How Long Should a Blog Post Be? Data Over Dogma
How long should a blog post be? The answer depends on your keyword, your authority, and your SERP -- not a universal word count rule. Here is the data.
TL;DR — There is no universal ideal blog post length for SEO. The right length is whatever it takes to satisfy the search intent better than what currently ranks -- at a difficulty level your domain can actually win. For low-authority sites, chasing a word-count target is less important than writing the right post for the right keyword in the right order.
You Google "how long should a blog post be" and the top results all say something between 1,500 and 2,500 words. Some cite studies. Some cite averages. Most cite each other. You walk away with a number, open a Google Doc, and start writing toward a word count instead of toward a ranking.
That number is the wrong starting point. I have published posts at 800 words that reached page one in three weeks and posts at 3,000 words that stalled on page four. The length was not the variable that mattered. The variables that mattered were keyword difficulty relative to my domain, search intent alignment, and whether the post sat inside a cluster or floated alone. Word count was a trailing indicator of those decisions, not a leading one.
If you are running a low-authority SaaS blog and asking how long should a blog post be for SEO, the honest answer is: it depends on the keyword you picked and whether you should have picked it at all.
How long should a blog post be? The wrong question and the right one
The reason this question persists is that it feels actionable. Give me a number, and I know when to stop writing. The problem is that the number changes depending on the query, the SERP, and your site.
The studies that produce average word-count recommendations are real, but they describe correlations, not causes. Backlinko analyzed 11.8 million Google search results and found that the mean word count of a Google first-page result was 1,447 words. That is a descriptive finding about what exists on page one, not a prescription for what you should publish. Longer pages tend to earn more backlinks, cover more subtopics, and satisfy broader intent -- all of which help rankings. But the length itself is not the mechanism. The coverage is.
A 2,000-word post that pads its way to a word-count target with filler paragraphs will underperform a 900-word post that answers the exact query the searcher typed. Google's helpful content guidelines ask creators to evaluate whether their content "provides substantial value when compared to other pages in search results." Substantial value is about depth on the topic, not about hitting a minimum character threshold.
The right question is not "how many words should this post be?" The right question is: "what does page one look like for my target keyword, and how much depth do I need to beat it?"
What the SERP tells you about ideal blog post length
Instead of following a universal word-count rule, check the SERP for your specific keyword. The posts currently ranking are Google's revealed preference for what satisfies that query. Their length is a data point. Their structure is a better one.
Here is the process I use for every keyword before I decide on post length:
1. Search the keyword in incognito. Look at the top five organic results. Note the word counts (browser extensions like Detailed SEO or a quick copy-paste into a word counter will do).
2. Note the range, not the average. If page one has posts at 800, 1,200, 1,500, 2,200, and 3,500 words, the range tells you more than the mean. It means Google does not have a strong length preference for this query -- content quality and intent match matter more than word count.
3. Check what each post covers. Open the top three results. Scan headings. Identify which subtopics they address and which they skip. The gaps are your opportunity, and filling them determines your natural length.
4. Look at who is ranking. This matters more than word count for a low-authority site. If page one is dominated by DR-60 sites with 3,000-word guides, matching their word count will not help you outrank them. You need a winnable keyword first and a competitive length second.
The blog post length for SEO that works is the length that covers every subtopic the searcher needs, adds the angles competitors miss, and stops before it starts padding. That number is different for every keyword.
Blog post length by content type
Different content formats naturally land at different lengths. Trying to force a comparison post to 2,500 words or a glossary entry to 1,800 creates the kind of filler that Google's quality systems are designed to detect.
Here are the ranges I have found effective for low-authority SaaS blogs, based on what actually ranks in the niches I work in -- not universal benchmarks:
| Content type | Typical effective range | Why |
|---|---|---|
| Glossary or definition | 600 to 1,000 words | Searchers want a clear answer, not an essay |
| How-to tutorial | 1,200 to 2,000 words | Steps require detail, but padding kills scannability |
| Comparison or vs. post | 1,000 to 1,800 words | Structure carries the page; prose supports it |
| Strategy or framework | 1,500 to 2,500 words | Depth is the differentiator, but only if it earns each paragraph |
| Pillar or hub page | 2,000 to 3,500 words | Needs to cover the full topic and link to every spoke |
These ranges are starting points informed by SERPs, not rules. If your SERP analysis shows that a 900-word how-to outranks a 2,000-word one, follow the SERP. Google already tested both lengths with real users and picked the winner.
Why word count matters less than you think at low DR
Here is the part that most "ideal blog post length" guides miss: for a site under DR 15, the decision that determines whether you rank is not how long the post is. It is whether you targeted a winnable keyword, matched the search intent, and published within a topic cluster that compounds.
