Word itself doesn't include a keyword density tool, so you need to calculate it manually or use online alternatives. Open your document, press Ctrl+F to open the Find dialog, type your target keyword, and Word will show you how many instances it found. Then check your total word count in the bottom status bar or the Review tab. Divide keyword mentions by total words, multiply by 100, and you have your density percentage. For a 1,000-word article with 15 mentions of "Ottawa web design", that's 1.5% density. Most SEO practitioners aim for 0.5–2.5% for primary keywords, though keyword density as a standalone metric matters far less than it did in 2010. Google cares more about topical relevance and natural language than hitting a specific percentage. If you're checking density regularly, copying your content into a free online tool like SEOReviewTools or SmallSEOTools is faster than manual math in Word. These tools also show density for two-word and three-word phrases, which is useful since most target keywords are longer than single words. Some also flag over-optimization, though take those warnings with context since industry writing naturally repeats terms more than general content. At Ottawa SEO, we rarely obsess over exact density numbers when writing or auditing content. We focus on whether the keyword appears in the title, first 100 words, at least one H2, and naturally throughout the body. If you're writing for humans first and covering the topic thoroughly, density usually lands in a reasonable range without forcing it. Problems arise when writers either stuff keywords to hit 3–4% or avoid them entirely out of over-optimization fear, landing under 0.3% and losing topical clarity. Word is fine for basic counting, but if you're doing this more than occasionally, a dedicated SEO plugin in Google Docs or a content optimization tool like Clearscope or Surfer makes more sense than toggling between Find dialogs and calculators.
