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.
