Include files can also be handy for repeating standardized content such as payment policies, privacy policies, or other “boilerplate” business or legal language that is repeated in identical form in many places throughout a large site. Always look for opportunities to pull repeating content out of the page files and into an include file. If you ever have to change the boilerplate language, you’ll be glad you have to change just one file to update every occurrence of the text throughout the site.
