What is the Keyword Density Checker?
The Keyword Density Checker analyzes a block of text or a live web page and reports which words and phrases appear, how often, and as what percentage of the total word count — in one-word, two-word, and three-word combinations. It shows you a page the way an early-stage relevance algorithm reads it: pure word statistics.
Modern SEO doesn't rank pages by density formulas, but the tool remains genuinely useful as a **reality check on focus**. It answers a simple question: does this page talk about what I claim it's about — and does it drift off-topic or repeat one phrase to the point of looking manipulative?
How to use it
1. Choose your input mode: paste text directly, or enter a URL to analyze the live page.
2. Run the analysis. The tool lists keywords with counts and density percentages.
3. Read the **top three-word phrases** first — they best reveal a page's actual topical focus.
4. Sanity-check two things:
- Is the intended topic dominant? If you wrote a page about "robots.txt generators" and that phrase barely registers, your page is drifting.
- Is anything suspiciously dense? A single term above roughly 4–5% of the text usually reads as keyword stuffing to both users and algorithms.
5. Edit accordingly: naturally weave the target phrase in, or thin out the repetition.
A note on "ideal density"
There is no magic percentage. Google's language understanding is far beyond counting — it evaluates meaning, entities, and coverage of a topic. Use density as a guardrail (avoid stuffing, confirm focus), never as a target to hit. A well-written page for a given topic almost always lands in a natural 1–2.5% range for its main phrase without anyone trying.
FAQ
What density should I aim for?
None specifically. If your writing is natural and on-topic, density takes care of itself. Only intervene if a phrase is far too high (stuffing) or a key phrase is absent.
Can I analyze a competitor's page?
Yes — pasting a competitor's top-ranking page alongside your draft shows which subtopics they cover that you don't. The differences are often more valuable than the matches.
Does it count stop words?
Yes, which is why the multi-word phrase lists are the useful part — they filter the noise automatically.
Will keyword stuffing get me penalized?
Aggressive stuffing can trigger spam systems or simply reads terribly, which drives visitors away. Either way, don't.
