Google Docs doesn't include a native keyword density feature, so you need external tools. The fastest method is copying your content from Docs and pasting it into a free web-based analyzer like SEOReviewTools, KeywordDensityChecker.com, or Copywritely. These show you percentage breakdowns for single keywords and two-word or three-word phrases within seconds. If you work in Docs frequently, install a Chrome extension like SEO Minion or SEOquake. These let you highlight text in any browser tab and run quick density checks without leaving your document. The trade-off is they're less detailed than dedicated tools, but they save repetitive copy-paste cycles when you're drafting multiple pieces. Keyword density itself is largely a legacy metric. Google hasn't used strict density thresholds since the early 2000s, and chasing a specific percentage often leads to awkward, repetitive writing. What matters more is topical coverage and natural language. If a target keyword appears 8 times in 500 words versus 12 times, the ranking difference is usually negligible compared to whether you've covered related entities, answered the search intent, and matched the semantic context Google expects. At Ottawa SEO, we check density as a sanity test, not a target. If a focus keyword shows up less than twice in 800 words, we probably under-optimized. If it's above 4–5%, we likely over-optimized and the copy reads like spam. We treat density as a diagnostic for content that feels off, then rely on manual editing and tools like Clearscope or SurferSEO to confirm we've hit the topical depth competitors rank for. For most commercial pages, aim for natural repetition. Your primary keyword might land around 1–2% density, with variations and semantically related terms filling another 2–3%. That usually covers intent without triggering over-optimization penalties or annoying human readers, which is the actual goal.
