To specify an expiry date (so if the page is time-sensitive and should be removed from a search-engines database after a period of time), click ‘Expires in’ checkbox and select the timeframe (minutes, hours, days, weeks, or months) using the popup timeframe menu. Lastly, type a value in the number field. Search Indexing Robots may delete expired documents from a search engine, or schedule a revisit. If the ‘Expires in’ box is left unchecked, your page will not include an expiry date.
