimed at analysts and decision-makers, and investor or partner reporting that depends on proving the message landed. Reach still wins for mass consumer announcements, brand-awareness campaigns, and time-sensitive news where visibility velocity matters most.