I have seen this pattern repeatedly. A founder writes a 2,500-word definitive guide targeting a KD-35 keyword. The post is thorough, well-structured, and longer than anything on page one. It stalls at position 30. Meanwhile, a 1,000-word post targeting a KD-6 keyword with forum-dominated results reaches page one in three weeks and starts sending relevance signals to the rest of the cluster.
The 2,500-word post was not too short. It was targeting the wrong keyword. No amount of word count would have compensated for the authority gap. This is the same principle behind winnability-first keyword research: the keyword selection matters more than the execution on any single post.
Blog post length SEO advice that ignores domain authority is advice designed for sites that already have it. If you are a bootstrapped founder with a DR-8 site, optimizing word count before you have filtered for winnability is solving problem number four while problem number one is still open.
The "longer is better" myth and where it came from
The idea that longer blog posts rank better has a specific origin. In the early 2010s, when thin content farms dominated search results, Google's algorithm updates (Panda, then successive core updates) penalized pages with very little substantive content. The takeaway became "write longer posts," and it was not wrong at the time. A 300-word post stuffed with keywords was clearly worse than a 1,500-word post that actually explained the topic.
But the lesson calcified into dogma. "Longer is better" became "aim for 2,000 words minimum," which became a word-count target divorced from the original reasoning. The original reasoning was: cover the topic thoroughly. Length was the side effect, not the cause.
Google's John Mueller has addressed this directly. In a Search Engine Journal interview, Mueller stated that word count is not a ranking factor and that there is no ideal word count from Google's perspective. The advice was to focus on what the user needs, not on hitting a number.
The correlation between length and rankings is real but confounded. Longer posts tend to cover more subtopics, attract more backlinks, and match broader intent queries. Those are the causal factors. If you can cover every subtopic and match intent in 1,100 words, adding 900 words of filler will not improve your ranking. It may hurt it by diluting the signal-to-noise ratio.
How to determine the right length for your next post
Here is the practical framework I use before every post on a low-authority site. It takes five minutes and replaces any generic word-count rule.
Step 1: Confirm winnability. Before you think about length, check whether your domain can realistically rank for this keyword. If the SERP is locked by high-authority sites, word count is irrelevant. I covered the full winnability check in how low-authority sites actually rank.
Step 2: Analyze the top three results. Note their word counts, heading structures, and subtopics. These are your benchmarks -- not averages from a cross-industry study, but the specific pages you need to beat.
Step 3: List the subtopics you must cover. Every subtopic the top results cover is table stakes. Every subtopic they miss is your edge. Your post length is determined by covering both sets thoroughly and stopping there.
Step 4: Write to completeness, not to a count. Draft until you have covered every subtopic on your list. If that takes 900 words, stop at 900. If it takes 2,200, stop at 2,200. Then edit for tightness. Cut every sentence that does not serve the searcher. The final word count is an output of the process, not an input to it.
Step 5: Fit it into your calendar. The post's length affects how long it takes to produce, which affects your publishing cadence, which affects your compounding velocity. A 3,000-word post that takes five days to write is not inherently better than two 1,200-word posts targeting adjacent keywords in the same cluster. At low DR, publishing velocity within a cluster often matters more than depth on a single page. This is the trade-off that a content strategy built around clusters makes explicit.
What this means for your content calendar
The question of how long should a blog post be is really a planning question disguised as a writing question. And planning questions belong in your content calendar, not in your drafting process.
When you build a content calendar for a low-authority site, each post needs three things decided before you start writing: the target keyword, the winnability score, and the content format. The format implies a length range. A comparison post targeting a KD-4 keyword does not need 2,500 words. A pillar page anchoring a whole cluster probably does.
Making these decisions at the calendar stage -- before you open a blank document -- prevents the most common failure mode I see: founders spending a full day on a 3,000-word post for a keyword they cannot rank for, while three winnable keywords sit unwritten because the calendar treated every post as equal effort.
This is the planning problem Boomranq solves. When you give it a product description, it does not just pick keywords. It scores them for winnability, clusters them, and sequences a 30-day calendar where each post is sized to its role in the cluster. Spokes are concise. Pillars are comprehensive. The calendar reflects the actual effort each post requires, not a one-size-fits-all word-count target.
The one-sentence answer
How long should a blog post be? As long as it needs to be to beat what currently ranks for your target keyword -- and not a paragraph longer. For a low-authority site, the word count that matters most is zero: the words you did not waste on an unwinnable keyword. Get the keyword right, match the intent, write to completeness, and let the SERP set the length. That is data over dogma.
