For example: If you are doing niche research, but you don't know where to start. You will start with a trigger word to populate a list of ideas. These trigger words inherently have intent behind it.

Start with a word like "Change" and then narrow down the keyword difficulty to 10, and find the easy keyword you can start ranking, and slowly lead them to the stuff that is higher competition.

You can find a niche using the trigger word method.
