  • Navigational: When there are direct searches for a brand, company, website, or a person, then it is known as a Navigational Keyword. Eg:  Adidas, Starbucks, Baskin and Robins.
  • Informational: This is a vast category and it represents the people looking for quick answers like phone numbers, recipes, news, and sports scores.
  • Transactional: These searches are largely used to buy a product or service online. Eg: Making a purchase, signing up for a premium content
