Reading Behaviour Online
Date: 2026-08-17
People scan rather than read, in predictable patterns, looking for what they came for. Writing that assumes linear reading fails against how the page is actually processed — which is a design problem as much as a writing one.
Online reading is task-driven scanning. People arrive with a goal, sample the page for evidence it can be met, and read only what looks relevant.
This is rational behaviour, not laziness. With a page of unknown value, sampling before committing is the efficient strategy.
The scanning patterns
F-PATTERN
▬▬▬▬▬▬▬▬▬▬
▬▬▬▬▬▬
▬▬
▬
→ text-heavy pages with poor
formatting
→ the RIGHT side and LOWER text go
unread
LAYER-CAKE
▬▬▬▬▬▬▬▬ heading
... skip
▬▬▬▬▬▬▬▬ heading
... skip
→ GOOD scanning. What well-structured
content produces
SPOTTED
scanning for a specific word —
a price, a size, a brand
→ filtering, not reading
The F-pattern is a symptom, not a target. It appears when content isn’t structured enough to scan properly — the reader falls back to sampling line beginnings. Good headings and lists produce the layer-cake pattern instead.
What this means for writing
FRONT-LOAD
the important word first — people
read the first two words of a line
"Delivery costs" not "Information
about delivery costs"
INVERTED PYRAMID
conclusion first, detail after
→ they may stop at any point
ONE IDEA PER PARAGRAPH
scannable, and skippable
DESCRIPTIVE HEADINGS
a heading is a navigation label,
not a title
"Returns take 5 working days"
beats "Returns"
LISTS AND TABLES
for anything enumerable or
comparable
BOLD THE LOAD-BEARING PHRASE
sparingly — bolding everything
bolds nothing
Descriptive headings do double duty, since they’re also how screen reader users navigate — Screen Readers.
Length
Length isn’t the problem; unstructured length is.
1,200 WORDS, STRUCTURED
headings, lists, front-loaded
→ scannable, people find their bit
300 WORDS, UNSTRUCTURED
one dense block
→ skipped entirely
Cutting a wall of text in half produces a smaller wall of text. Structuring it is the fix — Content Design.
Where people do read properly
The scanning finding is often over-generalised:
THEY READ CLOSELY
the product description of something
they're about to buy
ingredient lists, for a reason
reviews, especially negative ones
terms that affect them — returns,
subscription commitment
anything they've decided matters
High-intent readers on a decision page read carefully. Stripping a product description to three bullets because “nobody reads” removes the information a committed buyer needed — Product Page Design.
The distinction is intent, not medium. Scanning happens when assessing relevance; reading happens once relevance is established.
Mobile
NARROWER more lines per paragraph
→ chunk harder
NO HOVER nothing revealed on hover
— Mobile Interaction Patterns
LESS VISIBLE the "fold" is smaller,
and scrolling is cheap
→ put the answer high,
don't fear length
INTERRUPTED they may return later
→ structure lets them
re-find their place
See: Mobile Interaction Patterns
“Above the fold” matters less than it did — people scroll readily. What matters is whether the top of the page signals that the answer is below, which is a job for the first heading.
Testing it
FIVE-SECOND TEST show the page briefly,
ask what it was for
→ tests the scan, not
the read
HIGHLIGHTER TEST ask participants to
mark what they'd
actually read
EYE TRACKING precise, expensive,
rarely necessary
SCROLL DEPTH + is the content reached
TIME — Scroll Tracking
See: Engagement Metrics
The five-second test is the cheapest and most revealing — if someone can’t say what a page is for after five seconds, the scan has failed regardless of how good the prose is.
