    Why this matters

    Early crawl detects redirect errors, 404s, missing canonicals, and noindex tags that could harm SEO.

    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. Use crawler tools to scan all migrated URLs within 24 hours of migration completion.
    2. Check HTTP status codes ensuring 200 for live URLs and 301 for redirected old URLs.
    3. Confirm no redirect chains or loops are present.
    4. Audit canonical tags for self-reference on HTTPS pages.
    5. Identify and fix any noindex directives not intended post launch.

    Watch for

    Delayed or no post-launch crawl can miss critical redirect or indexing problems causing traffic loss.

    Definition of done

    Crawl reports show all expected pages return 200, redirects are correct 301s, and no unwanted noindex tags.
