This plugin adds the JSON-LD markup for the “Google Sitelinks Search Box” on the homepage.

This new feature of the Google Search Engine was presented on the Official Google Webmaster Central Blog (05 Sep 2014 07:44 AM PDT). There is more info on the Google Developers Website.

With Google sitelinks search box, people can reach your content more quickly from search results. Search users sometimes use navigational queries -typing in the brand name or URL of a known site- only to do a more detailed query once on that site. For example, suppose someone wants to find that video about the guilty dog on YouTube. They type YouTube, or you-tube, or into Google Search, follow the link to YouTube, and then actually search for the dog video.

The sitelinks search box removes that extra step: a query for youtube displays a site search box in the sitelinks section, letting the user immediately search for that guilty dog video without having to click through to the site first.

If you use WordPress SEO by Yoast version 1.6 or newer, you don’t need to use this plugin, as this feature has been included in the version 1.6 update. There is more information in the FAQ section of the plugin.

Translating WordPress Plugins

The steps involved in translating a plugin are:

  1. Run a tool over the code to produce a POT file (Portable Object Template), simply a list of all localizable text. Our plugins allready havae this POT file in the /languages/ folder.
  2. Use a plain text editor or a special localization tool to generate a translation for each piece of text. This produces a PO file (Portable Object). The only difference between a POT and PO file is that the PO file contains translations.
  3. Compile the PO file to produce a MO file (Machine Object), which can then be used in the theme or plugin.

In order to translate a plugin you will need a special software tool like poEdit, which is a cross-platform graphical tool that is available for Windows, Linux, and Mac OS X.

The naming of your PO and MO files is very important and must match the desired locale. The naming convention is: language_COUNTRY.po and plugins have an additional naming convention whereby the plugin name is added to the filename: pluginname-fr_FR.po

That is, the plugin name name must be the language code followed by an underscore, followed by a code for the country (in uppercase). If the encoding of the file is not UTF-8 then the encoding must be specified.

For example:

  • en_US – US English
  • en_UK – UK English
  • es_ES – Spanish from Spain
  • fr_FR – French from France
  • zh_CN – Simplified Chinese

A list of language codes can be found here, and country codes can be found here. A full list of encoding names can also be found at IANA.
