Wondering how to add a WordPress plugin google sitelinks search box?
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.
