The dark cogs of the lead generation sites, explained by someone who helped build one

I’ve spent a good chunk of my career on the inside of something most surveyors only ever see from the outside.

The lead generation machine. The one you pay into every month when you buy leads from a comparison site. I helped build one of the UK’s fastest-growing surveying lead platforms, so I’ve seen exactly how it works from the engine room.

And I think you should see it too.

Not because I’m about to tell you the platforms are villains. They’re not. They’re just very good at something, and they’ve quietly made it feel complicated so it stays their job and not yours. What I want to do here is pull the curtain back a little. Show you how the machine actually runs. Because once you’ve seen it, you can’t unsee it… and you might start wondering why you’re renting something you could own.

The number you already know but try not to look at

You know your cost per lead. That’s the easy one, it’s on the invoice.

The number that actually matters is harder to look at, and I’d guess you already have a rough sense of it even if you’ve never written it down.

It’s not what you pay per lead. It’s what you pay per instruction you actually win.

Because that £15 lead didn’t come to you alone. It went to four or five firms at once. So you’re not really paying £15 to win a job. You’re paying for the four you lose as well as the one you win. Do that sum on your own numbers and the cost per instruction climbs to something that looks a lot less like a bargain… probably closer to £75 than £15.

None of that will be news to you. You feel it every time you’re the third surveyor to ring someone that morning, competing on price with two firms you’ve never heard of. What most people don’t get to see is the other half of the equation. The bit on my old side of the fence.

Now here’s the view from my old side of the fence

This is the part you don’t get to see from where you’re standing.

That lead cost the platform around £20 to generate. Maybe less. They ran some ads, sent the traffic to a page built to convert, captured the enquiry.

Then they sold it five times. At £15 each. That’s £75 of revenue from £20 of cost.

I’m not telling you that to make you angry at the platforms. Honestly, it’s a clever business. But I am telling you so you can see the shape of it clearly. You are not the customer in that transaction. The lead is the product, and it’s being sold to you and four of your competitors at the same time. The margin the platform makes is the margin you’re handing over for the privilege of not doing it yourself.

The turn (this is the important bit)

Here’s what took me a while to properly appreciate, even from the inside.

None of it is magic.

The platforms aren’t doing anything a surveying firm couldn’t do for itself. There’s no secret. There’s no proprietary black box. It’s a handful of things done well and done consistently, at scale.

Let me actually show you what those things are, because this is the value I promised.

A page built to convert, not just to look nice. Most surveyor websites are brochures. They convert somewhere between one and three visitors in a hundred into an enquiry. A page built properly for this, one job per survey type, the right questions, the right structure, converts closer to thirty. That gap is the whole game. It’s the difference between paying £40 for a lead and paying £10.

Ads pointed at the right intent. Not “surveyor near me” and hope for the best. A proper campaign structure that gets in front of people at the exact moment they’re looking, built on data about what actually converts in this market. This is the part most firms try once, lose a few hundred quid on, and give up. Fair enough. It’s fiddly. But it’s not a secret.

A way to qualify the enquiry before it reaches you. The platforms filter. They ask the right questions up front so the enquiry that lands is job-ready. You can do exactly the same thing, so you’re not on the phone to tyre-kickers all day.

Tracking, so you actually know your numbers. This is the one that changes everything. When you can see what each lead costs and what each instruction costs, you stop guessing. You find out which of your marketing channels actually work and which is quietly bleeding money. Most firms have never had this visibility. The platforms live and die by it.

That’s it. That’s the machine. Four things, done properly.

So what do you do with this

I’m not going to end this by telling you to go and build all of that tomorrow. Some of it’s genuinely involved, and you’ve got surveys to do.

But I’d love you to do one thing before you go back to your day.

Work out your own true cost per instruction. Take what you spent on lead generation last month. Divide it by the number of jobs you actually won from it. Not the leads you bought… the instructions you won. That number is the real one. And I’d bet it’s higher than you think.

If you want to see it laid out for you, I built a free calculator that does the sum and shows you the revenue you’re likely leaving on the table by renting leads instead of owning your own pipeline. No email wall, no catch. It’s at the top of the page here: getadvrtise.com

Have a play with your own numbers. Worst case, you find out you’re already running a tight ship and you can close this tab feeling smug.

Best case… you see the gap for yourself, and you start asking the question I started asking years ago from the other side of the fence.

Why rent the machine, when you could just own it?
