How Long Should a Blog Post Be for SEO?

There is no ideal word count, and word count is not a ranking factor. The right length is however many words it takes to answer the query completely and then stop. In practice that means roughly 300–800 words for a direct factual question, 1,000–2,000 for a how-to or comparison, and 2,000–3,000+ for a pillar page covering a whole topic.

Why "longer ranks better" is a misreading

You've seen the studies: average word count of a page-one result is 1,400 words, or 1,900, depending on which one you read. The correlation is real. The conclusion drawn from it usually isn't.

Google's own search advocates have said repeatedly that word count is not a ranking factor. What the correlation reflects is that competitive queries tend to require thorough answers, and thorough answers tend to be long. Length is a downstream symptom of covering a subject properly, not the cause of ranking.

Padding a 600-word answer to 1,800 words gives you a 600-word answer with 1,200 words of filler in front of it. That's worse for the reader, worse for the featured snippet, and worse for AI systems trying to extract a clean passage — one of the few things measurably associated with reduced AI visibility is bloat and keyword repetition.

The test that actually matters: could you delete a paragraph without losing information? If yes, delete it. Repeat until the answer is no.

Set length from intent, not from a target

Search intent determines the shape of the answer, and shape determines length. Four cases:

Informational, direct question — "what is a canonical tag", "how many backlinks do I need". Someone wants a fact. Lead with a 40–60 word answer, explain the mechanism, cover the two or three follow-up questions. 300–800 words, and forcing it to 2,000 actively hurts you, because the answer gets buried below the fold where the snippet extractor won't find it.

Informational, process or comparison — "how to get your site indexed", "guest posting vs link exchange". There are steps, trade-offs, and edge cases. 1,000–2,000 words is where these naturally land.

Commercial investigation — "best backlink tools", "is it worth paying for backlinks". People are deciding how to spend money and want the caveats. 1,500–2,500 words, mostly because the honest version has to cover several options.

Pillar / topic overview — the hub of a topic cluster. Covers the whole subject at readable depth and hands off to the spokes. 2,000–3,000+ words.

Transactional — pricing, product, sign-up. Short. Clarity and specifics beat prose; an AI agent evaluating your product needs parseable facts, not paragraphs.

The method: read the SERP, then decide

Skip the word count target. Do this instead, and it takes fifteen minutes.

Search your query and open the top five results. Not to copy their length — to see what format Google is rewarding. If page one is all 500-word direct answers, a 3,000-word essay is answering a question nobody asked.
List every sub-question they answer between them. Combine the lists. Add the People Also Ask box and the "related searches" strip.
That combined list is your outline. Your length is whatever it takes to cover it plus whatever you can add that none of them have — your own data, a worked example, the caveat they all skipped.
Cut everything not on the list. Definitions of terms your reader already knows, history nobody asked for, and the three-paragraph windup before the answer.

This produces a defensible length every time, because it's derived from what the query actually requires rather than from an average.

The 40–60 words that matter most

Whatever the total, the opening passage does disproportionate work.

Google's featured snippets pull from short, self-contained passages that answer the question directly. AI answer engines do effectively the same thing — they run a few searches, lift the cleanest passage, and name two or three sources. Both reward the same structure: a direct 40–60 word answer immediately under a heading that matches the query, before any context or preamble.

A 2,500-word article that buries its answer in paragraph nine loses to an 800-word article that leads with it. This is the single highest-leverage formatting decision in a post, and it's independent of length.

The same principle applies internally: descriptive H2s, short paragraphs, and an FAQ block of real question-and-answer pairs give both systems clean passages to extract. Length without structure is just a wall.

When the answer is "cut, not add"

Some of the most valuable editing work is subtractive:

Thin content is a real risk; padded content is a different one. Google's guidance targets unhelpful, unoriginal content — a padded post is unhelpful in a way a short, complete one isn't.
Two mediocre 1,500-word posts on the same intent should be one strong post plus a redirect. That's keyword cannibalisation, and merging usually beats writing a third.
A page that slipped from position 6 to 15 more often needs updating and tightening than expanding. Refreshing a near-winner is typically faster than ranking anything new.
If your introduction is three paragraphs of context, the article starts in paragraph four and everything before it is costing you the snippet.

What to do instead of counting words

If you're inclined to optimise something numeric, these matter more:

How many of the query's sub-questions you actually answer. Coverage of the question space is what topical authority is made of.
How fast the answer appears — measured in words from the top of the page, not scroll depth.
How many internal links point at the page. Two or three contextual links from strong related posts on publication day is worth more than 800 extra words. See what internal links do.
How many external sites link to it. For anything competitive, this is the binding constraint, and no amount of length substitutes. If that's your bottleneck, Backlinkster pairs you with a site owner in a related niche for a one-for-one swap, each link inside real content and verified live by code.

Frequently asked questions

How long should a blog post be for SEO? Long enough to answer the query completely and no longer. Roughly 300–800 words for a direct factual question, 1,000–2,000 for a how-to or comparison, 1,500–2,500 for commercial "best of" content, and 2,000–3,000+ for a pillar page covering a whole topic. Derive it from the sub-questions the query requires, not from a target.

Is word count a Google ranking factor? No. Google has stated repeatedly that word count is not a ranking factor. Studies showing page-one results averaging 1,400–1,900 words reflect that competitive queries need thorough answers — length is a symptom of thoroughness, not the cause of ranking.

Can a short blog post rank well? Yes. For direct factual queries, a well-structured 400-word page that answers the question in its first passage regularly outranks longer articles, and is more likely to win the featured snippet because the answer is easy to extract.

Does longer content get more backlinks? Long-form content does attract links more often, but the driver is usually what makes it long — original data, comprehensive coverage, useful frameworks — rather than the word count itself. A 3,000-word article with nothing new in it attracts nothing.

How long should a pillar page be? Typically 2,000–3,000 words or more, because it summarises every sub-topic before linking to the page that covers each in depth. It should still be genuinely readable on its own; a pillar that's only a table of contents ranks for nothing.

Should I make old posts longer to improve rankings? Only if they're missing answers readers need. Updating for accuracy, tightening the opening so the answer appears sooner, and adding internal links usually moves a slipping page more than adding words does.

The bottom line

Nobody ranks because of a word count. Read the SERP, list every sub-question the query implies, answer all of them plus something nobody else covered, then stop — and put a direct 40–60 word answer at the very top regardless of how long the rest turns out to be. If you're deciding between adding 800 words and adding three internal links from your strongest related posts, add the links.
