notes for SEO breadcrumbs to use navigation label instead of page title in silverstripe:
open themes/themename/templates/BreadcrumbsTemplate.ss
<% if Pages %> <% if InSection(home) %><% else %> <li><a href="home/">Home</a></li> <% end_if %> <% loop Pages %> <% if Last %><li class="current">$MenuTitle.XML</li><% else %><li><a href="$Link">$MenuTitle.XML</a></li><% end_if %> <% end_loop %> <% end_if %>
