Frequently Asked Questions
What is keyword density?
Keyword density is the percentage of times a keyword appears in your content relative to the total word count. For example, if your keyword appears 10 times in a 1,000-word article, the density is 1%. It helps search engines understand what your content is about.
What is the ideal keyword density for SEO?
The ideal primary keyword density is 0.5-2%. Above 2% is acceptable but risky. Anything above 3% may be flagged as keyword stuffing by Google, which can hurt your rankings. Focus on natural writing with semantic variations instead of repeating the same phrase.
What is keyword stuffing and why is it bad?
Keyword stuffing is the practice of unnaturally repeating keywords to manipulate search rankings. Google's algorithms detect this and can penalize your page by lowering its ranking or removing it from results entirely. Modern SEO rewards natural, helpful content over keyword repetition.
What are bigrams and trigrams?
Bigrams are 2-word phrases (e.g., 'content marketing') and trigrams are 3-word phrases (e.g., 'search engine optimization'). Analyzing these multi-word phrases helps you identify your content's topical focus and find long-tail keyword opportunities that single-word analysis misses.
How often should I check keyword density?
Check keyword density before publishing any new content and during content audits. It's especially important when targeting competitive keywords where over-optimization could cost you rankings. Use this tool alongside the AI Content Scorer for a complete optimization check.
