Where can I store common cross-site text (e.g. headings, titles etc.)

Question

I am developing a site that I want to hand over to a client once complete. The core page 'content' is manageable, but there are elements of content (common headings, titles etc.) that are shared across multiple pages & sections within the site, and I would like to give the client a single 'admin page' where they can set all of this information; there are about 25 bits of configurable content - all of them small strings.

You should build a theme settings page for all the "global" settings like social media url:s, phone number etc..

It could be something like this:

Or you can make a settings page with the new Customizer that comes with WordPress 3.4 so you can see your updates before you save it:

Answer 2

That would be a perfect use of the Transients API. Just store the values in transients and you can access them easily anywhere in your theme using:

get_transient('transientname');
