The Popular Search Terms pages lists search terms which have been entered by visitors to your store, and ranks them by popularity. Search terms are listed in a “tag cloud” format, where the size of the text indicates the popularity of the term. The link to the Popular Search Terms page is located in the footer of your store.
By default, Popular Search Terms is enabled as a search engine optimization tool, but has no direct connection to the catalog search process. Because the Search Terms page is indexed by search engines, any terms included on the page will help improve your search engine ranking, and the visibility of your store.
