Frequently asked questions

What is keyword density?

Keyword density is the percentage of times a keyword appears relative to total word count. It helps you gauge how naturally a keyword is used in your content.

What is the ideal keyword density?

Most SEO experts recommend 1-3% for your primary keyword. Going above 3% risks being flagged for keyword stuffing.

Does keyword density still matter for SEO?

While Google uses semantic understanding, keyword density remains a useful guideline. Natural keyword usage signals topic relevance to search engines.

What are n-grams?

N-grams are contiguous sequences of words. 1-grams are single words, 2-grams are two-word phrases, and 3-grams are three-word phrases.

Why are stop words filtered?

Common words like 'the', 'and', 'is' are filtered to surface meaningful keywords. This gives you a clearer picture of your content's topical focus.

Where should I paste my content?

Paste the main body text of your page. Leave out menus and footers so the results reflect what the page is really about.

What is keyword stuffing?

Repeating a keyword so often that the text reads unnaturally. Google can demote stuffed pages, so write for readers first.

Should I use synonyms?

Yes. Related words and phrases help Google understand the topic and make the text read naturally.

Why check two and three word phrases?

Most searches are several words long. Phrase density shows whether your key phrases appear, not just single words.

Is my text stored?

No. The analysis runs in your browser and your text is not sent to our servers.
