Related keywords are processed by an apparatus and/or a system. A method of processing related keywords may include: receiving a primary keyword inputted by a user; and forming a spliced uniform resource locator (URL), which may be used for requesting related keywords based on the primary keyword. The method may further include establishing a link between an embedded window object in a current web page and a server using the URL to obtain the related keywords from the server. The embedded window object may create keyword list and may present the related keywords in the current web page. The method may further include: obtaining a related keyword selected by the user; and selectively adding the related keyword into an input box.
