Welcome to the Leaders Insights Podcast.

Today's episode, Measuring Influencer ROI Past Vanity Metrics, a CMO's playbook.

Every CMO I know brags about influencer campaigns pulling 10 million views.

So tell me straight, does a view mean anything?

Almost nothing.

A view means a phone was somewhere near a screen while a video auto-played.

That's the marketing equivalent of counting how many people walked past your store without

checking if a single one came in.

Harsh, but those are the numbers agencies put in the deck.

Of course they do, because they're easy to inflate and impossible to argue with.

Likes and follower counts are what we call vanity metrics, numbers that look impressive

and connect to nothing you can bank.

The follower count is the calorie label on a bag of chips.

Technically true, tells you nothing about whether it's good for you.

So where does a CMO actually start if they've been living on likes?

You start by picking one business outcome per campaign.

Revenue, retention, or brand equity.

The value of your name in someone's head.

Not all three.

If you chase all three at once, you measure none of them properly.

Fine, say I pick revenue.

How do I connect a TikTok video to a sale?

Three tools in order of honesty.

First, unique codes and links.

Which influencer gets their own, so you see exactly which sales trace back to them.

Cheap, clean, and it undercounts, because plenty of people see the video, buy nothing

that day, then Google you a week later.

So the code makes the influencer look worse than they are.

Right, which is why you add the second tool, post-purchase surveys.

One question at checkout.

How did you hear about us?

Everyone ignores this because it's low tech, but it catches the buyers the codes

miss.

HelloFresh has leaned on this, how did you hear about us question for years?

Precisely because their tracking links leak.

And the third?

Hold out testing.

The grown up version.

You run the campaign in some regions and deliberately go dark in others, then compare

sales.

If the influencer regions outperform, that gap is your real lift.

It's the only method that survives a hostile finance director.

That sounds expensive and slow.

It is.

So you only do it for your big bets.

The six-figure deals.

For everything else, codes plus the survey get you close enough.

You don't run a clinical trial to decide whether to buy the sandwich.

Let's talk retention, because you keep mentioning it.

Why shouldn't influencer care whether customers stick around?

Because the source of a customer predicts how long they stay.

Track the churn, the share of customers who cancel or stop buying, by which influencer

brought them in.

Jim Shark found buyers from fitness creators who actually use the product stuck around

far longer than buyers from a generic celebrity post.

Same acquisition cost, wildly different lifetime value.

The total money a customer spends before they leave.

So a cheap influencer with loyal followers beats an expensive one with a broad, indifferent

audience.

Often, yes.

And you'd never see that if you stopped at the first sale.

The Vanity Metrics crowd would have crowned the celebrity and quietly bled money for a

year.

What about brand equity, the fuzzy one?

How do you put a number on whether people think better of you?

Brand lift surveys.

You poll people exposed to the campaign, and a matched group who weren't.

And measure the difference in, would you consider buying this?

Vendors like Kantar sell this.

And all flag Chari, it's their product.

So treat their benchmarks as a starting point, not gospel.

But a 10-point jump in consideration is real signal.

Give me the one number a CMO should put on the dashboard tomorrow.

Incremental revenue per thousand dollars spent.

Per influencer.

Not reach.

Not engagement.

The actual extra sales you got that you wouldn't have otherwise.

Divided by what you paid.

And if an influencer can't produce that number?

Then they're an entertainer you're subsidizing.

Not a channel you're investing in.

Both can be fine.

Just know which one you're paying for.

So the takeaway?

Tomorrow, add one column to your influencer spreadsheet.

Incremental revenue per thousand spent.

Anyone who can't fill it in gets a hard conversation, not a renewal.

Done.
