Understand the intention someone has when using a certain keyword. Write informational content when people look for facts or inspiration, or product descriptions when people look for products.
Cluster keywords based on their topic, not with Natural Language Processing (NLP) but based on search engine data. Understand how search engines combine keywords based on search behaviour.
Build a logical site structure based on the clustered keywords. Gain insights in which clusters are related and which are not. A logical sitemap is beneficial for search engine ranking.
