Trying to make site searchable within Google results When you type in the site "Airgas" in Google. It comes up with the company and then a store locator, tools & hardware and other categories, and then below it says "search airgas.com" with a textbox. How to do this for a website?
Only authority, popular sites can have a search box in search results, meaning you need to build more quality links for your site to have that. According to Google, the search box is chosen algorithmically based on metrics that measure how important the search box is to users.
Google gives priority to those websites which really needs to be authorized and will treat those as pretty well going..then may give search box which again indicates that particular thing can be found in that website directly rather searching in SE's !
