Flesch reading ease: formula, score chart and how to improve it
The Flesch reading ease formula explained with a worked example, a score chart from 0 to 100, the Flesch-Kincaid grade level, and 7 ways to raise your score.
Key takeaways
- Google says it has no preferred word count. Length matters only because it tracks how fully a page answers the search.
- Backlinko’s study of 11.8 million results found the average page-one result had about 1,447 words, but that varies hugely by query.
- The fastest way to size a post: check the top 5 results for your keyword, take the typical range, and cover the topic better rather than longer.
Short answer: as long as it takes to fully answer the search, and no longer. Google has said plainly that it does not prefer a word count. Yet length still correlates with rankings, because thorough pages tend to cover more of what searchers want. This guide gives you practical word count ranges, a five-minute method for sizing any post, and how to keep keyword use natural.

Does word count matter for SEO?
Not directly. Google’s guidance on helpful content asks writers whether they are aiming for a particular word count because they heard Google likes it, and answers that it does not. What Google measures is whether the page satisfies the person searching.
Length still shows up in studies. Backlinko’s analysis of 11.8 million search results found the average page-one result contained about 1,447 words. The likely reason is not length itself: longer pages tend to answer follow-up questions, earn more links and match more long-tail searches.
Recommended word counts by content type
| Content type | Typical length | Why |
|---|---|---|
| Quick answer ("how many sats in a bitcoin") | 600–1,200 | Answer first, then context and a table |
| Calculator or tool page | 400–1,000 around the tool | The tool is the answer; text explains inputs and results |
| How-to guide | 1,200–2,000 | Steps, examples, mistakes, FAQs |
| Formula or "how to calculate" post | 1,000–1,800 | Formula, worked examples, variations |
| Comparison or "X vs Y" | 1,500–2,500 | Both options, a table and a verdict |
| Ultimate guide or pillar page | 2,500–4,000+ | Covers a whole topic and links to cluster posts |
| Product or category page | 300–800 | Buyers want specs, price and proof, not essays |
How to find the right length for your keyword
- Search your keyword in an incognito window and open the top 5 organic results.
- Paste each article into a word counter and note the counts. Ignore forums and videos.
- Take the middle of the range. If results run 900, 1,300, 1,400, 1,600 and 3,200, plan on about 1,400.
- List the subtopics every top page covers, then the ones none of them cover well. The gaps are where you win.
- Write, then cut. Remove anything that does not help the reader act on the answer.
Why low-competition keywords need fewer words
For new sites with a low domain rating, the best opportunities are specific long-tail searches where the ranking pages are thin forum threads, old posts or pages that only partly answer the question. You rarely need 3,000 words to beat them; you need a clearer, more complete answer with original examples. Put the direct answer in the first two sentences, then expand.
Keyword density: how often to use your keyword
There is no magic percentage, and Google lists keyword stuffing as spam. A practical pattern:
- Main keyword in the title tag, H1 and first 100 words.
- Main keyword or a close variant in one or two H2s.
- Related phrases (synonyms, questions, units) spread naturally through the body.
- A density above roughly 2 to 3% for a single phrase usually reads as forced.
The word counter lists your most repeated words and phrases so you can spot overuse before you publish.
Length is not the only thing: titles and readability
A long post that nobody clicks will not rank for long. Write a title that matches the search and promises a specific answer, then preview it in the SERP snippet preview to make sure it is not cut off. Track the result in Search Console with our guide to CTR.
Finally, make long content easy to scan: short paragraphs, descriptive subheadings, tables and a Flesch reading ease score of 60 or more. Check it with the readability checker.
FAQ
What is the ideal blog post length for SEO?
There is no single ideal length. Most informational posts that rank on page one fall between about 1,000 and 2,500 words, but quick answers and calculators can rank with far fewer words. Match the depth of the pages already ranking.
Does Google count words?
Google has said word count is not a ranking factor. Its helpful content guidance specifically asks whether you are writing to a word count because you think Google prefers one, and says it does not.
How many words is a 5-minute read?
About 1,100 to 1,200 words, at an average adult reading speed of roughly 230 to 240 words a minute.
What is a good keyword density?
There is no target. Use the main keyword in the title, H1, first paragraph and a few headings, then write naturally. If a phrase appears more than about 2 to 3 times per 100 words it usually reads as stuffing.
