How can a add a sub-page to a page?

I would like to add a page to an existing page, for example: http://example.com/page1/page2.html but the only way I can find for adding pages is to have them show as http://example.com/page1.html and then http://www.example.com/page2.html.

I'm not paying anybody for SEO as I feel that it's absurd to do so, and not having the ability to have sub-pages is detrimental to SEO.

Do any of you know if I can do this on Homestead, or should I just learn and use Wordpress. This service is becoming frustrating, although it's easier than anything I've used before.
