How to Check Keyword Density Using a Word Counter

Keyword density is the percentage of words in a piece of content that match a particular keyword or phrase. If a 1,000-word article uses "standing desk" 12 times, the phrase covers 24 of those words, so its density is about 2.4%. Measuring it takes less than a minute with a word counter that has a density panel.

Step-by-step: measure density in under a minute

1. Paste your finished draft into the word counter.
2. Switch on Ignore common words so filler such as "the", "and" and "to" disappears from the list.
3. Look at the 1 word tab to see your most repeated single terms.
4. Switch to the 2 words and 3 words tabs. Most real search queries are phrases, so this is where your focus keyword usually shows up.
5. Note the count and percentage beside your target phrase.

How to read the results

There is no magic percentage that guarantees rankings, and Google has said repeatedly that it does not use a fixed density target. Treat the numbers as a diagnostic:

• Your keyword is missing from the top phrases. The page may not clearly signal its topic. Add the phrase to the introduction, one subheading and the conclusion where it reads naturally.
• One phrase towers over everything else. If your keyword appears far more often than any other meaningful phrase, the copy may read as repetitive. Replace some instances with synonyms or pronouns.
• Unexpected words dominate. A brand name or a tangent may be pulling attention away from the topic. Tighten that section.

Look at the whole vocabulary, not one keyword

Search engines understand topics through related words. An article about standing desks naturally mentions height, posture, ergonomics, motors and desk frames. Scan the density list for these supporting terms. If they are absent, the article may be thin on detail, and adding a section that answers a real reader question usually fixes both the density and the usefulness.

Tip: Check density after editing, not while drafting. Writing for a number first produces stiff copy; writing for the reader first and checking afterwards produces copy that ranks and converts.

Frequently asked questions

What is a good keyword density?

There is no official number. Many SEO writers find that a main keyword naturally lands somewhere around 1 to 2 percent of the text, but Google does not reward a target percentage. A good keyword density is one where the phrase appears in the important places (title, introduction, a heading) and the rest of the copy still reads naturally.

What is the keyword density formula?

The keyword density formula is: (number of times the keyword appears x number of words in the keyword) / total words x 100. For a two-word phrase used 10 times in a 1,000-word article, that is 10 x 2 / 1,000 x 100 = 2 percent. A word counter with keyword density does this maths for you.

How to calculate keyword density by hand?

To calculate keyword density by hand, count how often the phrase appears, multiply by its number of words, divide by the article's total word count and multiply by 100. It is quicker to paste the text into a word count tool that lists word frequency and percentages automatically.
