How do I rank top 3 for this keyword

Need an SEO expert here.

I want to rank on the first page for the the keyword:

"schengen visa international student"

I'm thinking of introducing a blog to my site: tripvisa.io

Whats the best strategy and how do i come up with titles. I'm thinking to use https://www.gomoonbeam.com/ to write the content

How many blog posts should i do?, What frequency should I release them
any info would be helpful.

remember my only goal is to rank for that keyword
