Plone SEO: Page Title Tag Customization

Plone generates the <TITLE> tag from the document title and appends the site title to it separated by an em dash, for example: Politics — My Mutterings.

The Plone SEO add-on provides the capability of customizing the HTML title tag.

Problem

Where the user decides to override the page title, Plone SEO replaces the title tag in its entirety. This results in a page title without Plone site title, for example: My Custom Title.

The only alternative would be to add the site title explicitly, which would then no longer be configurable via the Site Setup.

Fix

This is just a quick and dirty fix implemented via a Diazo rule:

Those who use a Diazo themed Plone site can add the following rule directive to the rules.xml file:

This will append the Plone site title with a url-encoded em dash to any page title tag which it is missing from.

<replace content="/html/head/title/text()"
         if-content="//title[not(contains(., //*[@id='portal-logo']/@title))]">
    <!-- append " &mdash; <site title>" -->
    <xsl:value-of select="concat(., ' — ', //*[@id='portal-logo']/@title)"/>
</replace>
