Feature phone sitemaps

You should not create a feature phone sitemap unless you have a specific feature phone version of a page designed for feature phones (non-smartphones).

You can create a mobile sitemap for feature phones using the sitemap protocol along with an additional tag and namespace requirement. You can create a separate sitemap listing your video content, or you can add information about your video content to an existing sitemap—whichever is more convenient for you.

A sample mobile sitemap that contains a single entry is shown below.

<?xml version="1.0" encoding="UTF-8" ?>
 <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
         xmlns:mobile="http://www.google.com/schemas/sitemap-mobile/1.0">
    <url>
        <loc>http://mobile.example.com/article100.html</loc>
        <mobile:mobile/>
    </url>
</urlset>

Please be aware of the following guidelines for making a mobile sitemap:

If you choose to use a sitemap generation tool, first check that it can create mobile sitemaps.
Include the <mobile:mobile/> tag to make sure that your mobile URLs are properly crawled.
URLs serving multiple markup languages can be listed in a single sitemap.
Search Console automatically detects and supports the following markup languages for mobile content: XHTML mobile profile (WAP 2.0), WML (WAP 1.2), cHTML (iMode)

XML namespace

xmlns:mobile="http://www.google.com/schemas/sitemap-mobile/1.0

Feature phone tag definitions

Tag	Required	Description
`<mobile:mobile/>`	Yes	Put this singleton tag inside any `<url>` tag to indicate that the URI serves content optimized for feature phones.
