Google Sitemaps reports pages that have internal and externals links pointing to any one page. Looking at pages with external links, I've taken note of the pages with only one external ~ which would be coming from the site map, which happens to be located off-site. Pages need external links to get a page rank from the search engines.

This does not represent all the pages with just a single external link. I only scanned the first 400 pages in the list, of 975 total. I'll check it again in a few months when it occurs to me again. Giving time for the list to be up-dated.

Remember that external links help a particular page, but also any other internal page that it links to.
