The most useful page on your website might be the one you never want anyone to see. It is the 404 page, the screen visitors land on when a link leads nowhere.
That sounds backwards, so picture a plumber in Burleigh who updates her website over a weekend. On Monday, a past customer taps a link in an old Facebook post to book a hot water check. Instead of a booking form, they get a blank screen that says 'Page not found'.
Most of those people do not go looking around. They go back to Google and ring the next plumber on the list. A good 404 page is how you catch them before they leave.
What a 404 page actually is
Every page on your site has an address. When someone asks for an address that does not exist, your website replies with a code. The code is 404, which is the internet's way of saying 'I looked, and there is nothing here'.
Your website still has to show the visitor something. If nobody has set it up properly, that something is usually a plain, ugly message from the hosting company. It has no menu, no logo and no hint of where to go next.
A custom 404 page replaces that dead end with a page that looks like your business and offers a way forward. It is a small piece of design work with a surprisingly practical payoff.
Why a missing page costs you enquiries
A visitor who hits a dead end rarely blames the link. They blame you. A broken page can make a business look careless, even if the rest of the site is spot on.
There is also a cost you cannot see. Think about where people click from: Google results, old social posts, email newsletters, directory listings, even QR codes on a flyer or ute. Each of those can point to a page that no longer exists, and each failed click is a lost chance to talk to someone who was already interested.
One honest note on search. A handful of 404 errors on a site is normal, and Google does not penalise you simply for having a 404 page. The trouble starts when pages that used to bring in traffic or links vanish without a replacement, because that traffic then has nowhere to land.
Where broken links come from
Most dead links are not dramatic. They creep in through ordinary changes. Here are the usual culprits:
- Renamed or deleted pages. You change 'Our Services' to 'What We Do' and the web address changes with it.
- A redesign or move to a new platform. New builds often create new web addresses, and nobody maps the old ones across.
- Typos in links. A missing letter in an email signature or printed flyer sends people nowhere.
- Expired offers and seasonal pages. The Christmas special page is deleted in January, but the link lives on in an old newsletter.
- Outdated listings. Directories and social profiles still point to addresses you stopped using years ago.
The common thread is that you changed something on your side and forgot the links living out in the world.
What a good 404 page includes
You do not need anything clever. You need a page that is calm, clear and useful. Aim for these elements:
- A plain, friendly message. Something like 'We cannot find that page, but we can help you find what you need'. Light humour is fine if it suits your brand. Do not blame the visitor.
- Your normal header and menu. It should feel like part of your website, not a separate error screen.
- Two or three useful links. Your main services, your contact page and your homepage cover most businesses.
- A phone number or enquiry button. Someone who was ready to book should be able to do it from here.
- A search box, if your site has many pages. Smaller sites can skip this.
Compare these two versions. Before: 'Error 404. The requested resource was not found.' After: 'That page has moved or no longer exists. Try our services, call us on the number above, or send an enquiry and we will sort it out.' The second one keeps the customer.
How to find your broken links in under 30 minutes
You do not have to guess which pages are failing. Work through this once and you will know where the problems are.
Check what Google has found
If you have Google Search Console set up, open the Pages report and look for entries marked 'Not found (404)'. This lists addresses Google tried to visit and could not load. Note the ones that look like real pages you once had.
Click through your own site
Open your menu, footer, and any buttons on your homepage, and click every one. It takes about ten minutes on a small site and often turns up a surprise or two.
Test the 404 page itself
Type your web address followed by a nonsense word, such as yourbusiness.com.au/test-page-nothing-here. You should see your own styled page, not a generic error. If you see a blank screen or a message from your host, you do not have a proper one yet.
Also check that the page returns a genuine 404 status behind the scenes. Some sites show a friendly message but quietly tell Google the page is fine, which muddies the picture. Your web designer can confirm this in a minute.
Redirects and the mistakes to avoid
A nice 404 page is the safety net. A redirect is the better fix when you know where a page has gone. A redirect automatically sends the visitor from the old address to the right new one. The usual type for a permanent move is called a 301 redirect.
For example, if your old 'Hot Water Repairs' page is now part of 'Plumbing Services', redirect the old address to the new one. The customer lands exactly where they should and never sees an error.
These are the mistakes we see most often:
- Sending every dead link to the homepage. It feels tidy, but it often confuses visitors and does not match what they were looking for. Redirect to the closest relevant page instead.
- Skipping redirects during a redesign. This is the biggest cause of lost traffic after a relaunch. List your old pages first and map each one across.
- Writing a joke-heavy page with no links. Humour is fine, but the visitor still needs a next step.
- Forgetting to check after changes. Make a quick link check part of any website update.
Redirects are not magic and you do not need them for every tiny page nobody ever visited. Focus on pages that had real traffic, enquiries or links pointing at them.
Things to do this week
- Type a nonsense address after your domain and see what your 404 page looks like today.
- Open Google Search Console and note any 'Not found (404)' pages that used to matter.
- Click through your menu, footer and main buttons, and write down anything broken.
- Ask your web designer to set up a friendly custom 404 page with your menu, key links and phone number.
