Frequently Asked Questions
What is keyword density in SEO?
Keyword density is the percentage of times a specific word or phrase appears in your content relative to the total word count. It is calculated as (keyword count ÷ total words) × 100. For example, if a 1,000-word article uses the word "SEO" 10 times, the keyword density is 1%. It helps you understand whether a keyword is used at an appropriate frequency — too rarely and Google may not recognise the topic clearly; too often and the content risks looking spammy.
What is the ideal keyword density for SEO?
Most SEO practitioners aim for a natural frequency of 0.5% to 2% for the primary keyword. Google's algorithms evaluate topical relevance through semantic context, not keyword repetition alone. Focus on writing naturally and covering the topic comprehensively. Using related terms, synonyms, and contextually relevant phrases — rather than repeating one exact keyword — tends to produce better rankings and a better reading experience for your audience.
What is keyword stuffing and how does Google penalize it?
Keyword stuffing means artificially inflating the frequency of a target keyword in page content to manipulate search rankings. It includes unnaturally repeating keywords in body text, hiding keywords using CSS, and filling meta tags with repeated phrases. Google's spam policies explicitly target keyword stuffing and may demote or remove pages from search results. Since the Panda update, Google measures content quality holistically — naturally written content that provides genuine value consistently outranks keyword-stuffed pages.
