If you don’t have any on the job experience, I’ll definitely want to see what websites you have worked on yourself.

These websites better;

1. Rank for some competitive keywords.
2. Have good quality and decently written articles on them.
3. Be designed in manner to generate leads, collect emails, or conversions.
4. Have some good backlinks.

This tells me you have a basic understanding of how to buy a domain, setup a WP website (easy using page builders like Elementor and Divi). and write content consistently.

Not everyone can take the time to properly setup a website targeting a niche.
