Keyword density for SEO

Repeating the right keyword in the right dose is part of optimising a text for search engines. Too little and the topic gets diluted. Too much and it sounds artificial, or reads as spam to Google. The tool counts how often each word appears and shows its density as a percentage.

Besides single words, it also looks at bigrams (word pairs), which are often the most valuable search phrases. With that overview in front of you, you check whether the main term shows up enough, notice which words repeat too much, and tune the text toward a more balanced on-page SEO.

The analysis runs entirely in the browser, without sending the text anywhere. Paste the content and the count and density appear right there, ready to guide your article's revision.

Frequently asked questions

Does the tool count two-word phrases?

No. Counting happens word by word, and the table lists the 20 most frequent single terms. A phrase like digital marketing never shows up as one row: it shows up as digital and marketing, on separate rows. To gauge a multi-word phrase, look at how often each of its words appears and compare, or run a search over the draft in your own text editor.

How is the density percentage calculated?

Occurrences of the word divided by the total word count of the text, to two decimal places. The confusing bit is the denominator: it counts everything, including the words the table throws away. One- and two-letter words stay out of the list, as does a fixed set of articles, prepositions and connectors in Portuguese and English, yet all of them still weigh in the total shown at the bottom. That is why the table percentages never add up to 100%.

Do accents and capitals change the count?

Capitals no, accents yes. The whole text is lowercased before counting, so SEO and seo land on the same row. Accented spellings are a different story: two forms of the same word count as separate terms, because the comparison runs character by character with no accent folding. Hyphenated words get split as well: step-by-step becomes three pieces, and the two-letter by in the middle drops out.
