What is a 404 page?
A 404 page is the error page shown when somebody requests an address that does not exist on the site — a broken link, a deleted page or a mistyped URL.
An old link inside an email, a product withdrawn from the catalog, one mistyped letter in an address — all three land in the same place: the 404 page, the server’s standard answer when the requested address does not exist. The code belongs to the HTTP protocol, and its occasional appearance is unavoidable on any living website. The problem for a business shows up in two forms. The first is volume: dozens of broken internal links signal neglect to visitors and to search engines alike, while pages deleted without redirects throw away traffic and rankings that were expensive to earn in the first place. The second is experience: a bare technical 404 is a dead end from which the visitor escapes with the back button, usually straight into a competitor’s tab. A well-considered 404 page reverses that, explaining in plain language what happened, offering search and useful links, and keeping the visitor inside the site. Monitoring these errors belongs to the monthly hygiene of any seriously administered website — and one technical detail, covered below, silently ruins many otherwise attractive error pages.

Why it matters for your business
Visitors kept rather than lost
A 404 page with search and useful links turns a dead end into a fork in the road — a share of the people who land there continue their journey on your site.
Structural problems caught early
Monitoring 404 errors exposes broken internal links and pages deleted by mistake — repaired in time, before they cost traffic and rankings.
A professional image even when things break
Even an error page communicates brand — a tidy 404 written in the company’s tone says the site is maintained by people who notice details.
Frequently asked questions
Do 404 errors damage a site’s Google rankings?
An isolated 404 for a page that genuinely no longer exists is normal and carries no penalty. What does damage is different: internal links pointing at 404s, which waste authority and confuse the crawler, and pages holding traffic or backlinks deleted without a 301 redirect, which is where rankings actually vanish. The rule is 404 for what is gone for good, redirect for anything with a successor.
How do I find out which 404 errors my site has?
Search Console’s indexing report lists the addresses Google finds missing, while crawl tools such as Screaming Frog scan the site and show broken internal links together with the page each one came from. The check is worth running monthly, and is mandatory after any change to the site structure or product catalog.
What should a good 404 page contain?
A short human message explaining that the page does not exist or has moved, a search box, links to the homepage and the main categories, and on a shop, popular products or current offers. The technical side matters just as much: the server must genuinely respond with status 404 rather than status 200 on an error page, otherwise search engines index the error as an ordinary page.
