What are the three main types of search intent?

The three main types of search intent are Informational, Commercial, and Navigational. Informational intent means the user is looking for general knowledge or answers to a question (e.g., "how to tie a tie"). Commercial intent indicates the user is researching products or services with the intent to buy, but not yet ready to purchase (e.g., "best noise-cancelling headphones"). Navigational intent means the user is trying to reach a specific website or page (e.g., "Facebook login"). The other options list categories that are either too narrow, too broad, or mix intent types with search query characteristics.
