Why Use a Keyword Density Checker?
A keyword density checker helps you review how often a target topic appears in your content. This is useful for blog posts, service pages, category pages, ecommerce descriptions, and SEO landing pages where you want clear topical coverage without repeating the same terms too aggressively.
SwiftTools goes beyond single-word counts. It also highlights 2-word phrases and 3-word phrases, which makes it easier to spot whether your copy leans too heavily on the same wording or misses useful supporting variations.
Example Use Cases

Keyword Density Checker FAQ
What is keyword density?
Keyword density is the percentage of times a word or phrase appears in a piece of content relative to the total word count. It is useful as a diagnostic metric, but it should not be forced unnaturally.
Does keyword density still matter for SEO?
It matters as a quality check, not as a hard target. Use it to identify overuse, underuse, and missing phrase variations while writing naturally for people first.
Can I check multi-word phrases?
Yes. SwiftTools analyzes single keywords, 2-word phrases, and 3-word phrases, and it also lets you enter a target phrase to measure exact usage.
Is my content private?
Yes. The keyword density checker runs in your browser, so the text you paste stays on your device and is not uploaded to a server.
