Is this keyword density checker really free?

Yes — enter any page URL and get the full word/phrase analysis, no signup, no payment.

What is the ideal keyword density for SEO?

There isn't one — Google doesn't publish or confirm a target. Aim for natural writing where your topic and related terms appear organically. If forced to pick a comfort zone, most well-written pages land between 0.5% and 2.5% for their main keyword.

Can I paste my text, or only check a live URL?

Both — paste your text directly for an instant in-browser analysis, or enter a live page URL and the tool fetches and analyzes the published content. For length checks while you write, pair the Word Counter.

Why are "the", "and", "of" topping my results?

Those are stop words — the most common words in English. Use the stop-word filter to hide them and see your real content words.

Does keyword stuffing still get penalized?

Blatant stuffing is a spam signal Google has filtered for over a decade. More importantly, it repels human readers — which kills the engagement signals that actually matter.

Should I match a competitor's exact density?

No. Match their topical coverage (the related terms they include), not their percentages. Chasing someone else's number is cargo-cult SEO.

Honest limits

Keyword density is not a Google ranking factor — this tool is a stuffing detector and topical-coverage mirror, not a ranking dial.

How to use the Keyword Density Checker

Paste text for instant analysis, or switch to Analyze a URL to check a live page.
Results show the top 1-, 2- and 3-word phrases with counts and percentages.
Use it as a stuffing guardrail — if one phrase dominates the table, rewrite for variety.

Examples

Example

Paste a 500-word article → the 1-word table shows each term's count and share of total words, e.g. "optimization" — 14 (2.1%). Flags labeled "possible stuffing" are our heuristic, not Google's verdict.

What this tool doesn't do

Keyword density is not a ranking factor (per Google). This tool is a stuffing guardrail, not an optimization target — there is no "ideal" percentage to aim for.
Stuffing flags are our heuristic, based on unusually high repetition — not a penalty detector.
URL mode analyzes the text our fetcher can see; JavaScript-rendered content may be missed.
