Keyword Density Checker
A keyword density checker measures keyword density, keyword frequency, and total word count so you can see how terms repeat. It calculates keyword density percentage using the keyword density formula (keyword occurrences / total words) × 100, then lists results as a frequency count and a percentage.
Keyword Density and Keyword Frequency Results
This tool reports keyword density and keyword frequency so you can scan repetition quickly. The total word count helps you understand why a term’s percentage changes as text gets longer. You will see keyword density percentage for each term, along with the frequency count. This makes it easier to spot repeated wording without guessing.
Check by Paste Text
You can check use paste text for fast checks. If you are still writing, custom text and draft content check help you test changes before publishing. For research, competitor page analysis helps you compare patterns across pages.
One Word Keywords and Phrase Analysis
The tool breaks results into one-word keywords and longer phrases to reflect how people actually search. It lists two-word phrases, three-word phrases, and four-word phrases, which matter more than single words. Each phrase includes a density percentage, which helps you judge repetition at a glance. This is useful when a phrase appears naturally but starts repeating too often.
Linked Words vs Non Linked Words
This tool can separate linked words from non-linked words so you see what comes from link text versus regular writing. It also helps compare on-page body text and heading text so you can spot repetition in headings. This view is useful when density looks high, but the extra repetition comes from menus, footers, or repeated anchors.
Keyword Stuffing and Over Optimization Signals
High keyword density alone does not prove a problem, but patterns can lead to keyword stuffing and over-optimization. When repetition grows, readability drops and user intent gets ignored. A safer approach uses semantic keywords, synonyms, related keyphrases, and natural word forms that fit context relevance. This keeps writing clear while still matching how people search.
What is Ideal Keyword Density?
Many people search for an ideal keyword density, but there is no universal number. Some guides mention 1–2% or below 3%, but results are always topic-dependent. Focus on whether the text reads naturally and matches user intent instead of chasing a fixed percentage. Use the checker to spot repetition, then rewrite for clarity and flow.
