Keyword density (कीवर्ड घनत्व या कीवर्ड डेंसिटी) is the percentage ratio of how many times your target keyword appears divided by the total number of words on a page. If you write a 500-word article and use your main keyword 5 times, your density is 1%. The formula is simple: (number of keyword appearances ÷ total words) × 100. Back in the early 2000s, SEO practitioners obsessed over hitting specific density targets like 2-3%, believing Google rewarded exact percentages. That era ended around 2011-2012 when Google's algorithms became sophisticated enough to understand semantic relationships and penalize keyword stuffing. Today, there's no magic number. We see pages ranking at 0.5% density and others at 2.5%, depending on content length, topic complexity, and how naturally the keyword fits. At Ottawa SEO, we don't calculate density anymore. Instead, we focus on natural language and topic coverage. If you're writing about "Ottawa web design," you'll naturally mention it in your title, first paragraph, a few subheadings, and conclusion without forced repetition. The keyword should appear where it makes logical sense to a reader, not to hit an arbitrary percentage. What matters more is semantic completeness: covering related terms (LSI keywords or entities) that Google expects for your topic. For a Hindi-language site targeting Indian markets, the same principles apply—use your main keyword naturally while covering the topic thoroughly with related Hindi terms your audience actually searches. Watch out for over-optimization. If you're calculating density and artificially inserting keywords to reach a target, you're probably hurting readability and triggering Google's spam filters. Focus on writing for humans first, ensuring your primary keyword appears in strategic locations (title tag, H1, first 100 words, URL), then let natural usage dictate the rest.
