External Pages
Some pages on your domain are not WordPress content: a static landing page, a separate app at /app/, a legacy section served by another system, or a shop running on a different platform under the same domain. WordPress does not know they exist, so no WordPress sitemap lists them. The external pages sitemap fills that gap.
Turn it on
- Go to Super Speedy > Sitemaps > XML Sitemaps.
- Under Enable following sitemaps, tick External (non-WordPress) pages.
- Click Save Changes.
An External pages section appears on the same tab as soon as you tick the box, and after saving, page_external.xml is listed in your sitemap index.
Add a page
- In the External pages section, click Add new page.
- Fill in the form:
- Absolute URL to page – the full URL, for example
https://example.com/app/. It must start with your Site Address, and each URL can only be added once. - Change frequency – pick a value, or choose Calculate using “Last modified”.
- Priority – 0.1 to 1.0.
- Last modified (time is optional) – the date the page last changed, in your site’s local timezone (Settings > General).
- Absolute URL to page – the full URL, for example
- Click Save Changes in the dialog.
Click Show/Hide external pages to see the list, with an edit and a remove button for each entry.
URLs on another domain or subdomain are rejected with “Please provide an absolute URL under your domain”. A sitemap may only list URLs on its own host. For a separate subdomain, give that subdomain its own sitemap and submit it separately in Search Console.
Keep “Last modified” honest
Google uses <lastmod> to decide whether to re-crawl a page. Update the date when the page changes, and leave it unchanged when it has not. A date that moves without the page changing teaches Google to ignore it.
Adding many pages, or pages that change often
Typing pages in one at a time suits a handful of URLs. For dozens, or for URLs another system generates, add them in code with the sssm_gxs_external_pages filter. See Developer Reference. Pages added in code and pages added on this screen appear together in page_external.xml.
If the other system already produces its own sitemap file, add that whole file to your index instead with sssm_gxs_external_sitemaps, described in the same article.
After adding pages
If caching is on, click Flush Cache so page_external.xml and the index rebuild with the new entries.
