I have found numerous questions and blogs about including PDF files in an XML sitemap but cannot find a single one that gives a working example or which attributes to use:
What document types can be included in an XML sitemap?
Should I include PDF files in my sitemap.xml
On Google's Sitemap Guide it states:
The following table outlines the tags required for Sitemaps listing web URLs. To add more detailed information about specific content types, see video, images, mobile, News, and software source code.
Should .PDF be treated as a regular URL or News or is this out of date and there is one specifically for .PDF files?
Most of my PDFs are not news but brochures, case studies, and high resolution image files... speaking of should the high resolution image files be treating with <image:image>
then set the <image:loc>
to the .PDF?
