How to extract keywords from text on a page?

Question

Search Engine Optimization

Hello. Interested in the question, how can I extract keywords from the text on the page?
Keywordplanner extracts keywords completely from the entire page - everything gets there in a heap, starting from the menu and ending with the text of the page. You have to clean everything, everything takes a lot of time.
Maybe there is a method how to extract keywords from the text on a certain page?
I will be very grateful.
