Frequently Asked Questions About Keyword Density Analyzer
What is keyword density?
Keyword density is the percentage of times a word or phrase appears in your text relative to total word count. For example, if "SEO" appears 5 times in a 200-word article, its density is 2.5%. The ideal keyword density for SEO is typically 1-3%.
What is the ideal keyword density?
Most SEO experts recommend a keyword density of 1-3% for primary keywords. Going above 5% may trigger keyword stuffing penalties from search engines. Focus on natural, readable content.
What are two-word phrases (bigrams)?
Two-word phrases are pairs of consecutive words, also called bigrams. For example, "search engine", "keyword density", and "content marketing" are two-word phrases. Analyzing these gives you insight into phrase-level keyword usage.
