Common use cases

Blog and SEO content audits

Paste a finished article to confirm your primary keyword appears naturally and that secondary phrases show up in the right places without reading as spam.

Landing and product page copy

Check whether benefit phrases and product names dominate the page, then rebalance weak sections before launch.

Content briefs and editor feedback

Copy the density table into a brief or review doc so writers know which terms are overused or missing.

Competitive phrase research (manual)

Paste a competitor's public page (one at a time) to see which multi-word phrases they emphasize - then write original copy that covers the same topics.

Examples

• Audit a blog draft for stuffing: Paste a finished post and check whether your primary keyword sits around a natural 1-2% density. Spikes far above that often read as stuffing.
• Find missing focus phrases: Switch to 2-word or 3-word mode. If your target phrase never appears (or appears once in 2,000 words), add it naturally in the intro, an H2, and the conclusion.
• Compare product page copy: Paste competing product descriptions side by side (one at a time) and note which benefit phrases dominate - then balance your own page without copying.

Pro tips

• Aim for natural language first. If a draft sounds repetitive, density is too high even if the percentage looks "in range."
• Use 2- and 3-word mode for real SEO phrases; 1-word mode is noisy because of common stop words like "the" and "and."
• Pair with Word Counter for length targets and Meta Description Checker for the SERP snippet after the body is solid.
• Put the focus phrase in the title, early intro, an H2, and the conclusion - density alone is not enough.
• After locking the URL slug with Slug Generator, re-check density so the permalink keyword still appears in the body.

Frequently asked questions

What is keyword density?

Keyword density is how often a word or phrase appears relative to the total word count, usually shown as a percentage. For example, a term used 10 times in a 1,000-word article has 1% density. It is a quick health check for focus and overuse - not a ranking formula by itself.

What is a good keyword density?

There is no official Google target. Most editors aim for a natural feel - often roughly 0.5-2% for a primary keyword in longer articles - and prioritize clear writing over hitting an exact number. If the page sounds repetitive, density is too high regardless of the percentage.

Does keyword density affect SEO rankings?

Modern search engines look at relevance, intent, and quality far more than raw density. Extreme stuffing can hurt readability and trust. Use this tool to stay on-topic and avoid overuse, then focus on helpful structure, unique value, and matching search intent.

How are words and phrases counted?

Text is lowercased and punctuation is stripped, then split on whitespace. Density is (occurrences ÷ total words) × 100. In 2-word or 3-word mode, overlapping consecutive phrases are counted the same way against the same total word count.

Should I filter common stop words?

This checker shows all tokens so you can see the full picture (including words like "the" or "and"). When optimizing, focus on meaningful keywords and phrases - not stop words - and use 2- or 3-word mode to surface real topics.

Is my content uploaded anywhere?

No. Analysis runs entirely in your browser. Drafts and confidential copy never leave your device, so it is safe for unpublished posts and client work.
