Say you have 1000 pages of content and you want to change the footer or something in the header (suppose Google or Facebook now demand a new meta tag). Do you really want to change all those HTML pages by hand?

Also most web sites have navigation, lots of internal links will help web crawlers find everything and decide that it is important. Are you going to back and change them all by hand whenever you make a change?
