User search intent is a way marketers describe what a user wants to accomplish when they perform a Google search.

SEOs have understood user search intent to fall broadly into the following categories and there is an excellent post on Moz about this.

1. Transactional – The user wants to do something like buy, signup, register to complete a task they have in mind.
2. Informational – The user wishes to learn something
3. Navigational – The user knows where they are going

The Google human quality rater guidelines modify these to simpler constructs:

• Do 
• Know
• Go

As long as you meet the user’s primary intent, you can do this with as few words as it takes to do so.

You do NOT need lots of text to rank in Google.
