How it works

1

Paste text or enter a URL

Add your draft content or the URL of a live page you want to analyze.

2

Add your target keyword (optional)

Enter the keyword you're targeting to get a specific verdict on whether you're using it too much or too little.

3

Review density and verdict

See every keyword's density percentage, with a highlighted verdict on your target keyword if you added one.

Analyze text or live pages

Check keyword density for draft content you paste in, or pull live HTML from any URL to see how a published page performs.

Target keyword verdict

Add your target keyword to get a plain-English verdict: is it overused, underused, or just right? No math required.

Full keyword breakdown

See every keyword and phrase extracted from your content, sorted by density percentage, so you know exactly what stands out.

No signup for 3 daily checks

Run the tool up to three times a day without creating an account. No email, no credit card.

Works on any content length

Check short landing pages or long blog posts. The tool adapts to your content and shows density as a clean percentage.

More checks in your workspace

A Letaido account lifts the daily limit, saves every result, and lets you compare keyword density across a set of pages rather than one at a time.

How to get the most out of the keyword density checker

Keyword density tells you how often a word or phrase appears in your content as a percentage of total words, and this tool makes it easy to spot when you're overdoing it or missing opportunities.

Use the target keyword field to get a verdict, not just numbers

If you enter a target keyword, the tool highlights it in the results and gives you a clear verdict: overused, underused, or balanced. This saves you from hunting through a long list of percentages.

For example, if you're writing a landing page for 'email marketing software' and the tool says it's overused at 4.2%, you know to cut a few mentions. If it's at 0.5% and marked underused, you know to weave it in more naturally.

Check live competitor pages to benchmark density

Paste a competitor's URL to see how often they use their target keyword. If a page ranking above you uses a keyword at 1.8% and you're at 0.3%, that gap might explain part of the difference.

This isn't about copying their exact density, but it gives you a reference point. If three top-ranking pages all sit between 1.5% and 2.5% and you're at 5%, you're probably overdoing it.

Review the full keyword list to catch unintended repetition

Even if your target keyword density looks fine, the full breakdown can reveal other words you're overusing without realizing it. Words like 'solution', 'platform', or 'innovative' can pile up and make your writing feel repetitive.

Scan the list for any word above 2% that isn't your target keyword. If 'our' or 'we' is at 3%, your copy might be too self-focused. If 'best' appears 20 times in a 500-word page, you're leaning too hard on hype.

Check a whole content set, not one page at a time

The free tool gives you three checks a day with no signup, which is enough to sanity check a draft before it goes live.

Inside a Letaido workspace that limit lifts and your results are saved, so you can run density across a batch of pages, compare them against each other, and spot the ones drifting into over-optimization. Because it sits beside your keyword research and content tools, the terms you are targeting and the pages you are checking live in the same place.

Frequently asked

What keyword density percentage should I aim for? +

There's no magic number, but 1% to 2.5% is a common range for a target keyword. Much higher and you risk keyword stuffing. Much lower and search engines might not see the page as relevant. The tool gives you a verdict to guide you.

Can I check keyword density for a live page I don't own? +

Yes. Enter any public URL and the tool will fetch the page and analyze it. This works for competitor pages, reference articles, or any published content you want to benchmark.

Does this tool check for keyword variations or just exact matches? +

The tool counts exact word matches. If you target 'email marketing' it will count 'email marketing' but not 'email marketing software' as a separate phrase. Each phrase is listed individually.

What does the verdict mean when I add a target keyword? +

The verdict tells you if your target keyword appears too often (overused), too little (underused), or at a reasonable frequency (balanced). It's based on typical density ranges, not a strict formula.

Why does the tool show density for words like 'the' or 'and'? +

The tool lists every word extracted from your content. Common words like 'the' or 'and' will always have high density, but they're not useful for SEO. Focus on nouns, verbs, and your target keywords.

Can I save my keyword density results? +

Not in the free tool. If you add this tool to a Letaido workspace, you can save every check, compare results over time, and export data to use in reports or other tools.
