Example
A 1,000-word article mentioning 'Webflow agency' 3 times has a 0.3% keyword density — natural and within SEO best practice.
Google's John Mueller has publicly stated that keyword density is not a ranking factor Google uses — confirming that natural language and topical depth are what matter, not keyword repetition percentage.
What it applies to
All written content on a website — blog posts, service pages, landing pages. The concept is relevant primarily to avoid the mistake of either keyword stuffing or keyword avoidance.
The modern approach to keywords in content
- Use the target keyword naturally in the H1, the URL slug, the meta title, the first paragraph, and at least one H2. Beyond this, write for the reader — not for keyword frequency.
- Use semantic variants and related terms throughout — synonyms, related concepts, and the vocabulary your ICP uses when discussing the topic. Google's NLP models understand synonym relationships.
- Answer the full scope of the search intent — a comprehensive page that genuinely addresses everything a searcher wants to know will naturally include the target keyword and its variants at appropriate frequencies.
- Use tools like Clearscope, Surfer SEO, or Ahrefs' Content Grader to identify the related terms and concepts that top-ranking pages for your keyword include — then cover those topics in your content.
What to avoid
- Forcing the exact keyword into every paragraph — it reads unnaturally and modern algorithms detect it.
- Repeating the keyword in the alt text of every image on the page.
- Invisible text or hidden keyword lists — these are black-hat tactics that trigger manual penalties.
