You hit publish. Then the doubt creeps in — did I say that word too many times? Or barely enough? Reading it back never settles it. You wrote the thing; you're too close to it to see clearly. This tool works as both a keyword density checker and a keyword stuffing checker — free, with no account required.
What Is Keyword Density?
It's a ratio. Count how many times your target phrase appears, divide by total words, multiply by 100. That's it.
Use a keyword 15 times in a 1,000-word article and your density sits at 1.5%. Simple math — but the number tells you something real.
Search engines don't just check that a phrase exists on your page; they read how naturally it fits the surrounding sentences. Mention it too rarely and Google may never connect your page to that topic. Push it into every paragraph and you trip the opposite wire — the kind that buries pages or pulls them from results entirely. The goal isn't a perfect figure. It's writing that reads like a human wrote it.
How to Check Keyword Density of a Website
Paste Your Text
No setup, no login, nothing to install. Paste your draft straight into the text box above and the report builds in seconds. You can also type directly, and the tool updates in real time so you can adjust anything that looks off as you go.
Read the Numbers
You get more than a single percentage. The report shows your total keyword count, phrases grouped by length — single words plus two- and three-word combinations — each with a frequency count and density percentage, and an instant view of which words dominate your content,- Flags showing whether your target phrase appears in the title tag, meta description, H1, H2, and H3 - A tag cloud so you can see at a glance which words dominate the page. It's not just "here's a stat." It's a map of whether your keywords are landing in the right spots.
What Is a Good Keyword Density for SEO and Blog Posts?
No magic number exists — and anyone handing you a precise figure is oversimplifying. That said, years of SEO testing across the industry point to a zone that works:
| Density Range | What It Means | Should You Be Here? |
|---|---|---|
| Below 0.5% | Keyword barely registers | Probably too thin |
| 0.5% – 1% | Fine for shorter pieces | Situational |
| 1% – 2% | Reads naturally, well spread | ✅ This is your target |
| Above 3% | Starts feeling forced | 🚫 Back off |
For blog posts specifically, staying between 1% and 1.5% gives you a clear relevance signal without triggering over-optimization filters. Longer articles naturally drift toward the lower end of that band — more total words means each mention carries less weight as a percentage. Write for the reader first, then check the density after.
Keyword Stuffing — What It Is and Why It Always Backfires
Stuffing is the logic that says if one mention helps, thirty must help thirty times more. It doesn't. It does the reverse.
When Google's internal Search documentation leaked in 2024, it revealed an actual internal metric called KeywordStuffingScore — scaled from 0 (completely clean) to 127 (maxed out). Pages that drift too far up that scale get pushed down or cut from results entirely.
Watch for these patterns in your own content:
- The same phrase turning up in almost every sentence
- Keywords dropped into places where the grammar falls apart
- A wall of keyword lists at the bottom of the page that exists purely for crawlers
- Terms hidden in the code where only bots can see them
Recognize any of those? Run the page through the checker before you publish. Fixing it now is faster than untangling it after a ranking drop.
Where Your Keyword Should Actually Appear
Density in the body text is only part of the picture. For the strongest relevance signal, your target phrase should appear naturally in:
- Title tag — earlier in the title is better
- Meta description — this affects click-through rates more than most people realize
- H1 heading — your main heading should plainly say what the page covers
- First paragraph — an early mention helps search engines lock onto your topic
- Image alt text — a natural home for keyword variations without forcing them
- Internal link anchor text — when other pages on your site link here, the anchor text matters
Use this checker to confirm your body-text density is balanced, then double-check that your keyword also appears naturally in each of the spots above.
How to Check Competitor Keyword Density
Grab the content from a competing page that ranks well, paste it into the checker and you get their full breakdown in seconds including two-word and three-word phrase frequencies.
Pay attention to the phrases they repeat most. If a competing page holds a top-three position for your target term, their keyword distribution is a live signal of what Google currently rewards in that niche. Run your own page through the same check side by side and close the gaps where your density is lower; pull back where it's higher.

Why This Matters More in the Age of AI Search
Search isn't just ten blue links anymore. Around one in five Google searches now returns an AI summary, and 88% of those answers pull from three or more sources (Pew Research, 2025). With ChatGPT past 800 million weekly users and half of all shoppers already using AI-powered search (McKinsey, 2025), part of your audience is now a machine deciding what to quote. Research into Generative Engine Optimization shows that clear, quotable statistics raise your odds of being cited by an AI engine by roughly 40%. Balanced, naturally written content — exactly what this checker helps you confirm — is what both readers and AI engines reward.
