Where attention
leaves the page.
Reading patterns are clues, not laws. Use viewport behavior and scroll observations to ask better questions about your copy.

F-pattern, Z-pattern, and the limits of both
The F-pattern describes a common scan in text-heavy layouts: readers may take in an upper line, scan a shorter line below, then move down the left edge. A Z-pattern describes a different route across a sparse composition, often from a top edge toward a prominent action. Neither pattern is a universal map of the eye.
Task, prior knowledge, typography, culture, device, and visual hierarchy all affect where someone looks. A pattern observed on one page cannot be assumed on another. Treat these labels as prompts for inspecting your own layout, not benchmarks that establish how every visitor reads.
Desktop and mobile do different work
Desktop can place navigation, proof, and an action in the same view. That does not guarantee each element receives attention: competing columns can also split it. On mobile, narrower lines and a taller page change the order in which content appears, while sticky elements may consume meaningful screen space.
Review actual pages at common viewport sizes and with realistic content. Check whether the first screen identifies the offer, whether a key qualification is pushed below the fold, and whether a fixed bar obscures a form or a paragraph. The fold varies by device and browser; it is a range, not a single pixel.
Find the point where the argument loses momentum
In a long sales letter, scroll-depth reporting can show how far a group of visitors travels, but it cannot establish whether they read or understood every section. Fast scrolling, returning visits, and different landing points can all change the picture. Segment by device and traffic source before interpreting a drop.
A sharp decline near a section can guide a closer review. Look for an abrupt change in subject, a repetitive claim, an unanswered cost question, or a demand for commitment before the offer is understood. Pair the observation with interviews or a controlled revision before attributing the drop to a particular sentence.
Give the eye a reason to return
A useful subhead carries the argument forward even when a reader scans. It can name a question, explain a consequence, or introduce proof. A series of generic labels such as “Benefits” and “Features” may organize a page without telling a skimmer why the next section matters.
There is no magic number of words or fixed spacing that resets attention for everyone. Try a cadence that reflects changes in the argument, then examine readability at both narrow and wide widths. If a subhead promises an answer, the section beneath it should deliver that answer promptly.
