    Why this matters

    Including non-canonical, redirected, blocked, or noindex URLs wastes crawl budget and harms sitemap utility.

    A STARTING-POINT EXAMPLE

    Hypothetical standard operating procedure

    Adapt this example to your site, access, tools, and change process. It is our suggested procedure, informed by the sources below.

    1. Download current sitemap XML file for review.
    2. For each URL, verify it returns a 200 HTTP status with no redirects.
    3. Check that URLs are not blocked by robots.txt rules.
    4. Confirm pages are not marked with noindex meta tags.
    5. Ensure each URL has a canonical tag pointing to itself, not another URL.

    Watch for

    Including URLs that return redirects, 404s, or have noindex tags confuses crawlers and impairs indexing signals.

    Definition of done

    Sitemap contains only canonical URLs returning 200 status, not blocked or noindexed, with self-referencing canonical tags.
