Why Showing Estimated Reading Time Helps Your Content
A reading time estimate is the small "7 min read" line near the top of an article. The Reading Time Estimator calculates it, and the reason it works is about expectations rather than information.
It sets an expectation before the commitment
A reader deciding whether to start an article is weighing an unknown cost. A scroll bar gives a vague sense of length; a number gives a precise one.
What that does is let someone choose deliberately - read it now, save it for later, or skip it. All three are better outcomes than starting and abandoning, which is the result when the length is a surprise. It is the same courtesy as a video showing its duration before you press play.
It also makes a long piece feel chosen rather than imposed. Twelve minutes stated upfront reads as substantial; twelve minutes discovered at minute four reads as interminable.
The arithmetic, and which number to use
Count the words, divide by a reading speed, round up. The entire question is the speed.
Adult silent reading of general prose averages around 240 words per minute, with wide individual variation. Most publishers use something between 200 and 265. Medium's well-known implementation uses 265.
Lower numbers are the safer choice. Overestimating the time costs you nothing - the reader finishes early and feels efficient. Underestimating leaves them still reading past the promised end, which is mildly irritating and undermines the figure. So 200 to 240 is a reasonable default, and technical material deserves the lower end because people re-read.
Worth accounting for: images and code blocks are not words but do take time, so a heavily illustrated piece reads longer than its word count suggests. A common adjustment adds around twelve seconds for the first image and a little less for each after.
When it backfires
On short pieces, where "1 min read" draws attention to slightness. Below two or three minutes, omitting it is usually better.
On reference pages, where nobody reads top to bottom. A cheat sheet has no reading time in any meaningful sense.
When it is wrong. A figure that is consistently half the real time trains readers to ignore it.
It is not a ranking factor
Google does not read your reading-time label, and showing one does not affect rankings. What it may affect is whether someone starts reading - and how long they stay is a behaviour search engines do notice. That is an indirect benefit and worth being honest about.
Common questions
Where should it go?
Near the title, with the date and author. Readers look for it before the first paragraph.
Should I count headings and captions?
Include them. They are read, if quickly.
What speed for non-native readers?
Slower - which is another argument for a conservative figure.
Does it help SEO?
Not directly. It helps people decide to read, which helps everything downstream.
Is word count the same as reading time?
Related, not identical. The Word Counter gives the count; the time depends on the speed you assume.
