Step 1: Research Your SEO Opportunities

Run your target keywords in tools like SE Ranking and go through those keywords to identify those that may benefit from a video explanation.

SE Ranking will alert you of keyword difficulty (i.e. how hard it is going to be to rank your content on the first page) and generate the SERP snapshot showing some recent movements.

Keyword clustering is a solid technique that will help you identify topics behind those keywords and optimize your future video for a group of search queries rather than an individual keyword string.
