Depends on your goal.

If your only goal is the first page of Google, then try to optimise your content, improve the user experience, and improve your website's performance. Additionally, you can build some backlinks to help it out.

If you target crazy keywords that are already difficult, it's going to be complicated. You'll need PBN links in combination with perfect On-page SEO, high-quality content, and patience.
