Our analysis

AI-assisted

The Sitelinks Search Box is a WordPress plugin that adds JSON-LD schema markup for the Google Sitelinks Search Box on your homepage. This feature allows users to perform site-specific searches directly from Google search results without needing to navigate to your site first. However, as of November 2024, Google no longer supports this feature, making the plugin redundant.

The plugin was initially useful for enhancing user experience by providing a direct search option for your content. It is suitable for website owners who want to implement this schema markup. However, with the retirement of the feature, its relevance has diminished significantly.

Best for: Website owners who previously wanted to implement the Sitelinks Search Box feature.

What it does well

  • Adds JSON-LD schema markup for Sitelinks Search Box
  • Supports multiple languages including English and Spanish
  • Easy to activate and use

Where it falls short

  • No longer supported by Google as of November 2024
  • Redundant for users of WordPress SEO by Yoast version 1.6 or newer

Verdict

While the plugin was useful in the past, its functionality is now obsolete due to Google's discontinuation of support.

From the developer

apasionados's own description of Sitelinks Search Box, lightly tidied.

PLEASE NOTE: Since November 2024 Google doesn’t support the schema for the Sitelinks Search Box anymore. After more than ten years Search Advocate John Mueller confirmed that the feature will be retired and the searchbox will not appear in the SERPs anymore.

Since November 2024 there is no need to install this plugin.

Quoting the post from Google Developers: While you can remove sitelinks search box structured data from your site, there’s no need to do so. Unsupported structured data like this won’t cause issues in Search, and won’t trigger errors in Search Console reports.

If you are using tis plugin and reading this readme.txt file, you can uninstall it.

xxx PLUGIN DESCRIPTION (until November 2024) xxx

This plugin adds the JSON-LD schema.org 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 youtube.com 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.

What can I do with this plugin?

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

After activating the plugin you only have to “Wait for Google Search algorithms to identify your site as a candidate for the new sitelinks search box”.
