How long should a blog post be for SEO? The question gets asked as if there were a number on a dial somewhere, and every few years a new figure circulates as the answer: 1,500 words, then 2,000, then 3,000. Writers pad to the target, readers scroll past the padding, and the posts that win keep being the ones that answer the question best.
The data is real. The conclusion people draw from it usually is not. This post looks at what the most-quoted figure actually says, why it misleads, and how to set length per article instead of per blog.
What the data says
The figure most writers have seen comes from Semrush’s State of Content Marketing 2022 report, summarised by Margarita Loktionova on 28 September 2022: Semrush’s guide to blog post length.
| Finding | What it says | What it does not say |
|---|---|---|
| Page views | Posts with 3,000+ words get 138% more page views than those under 500 words, on average | That adding words to a post will add views |
| Backlinks | Longer content also tends to earn more backlinks | That length causes the links |
| Semrush’s own conclusion | Success comes from quality and topic coverage, “not necessarily a specific length” | Any target word count |
| No published word-count requirement | Anything either way about length as a factor |
Read the third row twice. The source of the most-quoted length statistic in SEO does not conclude that you should write longer. It concludes that coverage matters, and that length is what coverage sometimes looks like.
Why long posts look like they win
Correlation, not causation. A 3,000-word post is rarely a 500-word post with extra sentences. It is usually a different kind of article on a different kind of topic: a broad guide, a comparison of many products, a tutorial with many steps. Those topics have bigger audiences and more reasons for other sites to link to them.
Compare that with the typical 500-word post: a news note, a short update, a narrow answer. Those topics attract fewer searches and fewer links whatever their length. The 138% gap is at least partly a gap between topic types, and you cannot close it by stretching a narrow topic until it is long.
The backlink pattern follows the same logic. Comprehensive guides are linkable because they are useful as references. A padded post is not more useful as a reference; it is harder to use as one.
Let the query set the length
The better question is not how long a post should be but what the searcher needs to finish their task. That depends on the query, and the results page tells you. Search the term, open the top results and note what they cover and how deep they go.
- Quick-answer queries (a definition, a conversion, a date) are best served short. The answer should sit in the first lines, and a long preamble pushes it down.
- How-to queries need as many words as the steps require. Cutting a step to save words makes the post worse.
- Comparison and “best” queries tend to be long because each option needs evidence. Length here is a by-product of covering the options properly.
- Broad guides are long by nature, and are often better split into a pillar plus supporting posts.
Matching the query is the subject of our guide to search intent, which covers how to read the results page for the type of answer Google is rewarding. Reading the results takes five minutes and tells you more about the right length than any industry average.
How long should a blog post be for SEO in practice?
A working process that avoids both padding and thin pages:
- Outline before you count. List the sub-questions a searcher would have, using the top results and related questions for evidence.
- Write each section to completion. A section is done when it answers its question, not when it reaches a quota.
- Cut on the edit. Remove restated points, generic introductions and sentences that would fit any article on any topic.
- Check the gaps. If competing pages cover a sub-question you skipped and searchers need it, add it. If they cover it only to add bulk, leave it out.
Length then becomes an output. Some posts will land at 700 words, some at 2,500. A blog where every post is exactly 1,500 words is a blog written to a template rather than to its readers.
It also helps to think in terms of the whole site rather than the single post. A narrow question that needs 600 words is better as its own page linked from a pillar than as a section buried inside a 4,000-word guide. How many such pages a site needs before traffic arrives is covered in how many blog posts you need to get traffic.
Where padding costs you
Padding is not neutral. A reader who has to scroll past three paragraphs of background to reach the answer is more likely to go back and pick another result. Padding also dilutes the page’s focus, which makes it harder to tell what the page is primarily about, and it can push a site towards several long pages that overlap and compete with one another.
If you already have long posts that are long only because of a word-count target, editing them down is a legitimate improvement. Our guide to content pruning covers when to trim, merge or remove pages that are not earning their place.
The limits of the length data
The honest limitation is that the Semrush figure is an average across many posts, many sites and many topics. It cannot tell you how long your post on your topic should be, and it cannot separate the effect of length from the effect of topic, authority and promotion. Treat it as a description of what successful content often looks like, not a recipe.
You can study length in your own niche without leaning on averages. In the database explorer, filter to your niche and sort by estimated organic traffic, then open the strongest sites and look at the posts that rank for queries like yours. That is a method, not a target. You are looking at how deep they go on each kind of query.
You will usually find a range rather than a number: short pages for narrow questions, long pages for broad ones, and very little padding on the sites that rank consistently. That pattern is the real answer to the length question. Write to the query, edit hard, and let the word count fall where it falls. More on measurement sits in the data archive.
Frequently asked questions
Is there an ideal blog post length for SEO?
No single ideal exists. Long posts earn more page views on average, but that reflects bigger topics. Write as long as the query needs and cut the rest.
Is word count a Google ranking factor?
There is no published word-count requirement from Google. What matters is whether the page answers the query well and covers what searchers need.
How many words should a blog post be for SEO?
Look at the top results for your query. A quick answer may need a few hundred words; a comparison or full guide may need several thousand.
The takeaway Long posts win because they tend to cover bigger topics, not because they are long. Read the results page, write to the query and edit out the padding.
