Improved Search Query Sitelinks for AdWords
Google has further improved its site links with an improved Query search function.
The feature puts a search box in the advert itself on Google SERP’s, which allows them to directly search your site, and sends the visitor through the Search result page of the site. This sitelink can be activated when people choose to search for your domain name, and Google reasons that a lot of such searches are for specific parts of your site. To enable this, you have to have a valid search engine feature enabled on your site and suitable markup on the home page.
Google has made this feature more prominent and includes autocomplete and a drop down menu of the most likely results, which will take you directly to that page on the site.
From Google’s Announcement “When users search for a company by name — for example, [Megadodo Publications] or [Dunder Mifflin] — they may actually be looking for something specific on that website. In the past, when our algorithms recognized this, they’d display a larger set of sitelinks and an additional search box below that search result, which let users do site: searches over the site straight from the results, for example [site:example.com hitchhiker guides].
If you implement the markup on your site, users will have the ability to jump directly from the sitelinks search box to your site’s search results page. If we don’t find any markup, we’ll show them a Google search results page for the corresponding site: query, as we’ve done until now.”
