Keyword Density Checker: Measure Terms on a Page — Guide
keyword density checker: Check keyword density by counting terms and variants, reviewing page context, and avoiding repetitive writing that harms readability.
Keyword density is the share of a text occupied by a term or phrase. It can help you spot accidental repetition, but there is no universal percentage that guarantees a page will rank. Search systems consider meaning, usefulness, and context rather than rewarding a single formula. Use a density checker as an editing aid: inspect exact phrases and related language, then read the page aloud to make sure it serves people instead of repeating a keyword unnaturally.
Define the text and phrase you are counting
Decide whether the count includes headings, navigation, captions, and metadata or only the main article. Normalize capitalization and whitespace, but be careful with punctuation and word boundaries. For a phrase, count complete phrase matches rather than matching fragments inside longer words. A simple frequency percentage is often total occurrences divided by total words, multiplied by 100; tools may use different tokenization rules, so compare like with like.
Review related terms and intent
A useful page may include synonyms, examples, entities, and questions that naturally belong to the topic. Do not add unrelated variants simply to increase a score. Compare the page with the reader’s task: what information would help someone complete it accurately? Use headings to make the structure clear, then remove sentences that repeat a point without adding detail. A count can highlight a pattern, but editorial judgment determines whether that pattern improves the page.
Avoid fixed density targets
Search guidelines do not require a fixed keyword density. Repeating an exact phrase in every heading can make the article awkward and may look manipulative. Use the main phrase where it clearly describes the subject, then write naturally. Check readability, factual support, and whether the page answers a distinct query better than a generic overview. Reassess after editing because a percentage can change when the overall text length changes.
Worked example
Text words: 800
Exact phrase matches: 8
Simple frequency: 8 / 800 × 100 = 1%
Next step: review each use for clarity and relevanceWhat is a good keyword density percentage?
There is no universally recommended percentage. Use frequency to notice repetition, then prioritize accurate, useful, readable content.
