Pages absent from the sitemap rely entirely on crawl discovery via links, which can delay indexing of new content, especially on large sites or pages with few inbound links.
noindex or non-self canonical tags must NOT be included in the sitemapCompare the list of all canonical-url, indexable URLs on the site against the URLs in the XML sitemap. Flag any page that returns HTTP 200, has no noindex directive, has a self-referencing canonical, but is absent from the sitemap.
Add missing indexable pages to the sitemap. Remove pages that carry noindex, redirect, or non-self canonical tags from the sitemap. Automate sitemap generation so newly published content is included immediately.
Explain how missing sitemap coverage slows crawl discovery, which types of pages should and should not be included, and how to use Google Search Console to identify gaps.
Review metadata generation, rendered HTML, structured data, and response headers related to Include indexable pages in your sitemap. Flag exact routes or templates where search-facing output violates the rule, and describe how to verify the final page output.

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 22 cases were attempted. The headline lift of +9 percentage points is the difference between those two pass rates over the 22 comparable cases.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
Other measured skills in the registry, with their headline benchmark lift.
