    HTTP Status Checker — does your page return a healthy 200?

    Before a page can rank or be cited, it has to return a healthy `200 OK` — with real content behind it. This check reads the final HTTP status code after any redirects and flags anything that isn't a clean 200: a 4xx or 5xx error, a chain of redirects, or a soft-404 — a page that returns 200 but actually shows a "not found" message. Search engines and AI crawlers only index pages that respond correctly, so a broken status is an instant block.

    Check a page's HTTP status code

    Paste a URL — GEObubbly follows any redirects, reads the final HTTP status, and detects soft-404s, returning one clear verdict.

    In short: A healthy page returns a 200 status with real content. Anything else — a 3xx redirect, a 4xx error, a 5xx fault, or a soft 404 — means crawlers get something other than the page you intended.

    What does the HTTP status check verify?

    It reads the final HTTP status code the URL returns after following any redirects, and confirms it's a genuine success response with real content. It distinguishes between several cases:

    • `200 OK` with real content — the healthy state; the page is eligible to be indexed.
    • 3xx redirects — a single clean 301 to the final URL is fine, but a chain that resolves to 200 is a warning (it adds latency and risk).
    • Soft-404 — a page that returns 200 but whose content is a "not found" or error message; engines may treat it as an error and drop it.
    • 4xx / 5xx — a client (404, 403) or server (500, 503) error; the page can't be indexed.

    How is it evaluated, and how is it scored?

    GEObubbly requests the URL, follows the redirect chain to the final destination, and reads the status code there — then inspects the response body to catch soft-404s (a 200 paired with error-style content). It's a core check worth 3 points in Crawlability & Indexability, because a page that doesn't respond cleanly can't be crawled, indexed or cited no matter what's on it.

    Why the HTTP status code matters for SEO and GEO

    The status code is the page's handshake with a crawler: a clean 200 says "here's a real page, go ahead and index it." Anything else interrupts that. A 404 or 500 means the page isn't available, so it drops out of search and can't be cited by AI engines. The sneakier problem is the soft-404 — a broken or empty page that still returns 200, so monitoring tools think it's fine while search engines quietly de-index it for thin or error content. Redirect chains add their own risk: extra hops slow the page and give impatient AI fetchers more reasons to give up before reaching it. Returning a real 200 for every page you want found is the most basic crawlability requirement — get it right, then the rest of the Crawlability & Indexability signals can do their job.

    How this check scores
    Pass: 200 OK with real, substantive content.
    Warning: a 3xx that resolves to 200, or a suspected soft-404.
    Fail: a 4xx or 5xx — the page is broken or missing.

    FAQ

    200 OK is the HTTP status code a server returns when a page exists and loaded successfully — it's the "all good, here's the content" response. It matters for SEO and GEO because search engines and AI crawlers only index pages that respond with a genuine 200; any error code means the page isn't available to be stored or cited. A clean 200 with real content is the baseline requirement before any other ranking or AI-visibility factor can even come into play.
