SEO Word Counter & Keyword Density Checker
Paste your draft below to see word count, reading time, and how often any keyword repeats — instantly, as you type.

Why word count and keyword density still matter
Word count by itself was never a Google ranking factor, and it still isn't. What it correlates with is whether a topic has been covered thoroughly enough to actually answer the searcher's question. A 300-word post on "how search engines index websites" is almost never going to out-compete a 1,500-word post that walks through crawling, rendering, and indexing with real examples — not because Google rewards length directly, but because the longer piece is more likely to actually be complete.
Keyword density is the older, blunter cousin of this idea. It used to be treated as a formula to hit — repeat the keyword until it's 2% of the text. Modern search engines understand language well enough that stuffing a keyword unnaturally can hurt readability without helping rankings at all, and in some cases triggers spam-pattern detection. The number is still useful, but only as a sanity check, not a target to engineer toward.
Rough length guide by content type
| Content type | Typical range |
|---|---|
| Quick answer / definition post | 300–600 words |
| Standard how-to guide | 800–1,500 words |
| In-depth / pillar guide | 1,800–3,000+ words |
| Product or tool comparison | 1,200–2,000 words |
These are starting points, not rules. The right length is however long it takes to fully answer the query without padding — a guide artificially stretched to hit a number reads worse than a shorter, tighter one.
How to use this tool
Paste your draft into the box above to see live word count, character count, sentence count, and an estimated reading time based on an average adult reading speed of 200 words per minute. Then type any target keyword into the second box to see exactly how many times it appears and what percentage of your total word count that represents.
Reading keyword density sensibly
Under 0.5% usually means the keyword barely appears, which can make it harder for search engines to understand what the page is actually about, especially if it's also missing from the title and headings.
0.5% to 2.5% is a comfortable, natural range for most content — the keyword shows up often enough to signal relevance without feeling forced.
Above 3% is where text often starts to read as repetitive to a human reader, which is usually the real problem, whether or not it technically affects rankings.
Frequently asked questions
- Is there an ideal word count for SEO?
- No single number works for every topic. The better question is whether the piece fully answers the query it's targeting — length should follow from that, not the other way around.
- Does higher keyword density improve rankings?
- Not reliably, and pushing density too high can read as keyword stuffing, which search engines are generally good at detecting and can penalize.
- Should I count words in headings and captions too?
- For a rough content-depth check, total visible word count including headings is fine. For keyword density specifically, it's more useful to also check whether the keyword appears in the title and at least one heading, not just the body count.
- Is this reading time estimate accurate for everyone?
- It's an average based on roughly 200 words per minute for adult silent reading. Technical or code-heavy content is usually read more slowly than this estimate suggests.
