Missing XML sitemap: what it is and how to fix it
What it is
No sitemap to tell search engines what exists.
Why it matters to a client
A sitemap is the fastest way for a search engine to discover new and updated pages, especially on a site without strong internal links.
How to find it
Run an AuditOpti free audit, or crawl the site with any crawler and filter the results by status code. In Google Search Console, the Pages report under Indexing lists the same problems from Google's side.
How to fix it
Generate an XML sitemap, reference it from robots.txt, and submit it once in Google Search Console.
- 1In the SEO plugin (Yoast, Rank Math or SEOPress), open the page's SEO panel and correct the setting described above.
- 2If the problem repeats across a post type, change it once in the plugin's template settings rather than page by page.
- 3Clear any caching plugin afterwards, then re-check the live page in a private window.
How AuditOpti prioritizes it
AuditOpti scores this as medium severity by default, then multiplies it by how many pages are affected — one page is not the same problem as a hundred. After that, the AI re-ranks it against everything else on the site by likely business impact, so a medium-severity problem on a service page can outrank a critical one on a page nobody visits.
