Check word and phrase frequency in your content
Paste your text and see which words and phrases repeat, how often, and as what share of the total. One-word, two-word and three-word patterns are counted separately, because a phrase that appears eight times tells you far more than a single word that does.
One thing to be clear about first: keyword density is not a ranking factor, and it has not been one for a long time.
What density is actually useful for
There is no target percentage. Google has not used keyword density as a ranking signal in well over a decade, and any guide quoting an ideal "1–2%" is repeating advice that expired around 2011. Writing to hit a number produces worse copy, and modern systems read meaning rather than counting occurrences.
What the numbers are genuinely good for is diagnosis. Two things show up clearly in a density report:
- Accidental repetition. If one phrase appears thirty times in 800 words, the writing has a tic. That is an editing problem, and it reads badly whether or not a search engine cares.
- A missing topic. If you have written 2,000 words about AI detectors and the phrase "false positive" appears zero times, you have a coverage gap. That is the more valuable finding of the two.
Why phrases beat single words
Single-word counts are dominated by filler. In almost any English document the top entries will be "the", "and" and "to", which tells you nothing at all.
Two- and three-word patterns are where the signal is. They show the phrases you actually lean on, and they map much more closely to what people type into a search box — nobody searches for "detector" on its own.
Using it on a competitor page
Paste the main text of a page that outranks you and read the phrase list. You are not looking for a density figure to copy — you are looking for concepts they cover that you do not.
A page ranking for "ai detector" that repeatedly mentions false positives, Turnitin and perplexity is telling you what the query is understood to be about. That list is a content brief, and it is more useful than any percentage on the page.
