Writing a BLUF Answer

Last updated: June 24, 2026

BLUF stands for "Bottom Line Up Front," and it's the single highest-leverage content fix you can make. AI engines extract the first 40–80 words of a page as the quote candidate. If the answer to the target prompt isn't in that window, you don't get cited. This article shows you how to write one.

What BLUF demands

Lead every page with a 40–80 word extractive summary that directly answers the target prompt, and include the current month and year as a freshness signal. This is the paragraph AI engines will quote, so it has to carry the answer on its own.

The 10-second test

Read only the first paragraph of your priority page and answer yes or no:

  1. Does it directly answer the target prompt?

  2. Is it 40 to 80 words?

  3. Does it include the current month or year?

Any "no" is a BLUF gap.

A good BLUF

Target prompt: "prepaid vs postpaid mobile plans"

"Prepaid vs. postpaid in Germany, April 2026: Prepaid plans are cheaper, contract-free, require no credit check, and cap your spending, ideal for budget-conscious or short-term users. Postpaid plans offer more data, added flexibility, and loyalty discounts, but require credit checks, contracts, and carry cancellation fees. Choose prepaid if you want cost control; choose postpaid if you're a heavy user who values convenience over savings."

What makes it work: it answers the question in the first clause, it's structured as a comparison (matching the prompt's intent), it ends with a decision rule ("choose X if..."), it's stamped with the current month and year, and it's under 80 words.

A buried BLUF (the anti-pattern)

"When it comes to selecting a mobile connection in Germany, the choice between prepaid and postpaid can be a daunting task. Both options have their advantages and drawbacks, and the right choice depends on your specific needs and circumstances..."

This is 40 words of preamble with zero extractable information. AI engines quote nothing from it because there's nothing to quote.

The 40–80 word template

[Direct answer to the target prompt, in one or two sentences.]

As of [Month Year], [key differentiator or stat].

[Decision rule or "best for" statement.]

[One-line caveat or counter-case, optional.]

Fill in the blanks, hit 40-80 words, and ship.

What to do with the marketing intro you're deleting

Move it to the bottom of the page, or delete it. Don't keep it "for context." The first paragraph is worth far more than the last in AI citation. Protect that real estate.

Special case: topics that need context

Some prompts genuinely need a one-sentence scope before the answer. Pattern: "For B2B SaaS companies with $1M+ ARR: [40–80 word BLUF follows]." Keep the scope statement to one sentence, then deliver the BLUF.

Do this now

Open your priority page, delete the first paragraph, and rewrite it using the template. Hit 40-80 words, include the current month and year, ship today, and re-audit in four weeks.
