How to interpret this report
Keyword frequency can help you spot repetition, gaps, and unnatural wording. It is not a ranking formula and there is no universal target percentage.
- Repeated words:Decide whether repetition helps the reader or makes the copy feel forced.
- Missing topic language:If an important phrase barely appears, check whether the page explains that topic clearly.
- Phrase patterns: 2-word and 3-word phrases show repeated labels, themes, and wording habits.
- Reader-first editing:Use the data to improve clarity, headings, and natural wording.
Frequently Asked Questions
What is keyword density?
Keyword density is the percentage of times a word or phrase appears relative to the total word count. It helps you spot repetition, missing topic language, or awkward wording — not hit a ranking formula.
What is the ideal keyword density for SEO?
There is no ideal percentage. If a phrase barely appears, the page may not cover that topic clearly. If it appears constantly, the copy may feel repetitive. Write for readers first and use this report as an editing aid.
How do I avoid forced repetition?
Forced repetition means using the same words in a way that sounds unnatural or unhelpful. Avoid it by reading the copy aloud, removing needless repetition, and using natural language that answers the reader's question.
Does Google reward exact keyword percentages?
No reliable SEO rule says a page needs a specific percentage. Modern search systems evaluate meaning, usefulness, context, and many other signals. Clear wording and natural topic coverage matter more than hitting a ratio.
Should I review single words or phrases?
Review both. Single-word counts reveal obvious repetition, while 2-word and 3-word phrases show repeated ideas, labels, and natural wording patterns. Use those patterns to make the page clearer.
What is the difference between keyword frequency and keyword density?
Keyword frequency is simply the raw count of how many times a keyword appears in your content. Keyword density is the frequency divided by the total word count, expressed as a percentage. Density is more useful for comparison across different content lengths — a keyword appearing 10 times in a 200-word article (5% density) is very different from appearing 10 times in a 2000-word article (0.5% density).
How does stop word filtering affect my density analysis?
Stop words (like "the," "and," "for," "but," "this") are common words that carry little SEO value individually. Our analyzer filters out stop words from the single-word analysis to surface meaningful keywords. However, stop words ARE included in the n-gram (2-word and 3-word phrase) analysis because they can be part of meaningful phrases like "how to optimize" or "best for SEO."
Can I use this tool to analyze competitor content?
Yes! Paste any competitor article or webpage content into the text area, or use the "Fetch from URL" feature to pull content directly from a competitor's page. Analyze their keyword usage patterns, identify their primary and secondary keywords, and see which 2-word and 3-word phrases they're targeting. This is a great way to reverse-engineer content strategies.
How do I use phrase analysis?
Phrase analysis helps you see repeated wording patterns. If the same phrase appears often, decide whether it helps the reader, should be varied, or belongs in a heading because it describes a real section of the page.
