What do you actually get from a Messenger ad?
A thread. That is the entire asset. Some of the best ad creative in any Australian feed belongs to trade businesses, excavators and roofers and concreters who have paid a videographer properly, and then the whole thing ends with send us a message. When somebody clicks and starts a conversation, you get a chat window inside somebody else's app. You don't get a phone number. You don't get an email address. You get a first name that might be real and a conversation that stays alive exactly as long as the other person feels like replying.
When I went through 31 Australian trade businesses one by one, 10 of the 26 that were advertising were doing exactly this, which is written up in What we found auditing 31 Australian trade businesses. The moment they go quiet, it's over. You can't ring them. You can't text them. You can't send them photos of a similar job next week, or a quote, or anything at all, because there's nothing on your side of the table. The lead lives in Meta's app, on their terms, and it dies there.
Now compare that to a name, a mobile number and an email address sitting in something you control. That person can go quiet too, and they will, because people are busy. The difference is that you can do something about it. A thread is a conversation you're allowed to have while the other person is still interested. A phone number is an asset you own after they have gone quiet, and most jobs are won after they have gone quiet.
Why does this keep happening?
Because a Messenger conversation costs the person clicking almost nothing, the numbers look wonderful. The cost per conversation comes in low, the report fills up, and everybody involved can point at a healthy figure. Plenty of agencies deliver exactly this, often bundled with lead forms, and report the message count as the result.
I want to be fair here, because none of this is fraud. A message count is a real number. It's just a number, not an outcome. The near-zero cost of sending a message is precisely the problem: you collect everyone who was mildly curious in the three seconds before they scrolled on, and mild curiosity doesn't book jobs.
The part that stings is that the businesses doing this have often spent the most on their creative. The video earned the attention honestly. The destination throws it away.
So what counts as a lead?
Three fields. A name, a phone number, an email address, held somewhere you control and can act from. That's the minimum, and everything in paid advertising is ultimately a machine for getting those three fields into your hands, because they're what make follow-up possible. Follow-up is where the money is, and that's a whole article on its own.
There's a second-order effect too. When your ad's call to action asks for real details, the people who were never serious filter themselves out. You get fewer responses and more of them answer the phone. That trade is nearly always worth making, and hardly anyone makes it deliberately.
What should you run instead?
Two options on Meta, and which one is right depends on whether the person has met you before. For people who already know you, a lead form set up properly can be the right call. For cold traffic, a page you own. And if what you sell is something people search for when they need it, the right answer may be a different campaign altogether, on Google, where the click is somebody typing the problem in rather than somebody interrupted mid-scroll. Different moment, different campaign. Google Ads The lead form path has a default setting problem that quietly ruins most of the campaigns using it, and that's where to go next.
Are Messenger ads ever the right choice?
Occasionally. If your sale genuinely happens in conversation, if enquiries are simple and you or someone on your team lives in the inbox all day, a Messenger campaign can work as a retargeting layer for people who already know you. What it can't do is hand you anything durable. If the thread ends, so does the lead, and for a trade business quoting real jobs, that ceiling is too low to build on.
My agency reports Messenger conversations as results. Should I be worried?
Not worried, but ask one question: how many of last month's conversations turned into a phone number you could ring today? If the answer is a shrug, the campaign is producing activity, not assets. That's worth a conversation with them, and it's a fixable problem rather than a firing offence.
