Why is Keyword Density Important for SEO?
Keyword density represents the percentage frequency of a specific keyword or phrase relative to the total word count on a webpage. In the early days of SEO, repeating keywords frequently was enough to rank. However, modern search engine algorithms like Google Helpful Content Update prioritize natural, user-centric writing.
Recommended Density Benchmarks
- Primary Keywords: Aim for a density between 1% to 2.5%.
- Secondary & Long-Tail Phrases: Keep 2-word and 3-word phrase density around 0.5% to 1.5%.
- Keyword Stuffing Risk: Anything above 3.5% may trigger over-optimization penalties from search engines.
What are Stopwords?
Stopwords are common structural words like "the", "and", "in", and "of". Enabling stopword filtering removes these non-essential terms so you can focus on meaningful keywords.
What are N-Gram Phrases?
N-grams refer to sequences of consecutive words. 1-word (unigrams) check single terms, 2-word (bigrams) analyze short concepts, and 3-word (trigrams) reflect specific long-tail keyphrases.
