How to Write Introductions That Hook

The introduction has one job measured in seconds: convince the just-arrived searcher they're in the right place — before the back button, which sits closer than your second paragraph. Search traffic makes this brutal and simple: the visitor came with a question, your intro either signals "answered here, competently" or they pogo-stick to the next result (the satisfaction physics at its sharpest point). Here's the intro craft for search content: the pattern that works, the openers that kill, and the format variations.

The pattern: confirm, deliver, promise

Three moves in three-to-five sentences: confirm the question — the reader's problem named in their terms, first sentence or second (the query's language appearing early is both reader-signal and relevance-signal, per the first-hundred-words rule — earned naturally by simply addressing the topic); deliver value immediately — the core answer, the headline number, the verdict-in-brief (the front-load doctrine: readers who get value in the intro stay for the depth; withholding it "for suspense" is how informational content manufactures bounces — and the answer-first shape is precisely what snippet extraction wants from your opening); promise the rest specifically — what the full piece adds ("the five fixes, the decision tree, the mistakes to avoid") in one scannable sentence that doubles as the piece's roadmap.

The openers that kill (the deletion list)

The patterns editors cut on sight, per the checklist: the throat-clear ("In today's fast-paced digital world...") — three sentences of topic-adjacent weather before anything happens; the dictionary open ("Webster's defines...") and its cousin the obvious-definition open for expert audiences; the rhetorical question stack ("Struggling with X? Wondering about Y?") — one can work, three is a tic; the autobiography nobody ordered — context about you before value for them (the story-led open is legitimate craft with rules; the rambling preamble isn't it); and the suspense withhold — "we'll reveal the answer below" in content whose readers came for the answer. The shared disease: sentences that could open any article on the topic, which is the test — an intro's second sentence should be unusable on a competitor's piece.

Format variations on the pattern

Listicles: confirm + the selection promise ("tested/ranked how") + the top pick early where intent is decisive. Comparisons: the verdict-in-brief up top, always — comparison readers who can't find the answer fast assume it's buried for affiliate reasons. How-tos: confirm + outcome + the requirements line (time, tools, difficulty). Landing pages: a different discipline entirely — the formula toolkit's territory, where the "intro" is the hero section and the physics are persuasion.

Frequently asked questions

How long should an introduction be?

Three to five sentences for most posts — long enough for the three moves, short enough that the first H2 is visible without scrolling on mobile (the practical test). Pillar pages stretch to a short paragraph-plus-roadmap; nothing editorial needs the 300-word intro that briefs its own article.

Should the intro contain the primary keyword?

It will, if move one is done honestly — naming the reader's question in their language is the keyword's natural first appearance, per the standing write-for-the-topic rule. Forcing an exact-match sentence where the natural phrasing differs is the tail wagging the paragraph.

Does giving the answer away up front hurt engagement or ad metrics?

The data says the opposite for search content: answer-first pages earn longer engagement (trust converts to depth-reading, per the promise-delivery findings) while withholding earns pogo-sticks. The revenue exceptions (suspense-monetised formats) know who they are; informational content isn't them — its returns come from satisfied readers and the authority they compound (our opening line's shorter).
