Common questions

What is an optimal keyword density for SEO?

Most SEO practitioners recommend maintaining a primary keyword density between 1% and 2%. Writing naturally for humans while covering relevant terms is far more effective than forcing keywords.

What are n-grams and why are they important?

N-grams are sequences of N words. Unigrams are 1-word terms, bigrams are 2-word phrases (e.g. 'search engine'), and trigrams are 3-word phrases (e.g. 'search engine optimization'). Multi-word phrases reflect real user search queries.
