404 page handling combines an accurate not-found response with useful help for the visitor. Pages disappear for ordinary reasons, including retired services and incorrect links. The aim is to distinguish legitimate removals from broken journeys, then guide people without pretending that every missing URL still contains valid content.
A missing page is not a site-wide penalty
An HTTP 404 tells clients that the requested resource is not available. A helpful error design should still return that status rather than a success response. Returning a normal-looking error message with status 200 can create a soft 404 problem. Search performance is more directly affected when valuable live pages accidentally break or important internal links lead to missing destinations. Focus on the role and history of the URL before deciding whether to restore, redirect or leave it removed.
Check both the message and response
Request an invented URL and a known retired page. Inspect their status codes, page titles and mobile layout. Provide clear wording, relevant navigation and a route to the site’s main services or contact form. Avoid an automatic timed redirect that prevents someone understanding what happened. Crawl internal links to locate references to missing pages, then fix their source. For high-value historic URLs, investigate prior content and relevant current replacements before choosing a redirect. Separate crawler noise from real customer journeys.
Inspect spelling mistakes in links the business controls. Correcting a broken menu or campaign destination at its source helps future visitors directly and avoids maintaining unnecessary redirects for errors that need not persist.
Respond accurately to a retired offer
Imagine a Perth business stops offering a specialised maintenance package. If an updated equivalent exists, a relevant redirect may help. If it no longer offers that work, a genuine 404 with clear navigation can be honest and useful. The team should remove links promoting the old package, review printed or campaign links it controls and preserve any necessary customer support information elsewhere. Monitor recurring requests to decide whether an explanatory replacement page would serve a real audience rather than merely change a report.
An SEO audit can prioritise missing pages by relevance and affected journeys.
Common questions
Should the 404 page be indexed?
It should return the correct error status. There is no reason to optimise an error template as if it were a normal service landing page.
Does fixing every unknown 404 help SEO?
Not necessarily. Random bot requests can produce harmless errors. Prioritise accidental losses, relevant incoming links and broken routes that actual visitors use.
Terms in this guide
- HTTP status code — A response code communicating the result of a request. Examples include 200 for a successful response, 301 for a permanent redirect and 404 for a resource not found.
- Redirect — A server or browser instruction that sends a request to another URL. Permanent URL migrations should avoid unnecessary chains and link directly to the intended destination.
- Internal link — A hyperlink between pages on the same website. Useful internal links connect related subjects, explain the site structure and give readers a relevant next step.
- Landing page — A page designed around a particular audience, campaign or action. Effective landing pages connect the visitor’s expectation with clear information and a relevant next step.
