Why This Matters for SEO

Word and phrase frequency is a useful editorial diagnostic, not a ranking target. It can reveal accidental repetition, boilerplate, or terminology that is missing from an otherwise complete explanation. Use the results to improve natural language and topic coverage rather than aiming for a percentage.

Frequently Asked Questions

What is the ideal keyword density?+
There is no universal ideal percentage. Cover the topic thoroughly in natural language and use the words readers expect where they genuinely fit.
What are n-grams?+
N-grams are sequences of N words. Unigrams are single words, bigrams are two-word phrases, and trigrams are three-word phrases. Analyzing them reveals which phrases dominate your content.
Can keyword stuffing hurt rankings?+
Yes. Repeating words or numbers unnaturally in an attempt to manipulate rankings can violate Google's spam policies. Write for readers and use this report as an editorial sanity check.
