A dead end is a rescue moment
Most pages on your site are places a visitor is passing through. A 404, an error page and an empty search result are different: they are places a visitor has stopped, having asked for something specific and received nothing. The intent is unusually clear and the outcome is unusually bad, which makes these the cheapest conversions on the site to rescue.
They are also systematically under-served, because nobody designs them. The 404 page is inherited from a theme, the empty-search state is whatever the search component ships with, and neither appears in the analytics review that shapes the pages people do design. The result is a page that says some version of “not found” and offers a link home, which is not help — it is a shrug.
The three dead ends worth covering
They fail differently and deserve different handling.
- The 404. A link is broken or a URL was mistyped. The visitor often arrived from somewhere else — an old email, another site, a search result pointing at a page you moved.
- The empty search result. The visitor typed exactly what they wanted in their own words. This is the single most useful sentence they will ever give you, and the default response is to show nothing.
- The error page. Something on your side failed. This one carries a trust cost as well as a navigation cost, and it is the one where a human presence helps most.
Product availability is a fourth kind of dead end with its own dynamics; if that is your case, the out-of-stock guide covers it in more depth than this one does.
What the chat should say here
The generic invitation you run elsewhere is wrong on these pages. “Hi, can we help you find anything?” is a reasonable greeting on a category page and slightly insulting to someone staring at an error, because it ignores what just happened.
Acknowledge the dead end and offer the specific thing that would fix it. On a 404, that is an offer to find the page they were after. On an empty search, it is an offer to answer the thing they searched for, ideally echoing their own words back. On an error page, it is an acknowledgement that something went wrong on your end and a route to a person — and it should never claim the problem is fixed when nobody has checked.
Keep it short and make the exit obvious. Someone who has already been failed once has very little patience for a second obstacle, and an invitation that is hard to dismiss will read as the site failing them twice.
Do not make chat the only way out
The temptation is to treat the widget as the answer to the dead end. It is a good answer for people willing to talk to someone, and most people are not, especially when they are already mildly annoyed.
Fix the page first. A 404 should offer search, a route to the most likely destinations, and a way to report the broken link. An empty search should suggest alternative spellings or broader terms and show something rather than nothing. The chat invitation is a layer on top of a page that already tries to help, not a substitute for one.
This matters outside business hours, when an invitation is the wrong tool entirely. Make sure the fallback on these pages is honest about availability and leads somewhere that collects the visitor’s question, rather than implying that someone is standing by when nobody is.
Feed the dead ends back to whoever can fix them
The rescue is worth having, but the real value of chat on these pages is diagnostic. Every conversation that starts on a 404 is evidence of a broken path, and the agent can see which page the visitor came from. Every conversation that starts on an empty search contains a phrase a customer used that your site does not recognise.
Collect them. A monthly list of the URLs that generate 404 chats usually points at a handful of causes — a page that moved without a redirect, a link in an old campaign, a typo in printed material — and each one is a permanent fix rather than a repeated rescue. The empty-search phrases are the more valuable list of the two: they are your customers telling you, in their own vocabulary, what they expected you to have.
That list belongs with whoever owns content and search, not only with the support team. A rescue is a good outcome; not needing the rescue is a better one.
How MyLiveChat fits
Proactive invitations are triggered by rules including URL match, so an invitation written specifically for your 404 or no-results URL can run there and nowhere else — which is what lets the wording acknowledge the dead end instead of being generically friendly. Trigger rules and copy are set in the dashboard, so this does not need a change to the page itself.
On the agent side, the live visitor list shows the referring URL, the current page and the browsing path, so whoever picks up the conversation can usually see what the visitor was trying to reach before they landed on the error. That is what makes a fast, specific rescue possible rather than a round of questions establishing what went wrong.
What to measure
Start by finding out whether this is worth doing at all: count sessions that hit a 404 or an empty search result in a month. Most teams have never looked, and the number is usually larger than expected.
Then measure the rescue rather than the impression. Of those sessions, how many started a chat, and of those, how many ended with the visitor reaching what they wanted? Compare the exit rate on those pages before and after the invitation, and give it a full month before drawing conclusions, since dead-end traffic is lumpy and one broken campaign link can dominate a week. Keep the list of causes you fixed, and watch it shrink — a falling 404 chat volume is the success condition here, not a rising one.
