How do I add the content type token in the page title?
Short answer: Simply insert the [node:content-type] token.

Longer answer:

The Page Title module modifies the title that appears in the &lt;title&gt; tag (which also displays in your browser's title bar. Just to clarify, this is separate from an individual node's title.

In the module configuration page, you will only see the raw token names displayed. The Page Title module will convert those tokens to human readable values on an actual node or "page". View the source of one of your nodes and check the &lt;title&gt; tag to see the actual values.

This module relies on the Token module in order to operate.

You can also get the Entity API module (and enable the Entity Tokens submodule) to get even more tokens that weren't picked up before.

Also: Be aware that the project maintainer has identified an issue with Fusion based themes. If your site falls into that category, temporarily switch to another theme such as Bartik to test out the page title module.
