Search engines recognize search boxes on websites by using special HTML markup, such as the input
element with the type
attribute set to "search"
. The markup signals to the search engine that the text entered into the box is intended to be a search query, and should be treated as such. Additionally, search engines may also look for additional information in the surrounding HTML, such as the presence of a submit button or form, to determine the purpose of the search box.
