seo/update-system-page-seo changes the SEO title templates for the search results and 404 pages.
These pages have no content, so the template is the only thing that decides what a search engine or a browser tab shows.

How it works
Both pages are noindexed by default, so this is not really an SEO change. It is a change to what a person sees in a tab, in their browser history, and in a bookmark.
That is worth doing well on the 404 in particular. Somebody who lands on a 404 has already had a bad experience, and a tab reading “Page not found – Example” at least tells them where they are.
The search page title can carry the query term through a template variable, which turns a generic tab into a useful one when somebody has several searches open.
Yoast titles and descriptions are templates — patterns like %%title%% %%sep%% %%sitename%% expanded per page — rather than literal strings.
Idempotent.
Input

What comes back

updated | array | Which templates changed. |
success | boolean | Whether the call completed. |

Example
Ask your assistant:
Set a better title for our 404 page.
It resolves to one call:
{
"ability": "seo/update-system-page-seo",
"parameters": {
"error_title": "Page not found %%sep%% %%sitename%%"
}
}Worth knowing
- Both pages are noindexed by default — this is about people, not search engines.
- The search template can carry the query term.
- Nothing else decides what these pages are called.
- Idempotent.
