How to optimize On page with Longtail-Question-KWs?

Lets say you found a profitable KW: "How do you setup a WP theme?". Since the KW "setup a WP theme" might be too competitive, you want to go with the Longtail Question.

I have problems to optimize my On page thoughfor such types of KWs, because

1.) Many questions are just too long to put them in the URL, so your Permalink is not optimized.

2.) The longer the question is, the less you will rank for the more proftable KW at the end of the question (here: "setup a WP theme" or even "WP theme").

3.) Repeating the question again in the first 100 words and in the Meta description looks very spammy too me.


Do you have some tips how I can optimize the On page for those KWs without it looking spammy?

Put optimized pictures, youtubevideos, send outbound links to authority sites based on your topic question, h1 text your main keyword
