It is a good idea to show some of the visible structure of the site (i.e. the page hierarchy) to help visitors orient themselves. For non-visual users, an indication of the hierarchy could be given in the TITLE attribute of the ANCHOR element, <A>:
<A HREF="a.htm" TITLE="level 1">Welcome Page</A>
<A HREF="b.htm" TITLE="level 2">Home page</A> (main page)
<A HREF="c1.htm" TITLE="level 3">Products</A>
<A HREF="d1.htm" TITLE="level 4">Systems</A>
<A HREF="e1.htm" TITLE="level 5">System 1000</A>
