The first time I used the Free Online Generator there was a link or something at the bottom of the page right below the "XML Sitemap Content" box. There was something saying I had 9 broken links. To view the broken links I had to pay $5. I paid the $5 and was then shown which links in my sitemap were broken. I fixed those links and moved on. Since then I have yet to see the same message saying I have broken links. I figured my links have been fine, until the other day when I was viewing my sitemap through the sitemap.html file I noticed my redirect page with a bad link. What I am saying is, when I create my sitemaps I was expecting to see a message telling me I had broken links. I was expecting to see this message in the same place I originally saw it before I paid $5 to view the links.
Does the online generator no longer tell you if you have broken links?
