Which of the given website design guidelines have been suggested by Google: (1) Containing a clear hierarchy and text links. (2) Each and every page must be reachable from at least one static text link. (3) When the site map is bigger than 100 or thus links, you must break the site map to the separate pages. (4) Keeping the links on a specific page to the reasonable number (that is, fewer than 100). (5) Employ less than 30 images or the graphics per page.
Can someone please help me in finding out the accurate answer from the above options.
