A YouTube-style creator video on a TV and an Instagram-style Reels post on a laptop sit behind a phone showing the post-purchase survey. “How did you hear about us?” has Influencer selected, “Which influencer?” has Maya Ortiz (YouTube) selected, and a card reads “Credited to Maya Ortiz, YouTube, Influencer”.
On the buyer’s phone, Fairing’s post-purchase survey for order #4821 asks “How did you hear about us?” with Influencer selected, then “Which influencer?” with Maya Ortiz (YouTube) selected above Maya Ortiz (Instagram). A card reads “Credited to Maya Ortiz, YouTube · Influencer”.

The problem

The influencer gets the view. Direct gets the credit.

The influencer gets the view. Direct gets the credit.

A buyer watches an influencer, doesn’t click, and searches your brand days later. Analytics files the order under Direct or Organic, and at renewal the influencer looks flat.

How it works

Ask the buyer. Credit the creator they name.

Ask the buyer. Credit the creator they name.

Survey asking “How did you hear about us?” with Influencer selected.

1

Ask on the order confirmation page

Asked after the order is placed, so checkout stays untouched.

“Which influencer?” with “maya” typed and Maya Ortiz (YouTube) highlighted above Maya Ortiz (Instagram).

2

Match the answer to the creator

One follow-up asks which influencer. Names suggest as the buyer types, so a partial name or handle finds the right one.

Orders view: Jordan said Influencer, Maya Ortiz. Order #4821 credited to Maya Ortiz, $84.00.

3

Credit the order to the creator

The order lands under the creator the buyer named, with its order value, ready for your renewal call.

“Migrated to Fairing from our previous post purchase survey partner about a year ago and has been such a great move. They’ve been great partners throughout the whole process and helping with some mapping challenges we were having with our Influencer activations and were able to find a solve. Would 100% recommend.”

Who brought new customers, not repeat buyers?

Ask the influencer follow-up only of first-time buyers, so every credited order is a new customer.

What does each influencer cost per new customer?

Divide the fee by the orders buyers credited to them, and compare the result with code redemptions alone.

Which sales did other ads take credit for?

See the orders buyers credited to a creator that Meta, TikTok or Google claimed as their own.

Influencer attribution questions, answered

Influencer attribution questions, answered

Influencer attribution questions, answered

How do I track influencer sales without a link or promo code?

Ask the buyer. After checkout, Fairing asks how they heard about you, then which influencer, so a buyer who watched and never clicked is credited to the creator they name. Keep your links and codes too, since many creators are paid on them, and let MMM size the channel as a whole.

What if the buyer doesn’t remember the influencer’s name?

They don’t need the exact spelling. Names suggest as the buyer types, so a partial name or handle finds the right influencer. A write-in that exactly matches a name on your list is recategorized automatically. Matching for misspelled write-ins is coming soon.

How long after an influencer post do people buy?

Often weeks later. Across 10,000+ YouTube creator integrations, Agentio found nearly 40% of views and 30% of clicks come more than 30 days after the video goes live, past most click windows.

How accurate is a self-reported answer?

It’s a sample: the buyers who answer, and what they remember. Fairing asks on the order confirmation page while the purchase is fresh. It doesn’t measure incremental lift on its own, so read it next to click tracking, lift tests and MMM, and rebook the creators who show up in both.

How many questions does a buyer have to answer?

Usually one question and one follow-up. Long influencer lists stay quick to answer, because influencer names suggest as the buyer types and a partial name finds the right one.

Does Fairing work for ecommerce brands that aren’t on Shopify?

Yes. Fairing runs on Shopify’s Thank You and Order Status pages and Shopify POS, plus WooCommerce, Salesforce Commerce Cloud, Recharge and headless stores through a Web SDK.
