Focus on writing for human readers first; the density should feel natural.
Exclude "stop words" (the, and, of) to get a clearer picture of your meaningful content.
Keyword density is the percentage of times a keyword or phrase appears on a webpage compared to the total number of words on that page.
While there is no "magic number," most SEO professionals recommend a density between 1% and 3% to stay competitive without over-optimizing.
Keyword stuffing is the practice of loading a webpage with keywords in an attempt to manipulate search rankings. This often results in a poor user experience and can lead to penalties.
Stop words are common words like "the," "is," and "at" that search engines often ignore. Excluding these helps you focus on the meaningful keywords in your content.
The tool looks for contiguous sequences of words (2-word and 3-word phrases) to help you identify the most frequent compound terms in your writing.

LSI (Latent Semantic Indexing) keywords are terms that are conceptually related to your primary keyword. Using these alongside your main keyword helps search engines better understand your content's context.
Yes, our tool is free to use for both manual text entry and URL-based analysis.
No, for the best results, you should focus on the main body of your content. Our URL fetcher attempts to strip away navigation and footer elements to prioritize the actual article text.
To lower density, replace some instances of your main keyword with synonyms, pronouns, or related descriptive phrases.
