Open SEO Content Score Checker →Keyword density is how often a term appears as a share of the total word count. Checking it catches two problems: a target phrase that barely appears, meaning the page may not read as being about that topic, and a phrase repeated so often it looks stuffed. Seeing the top words and their percentages side by side shows where your copy actually puts its emphasis, which is often not where you assumed.
There is no magic percentage to hit; modern search ranking is about relevance and quality, not a keyword quota. Use the checker to sanity-check that your main topic reads naturally and that you have not accidentally over-repeated a phrase. A companion SEO content word counter reports the overall length alongside the density, since word count and keyword balance both matter for a page. Both run in your browser with nothing uploaded.
There is no fixed target. Use the checker to confirm your main topic appears naturally and is not stuffed, rather than hitting a specific percentage.
