◆ The Basics

What Is Keyword Density?

Keyword density is the percentage of times a specific keyword or phrase appears in a piece of content relative to the total word count.

◆ Keyword Density Formula ◆

Keyword Density (%) = (Occurrences ÷ Total Words) × 100

In a 1,000-word article where “affiliate marketing” appears 8 times:
8 ÷ 1,000 × 100 = 0.8% keyword density

What Is the Ideal Keyword Density for SEO?

Modern SEO doesn't have a strict “ideal” density — Google's algorithms have evolved well beyond simple keyword frequency counting. However, practical guidance from SEO experts suggests:

Density Range

0%

Keyword Absent

0.1–0.5%

Very Low

May be insufficient signal

0.5–2%

✓ Optimal

Aim for this range

2–3%

Borderline

3%+

⚠ Over-Optimised

Diversify keyword variations

Rather than targeting a specific density, the modern approach is to use the primary keyword naturally where it makes semantic sense, supplement with related terms and LSI keywords, and ensure keyword usage doesn't compromise readability.

◆ Step-by-Step

How to Use the Keyword Density Checker

01

Paste Your Content or Enter a URL

Paste your full article text to analyse a piece of content.

02

Enter Your Target Keywords

Specify the keywords you want to check. You can analyse:

  • Single keywords (“affiliate marketing”)
  • Two-word phrases (“affiliate commission”)
  • Three-word phrases (“best affiliate programs”)

03

Review the Results

The tool displays keyword frequency, density percentage, top 1-word / 2-word / 3-word phrase combinations, and flags for keywords appearing to be over-optimised (>3% density).

04

Compare Against Competitors

Paste a competitor's article to see their keyword density and compare your own content strategy against the top-ranking pages for your target keyword.

◆ Semantic SEO

Beyond Keyword Density: LSI and Semantic SEO

Modern high-ranking content doesn't rely on keyword stuffing — it demonstrates topical depth through semantic coverage. The keyword density checker helps you identify whether:

01

You're covering related subtopics — through variety in top phrases

02

The article appears naturally written — even distribution of keywords

03

You're missing semantic terms — that competitors include in top-ranking articles

◆ Example LSI Terms for “Affiliate Marketing” Article

tracking links

affiliate programs

◆ By Content Format

Keyword Density for Different Content Types

📖

Long-Form Guides (2,000+ words) 0.5–1%

More room for natural variation. Primary keyword density around 0.5–1% with heavy use of LSI and related terms throughout.

⭐

Product Reviews (1,500–2,500 words) 1–2%

Product name may appear more frequently — aim for 1–2% for the product keyword. Use natural variations like “the tool,” “the platform.”

📊

Statistics Pages varied

Multiple keywords at lower individual densities. The article naturally covers many related terms from citing different data sources.

🎯

Landing Pages (300–800 words) 1.5–2.5%

Density can legitimately run higher because shorter content requires more focused language to communicate value and intent.

◆ Frequently Asked

Questions, Answered Honestly.

Google doesn't publish an exact threshold, but content with unnaturally high keyword repetition (3%+) is associated with reduced rankings. More importantly, keyword-stuffed content reads poorly — and poor user experience signals do affect rankings.

Yes. Paste the text of the top-ranking competitor for your target keyword to see how they naturally use keywords. This benchmarks your own optimisation against pages Google already rewards.

Density is frequency. Prominence refers to where in the content a keyword appears — title, first paragraph, headers. Keywords appearing early and in headers signal stronger relevance to search engines.

Yes. The tool flags keywords appearing at densities above 3% and highlights all occurrences in the text so you can review and edit them for natural variation.

Check density. Fix over-use.

Rank without risk.

Keyword stuffing is one of the fastest ways to tank an article that should rank. One paste, instant results — know your numbers before you publish.
