Keyword Density: What It Is and How to Check It (Free Tool)

On this page

“What’s your keyword density?” If you write content for the web, you’ve heard the question — and gotten ten different answers about the “right” number. Some say 1%. Some say 2%. Some say it doesn’t matter at all anymore.

Here’s the honest version: keyword density is a useful diagnostic, not a ranking formula. It tells you whether your target phrase appears naturally or whether you’ve stuffed it (or forgotten it). Here’s what it is, how to calculate it, what range is safe, and how to check yours in seconds.

What is keyword density? (With the actual formula)

Keyword density is simply the percentage of times a keyword or phrase appears in your text, relative to the total word count:

Keyword density = (number of times the keyword appears ÷ total words) × 100

Example: your target phrase “best budget laptop” appears 12 times in a 1,000-word article.

12 ÷ 1,000 × 100 = 1.2% density

That’s it. No mystery. The number just describes how prominent your phrase is in the text.

Why does anyone care? Because the extremes are both bad. Near-zero density can mean Google isn’t sure what the page is about. Very high density usually means the text reads like it was written for a robot — which, historically, is exactly what it was. Density is a quick sanity check between those extremes.

How to check your keyword density in 3 steps (free)

Counting by hand is miserable — especially for two- and three-word phrases. DollarWise’s free keyword density checker does it instantly:

Open the keyword density checker and paste your article text (or type it directly).
Enter your target keyword or phrase — the tool counts exact matches, including multi-word phrases.
Read your results: overall density percentage, total occurrences, and a frequency breakdown of the top single words, two-word phrases, and three-word phrases in your text.

The phrase breakdown is the genuinely useful part. It often surfaces accidental repetition you didn’t notice — like using “in today’s fast-paced world” four times — and phrases you should be repeating more for topical relevance.

What is a good keyword density?

Here’s the range most SEO professionals work with, and the reasoning behind it:

The safe zone: roughly 1–2%

For your primary keyword, 1–2% is the conventional comfort zone — prominent enough that the topic is unmistakable, low enough that the text reads naturally. A 1,500-word article at 1.5% mentions the phrase about 22 times, which feels natural when the article is genuinely about that topic.

Google has no official target

This is important: Google has never published an “ideal” density, and its representatives have repeatedly said to write naturally. Modern Google understands topics and synonyms, not just exact-match counts. Density is a guardrail, not a goal — nobody ever ranked #1 because they hit exactly 1.73%.

Above 3%: the stuffing zone

If your primary phrase is pushing past 3%, read the text out loud. If it sounds repetitive to you, it reads as spammy to Google too — and keyword stuffing is explicitly against Google’s spam policies. Pages can and do lose rankings over it.

Don’t forget secondary phrases

Your article should also naturally include related terms (Google calls these topical signals): a post about “best budget laptops” should mention “battery life,” “Chromebook,” “under $500,” and so on. The checker’s phrase-frequency table shows whether your supporting vocabulary is present or whether you’ve written 1,500 words saying the same thing one way.

How to fix density that’s too high or too low

If density is too high (over ~3%)

Use pronouns and synonyms: after introducing “best budget laptop,” switch to “it,” “this machine,” “the laptop,” or “a budget option.” Readers prefer variety anyway.
Cut filler repetitions: search your draft for the phrase and delete the instances that add nothing — intros and conclusions are the usual offenders.
Restructure, don’t just delete: sometimes high density means the article is thin and repeating itself. Adding genuinely new sections (a comparison table, an FAQ) dilutes density while improving the article.

If density is too low (under ~0.5%)

Check your headings: your H2s should include the keyword or close variants at least once or twice. Headings carry extra topical weight.
Strengthen the intro and conclusion: the first 100 words should establish the topic clearly — that’s good writing and good SEO.
Add the missing sections: low density often means the article doesn’t cover the topic thoroughly. A “how to choose” or “things to avoid” section naturally adds relevant mentions.

The 30-second rule of thumb

Write the article for a human first. Then check the density. If it’s between 0.5% and 2.5% and the text reads smoothly, you’re done — ship it. Density tweaking beyond that point has never been what separates ranking content from non-ranking content. Depth, clarity, and actually answering the question do that.

Once your on-page wording is in shape, make sure your page’s behind-the-scenes tags are too — generate your meta tags (title, description, and social previews) in about two minutes.
