Text links have a lot of value for optimal spidering, and site map has importance to help search engine robots reach website’s deeper pages.

Search engine robots cannot click a button, submit a form, pull down a menu, or perform any other type of online ‘user interaction’ that might be used by a human visitor. They are able to index the text on a page and click through hypertext links. A navigational text link is added to web pages (often located at the bottom of the page) to enable the search engine robots with another means to click through the links of web pages when it cannot access these other types of navigation.
