What exactly is a “Not Found (404)” error in Google Search Console?

When you see “Not Found (404)” inside the Pages or Coverage report in Google Search Console, it means that Google’s crawler requested a URL and reached a server response of “404 Not Found” (or equivalent). In simpler terms: the page was expected but isn’t there.

Unlike errored servers or missing domains, a 404 tells Google—or your visitor: “Yep, this URL once existed (or was referenced) but now it doesn’t.” For your site and brand, that can mean wasted links, frustrated users and lost opportunities.

Why should you care? Aren’t a few 404s inevitable?

Yes—some 404s are perfectly normal and benign. Google even says so—they expect some “gone or moved” pages. But here’s the kicker: when 404s accumulate, especially for pages that have inbound links or internal links pointing to them, they can silently drag down your site health, user experience and even search visibility.

Key issues include:

  • Wasting Googlebot’s time crawling dead pages instead of discovering new content.
  • Confusing users who click a link and land on a missing page (bad brand moment!).
  • Potential loss of link-equity when external or internal links point to pages that no longer exist.

How to find your 404 errors in Google Search Console

First things first—identify where the problem is hiding. Follow these steps via Google Search Console:

  • Log into your account and select the relevant property (domain or site).
  • Go to Indexing ? Pages (or in some versions Coverage ? Errors). You’ll see a breakdown of reasons pages aren’t indexed; look for the row labeled “Not Found (404)”.
  • Click that row to view a list of affected URLs. In many cases you can export the list (CSV/Google Sheets) for easier triage.

Tip: Don’t panic at seeing URLs you don’t recognize—some may be unimportant. We’ll talk about prioritisation next.

Which 404s do you actually need to fix (and which can you ignore)?

Not every 404 needs your full attention. Here’s how to prioritise:

  • High priority: URLs that once had traffic, inbound links, or are still referenced by your site or sitemap. These fixable issues can yield real SEO value.
  • Mid priority: Pages you purposely removed (expired offers, discontinued items) but which still have internal links. Clean these up or redirect.
  • Low priority: Random URLs, legacy site paths, or spam-referenced URLs with no significance. These may appear in GSC but pose little risk—Google often treats them as routine.

The step-by-step fixes that make 404 errors disappear

Here’s where the rubber meets the road. Tackle the following to restore crawl integrity and user experience:

Step 1: Determine what caused each URL to 404

When you view the error in GSC, click the URL and use the URL-Inspection tool (if available) to see when it was last crawled and what the referring page is (internal links count!). Often you’ll find:

  • A URL you removed without redirecting.
  • A page you moved/renamed (slug changed) but didn’t update internal or sitemap links.
  • A typo in a URL, sitemap entry or menu link.
  • An external site linking to a page you removed (track link sources if possible).

Step 2: Choose one of three actions

Once you know what’s causing the issue, pick the right fix:

  • Restore the page – If the content was removed by mistake and still valuable, bring it back at the original URL so the 404 disappears naturally.
  • Redirect the URL (301 preferred) – If the page moved or content now exists elsewhere, create a 301 redirect from the old URL to the most relevant destination (same topic, same intent). This preserves link equity.
  • Let it stay a 404 and remove references – If the page is gone permanently and irrelevant, leave it returning 404, but ensure it’s not referenced internally or via the sitemap. Then click “Validate Fix” in GSC.

Step 3: Clean up internal links and sitemap entries

If internal menus, blog posts or footers still link to that old URL, update those links to the new destination or remove them altogether. Also inspect your XML sitemap—if it lists deleted or moved URLs, remove them or mark them appropriately. Having dead links in your sitemap is like giving Google a treasure map to nowhere.

Step 4: Use custom 404 pages and good user experience

Even after you’ve cleaned up the major ones, some “true 404s” are inevitable. When they happen, make the user experience as friendly as possible:

  • Design a branded custom 404 page that includes a search box, suggested content links or homepage link.
  • Avoid redirecting every 404 to your homepage, unless it’s strongly relevant—Google may interpret that as content mismatch (a “soft 404”).

Step 5: Validate and monitor

In GSC, once you’ve addressed the URLs, click the “Validate Fix” button on each error entry so Google knows to recrawl. Then monitor for new 404s regularly—monthly or after any site overhaul. Staying on top means fewer surprises later.
