The Jekyll’s introductory tutorial encourages you to create all pages with a header block that includes the key pair ‘title: A Page Title’. An unfortunate downside to this is that, under the default theme, every page is now added to your site’s auto-generated header - something that, as your site grows, you are unlikely to want to do.

Fixing this is simple; to exclude a page from the site’s header just omit your ‘title: A Page Title’ key pair.

For example:

---
layout: page
title: Blog
permalink: /blog/
---

… would add the page ‘Blog’ to the header and…

---
layout: page
permalink: /blog/
---

…would see it omitted.
