It’s been over ten years since Google announced the sitelinks search box in Google Search, and over time, usage has dropped. With that, and to help simplify the search results, Google will be removing this visual element starting on November 21, 2024.
This change will apply globally across all search results, in all languages and countries. This doesn’t affect rankings or the other sitelinks visual element, and won’t be listed in the Search status dashboard. Once Google stops showing sitelinks search box elements in Search, they will remove the Search Console rich results report for it and stop highlighting the markup in the Rich Results Test.
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 decide to remove sitelinks search box structured data, note that site names also uses a variation of WebSite
structured data, which continues to be supported.
