About this tool

Keyword density is the share a word or phrase occupies among all words. There is no magic target, but natural writing usually keeps the top keyword under 2–3%; beyond that reads as stuffing. This tool ranks 1-word and 2-word phrases so you can check your main keyword's prominence and discover accidental repetition.

The Keyword Density Formula (With a Worked Example)

Keyword density is the percentage a phrase occupies in your text. The formula is simple: (number of keyword repetitions ÷ total words) × 100. If your 800-word article mentions "keyword density checker" 6 times, the density is 6 ÷ 800 × 100 = 0.75%. Counting phrases matters too: a two-word phrase used 6 times contributes 12 keyword instances, but SEO tools conventionally count phrase occurrences, not individual words.

Worked example: a 1,200-word blog post targets three terms. "Free keyword tool" appears 8 times (0.67%), "keyword density" appears 14 times (1.17%), and the brand name appears 4 times (0.33%). All three sit in the healthy 0.5–1.5% band, which is exactly what you want. Paste your draft into the checker above and verify each phrase separately — that is how professionals audit before publishing.

What Is the Ideal Keyword Density in 2026?

There is no official Google target — modern ranking systems understand synonyms, context and topic coverage rather than counting exact repetitions. That said, working editors still use practical bands to keep writing natural. For most content types, staying between 0.5% and 1.5% for a primary phrase keeps the page on-topic without tripping spam heuristics. Long guides (2,500+ words) tolerate the lower end because absolute mentions still add up.

• Product and tool pages: 0.5–1.0% — the page name naturally repeats in UI text, headings and support copy.
• Blog guides: 0.8–1.5% — explanatory writing repeats the core phrase while defining related subtopics.
• FAQ and help sections: variable — answer the question naturally; forcing density here reads badly.
• Localised variants: treat each city or brand variant as its own phrase and check it separately.

If a phrase scores above ~2%, do not delete mentions blindly — first swap exact repeats for synonyms and pronouns, then re-check. Readability improves and density falls together, which is precisely the outcome search quality guidelines reward.

Keyword Stuffing: The Signs Reviewers (and Algorithms) Look For

Stuffing is not just a high percentage — it is repetition that a human editor would flag as unnatural. Typical tells include lists of city names stitched into a sentence, the same exact phrase opening five consecutive paragraphs, hidden text repeating terms in white-on-white blocks, and footer link farms pointing at one URL with identical anchors. Each of these patterns has appeared in Google's spam policies for years, and each is detectable with a simple density scan plus a manual read.

A healthy page passes three checks: the phrase appears in the title and one H2, density sits in the healthy band, and every mention earns its place by adding information. Run the checker above, sort phrases by density, and read any phrase above 2% in context. If removing a mention loses no meaning, it was stuffing; if it breaks the sentence, it was earning its place.
