Online Keyword Density Checker Tool
A keyword density checker shows how many times your target keyword appears compared to your total word count. This tool will help you to avoid both keyword stuffing and under-optimised content. Going too high risks penalties for manipulative content, while going too low can make your topic unclear to search engines. This free tool from Website SEO Rankers gives you an instant, accurate reading so you can fix issues before you publish.
Good keyword usage works best alongside other checks. Once you’ve reviewed your density, use our Title and Meta Description Checker to make sure your page shows up properly in search results, and our Word and Character Counter to confirm your content’s length and reading time fit its purpose. At Website SEO Rankers, we built these tools to help business owners and content writers across the UK optimise their websites without needing paid software. Building these quick checks into your writing routine is a simple habit that can meaningfully improve how your content performs on Google over time.

Paste your content and target keyword to check how often it appears and whether the density is in a healthy range.
How keyword density works
Keyword density measures how often your target keyword appears compared to the total word count of your content. A healthy density of around 0.5 to 2.5 percent helps search engines understand your topic without your content reading as keyword stuffed. Always prioritise natural, readable writing over hitting an exact percentage.
Frequently Asked Question
What is a Good Keyword Density For SEO?
A good keyword density is generally between 0.5% and 2.5%, which keeps your content readable while still signalling your topic clearly to search engines.
Can a High Keyword Density Get my Website Penalised?
Yes, repeating a keyword too often is known as keyword stuffing, and search engines like Google can lower your rankings if your content reads as manipulative rather than natural.
What is Keyword Density and Why Does it Matter?
Keyword density is the percentage of times a keyword appears in your content compared to the total word count, and keeping it in a natural range helps search engines understand your topic without appearing spammy.
