Keyword density is the percentage of times a word or phrase appears in your text relative to the total word count. For example, if "SEO" appears 5 times in a 500-word article, its density is 1%.
Most SEO experts recommend a primary keyword density of 1-3%. Going above 3% may be seen as keyword stuffing by search engines, which can hurt rankings.
Stop words are common words like "the", "is", "at", "and" that search engines typically ignore. Filtering them out reveals the meaningful keywords in your text.
Multi-word phrases (n-grams) help identify long-tail keywords and topics in your content. For example, "content marketing" as a 2-word phrase is more specific than "content" alone.
