You can start with the 3 stages of your customer’s journey: awareness, consideration, action and align each stage with relevant keywords that reflect the user’s intent.

To find the search intent of a keyword, I recommend using the tool SEMrush or Free keywords Generators. The image below shows how I map the different steps of the customer journey (1) with the different keyword intent (2) and what kind of keywords I am optimizing for (3).
