Does the module slow down the confirmation page?

No. The block is rendered server-side with the rest of the page, with no external call. Only one CSS file and a small script are loaded, and only on the confirmation page and the order details of the customer account.

Do I need cookie consent to use it?

The survey itself sets no cookie and loads no third-party script: the answer is attached to the order. Source detection, optional and disabled by default, writes the first source of the visit into the existing shop session cookie. Mention it in your cookie policy if you enable it.

What happens when a customer does not answer?

The order is still counted among tracked orders, which is what makes the response rate honest. The customer can answer later from the order details in their account, and receive the reminder email if you enabled it.

How many customers answer in practice?

It depends on the industry and the wording, but this kind of survey usually lands between 30 and 60 % on the confirmation page, and higher with the email reminder. The module reports your actual rate, period by period.

Can I change the answers?

Yes. The 11 answers created at install can be edited in the 8 languages, enabled or disabled, reordered by drag and drop, colored for the report, and you can add as many as you want. In multistore, each answer is enabled shop by shop.

Is the module GDPR compliant?

It implements the official psgdpr hooks: export of a customer's answers, and anonymisation on an erasure request, the answer staying in the statistics without personal data. Nothing is sent to a third-party service.

Does it work on PrestaShop 9?

Yes, from PrestaShop 8.0 to PrestaShop 9.x with the same ZIP, in multistore and multilingual setups. The module relies on ModuleAdminController and ObjectModel, with no Composer dependency.

Post-Purchase Survey PrestaShop: Channel Attribution

Post-Purchase Survey for PrestaShop 8 & 9: How Did You Hear About Us?

Your customers tell you where they come from, the report tells you what it is worth.

Since iOS 14, cookie refusals and the slow death of third-party tracking, your analytics attributes fewer and fewer sales. Self-declared attribution solves the problem from the other end: you ask the customer directly, at the one moment they are free, right after checkout. The module asks the question on the order confirmation page, records the answer in one click, then matches every channel with the revenue actually collected. Customers who leave without answering get a reminder email where each answer is a direct link.

The long version

Everything you'd want to know before you install.

A detailed look at how Post-Purchase Survey for PrestaShop 8 & 9: How Did You Hear About Us? works, why we built it the way we did, and the thinking behind the features above.

§ 01

Why declared attribution matters again

Between cookie refusals, blockers, intelligent tracking prevention on Safari and modelled conversions from ad platforms, a growing share of your sales is no longer tied to a reliable source. Meanwhile every platform happily claims the same sale. Asking the customer how they heard about you does not replace your tracking, but it gives a second measurement, independent from cookies and readable by everyone in the company.

§ 02

An answer collected at the right moment

The confirmation page is the one moment when the customer has finished buying and has nothing left to do. The module places a single question there, with answers as pills. One click is enough, the block is replaced by a thank-you message, and the answer is recorded for every order coming from the same cart when a delivery is split. Customers who skip can still answer later from the order details in their account.

§ 03

Revenue instead of a raw count

Counting answers per channel is not enough: one channel brings many small orders, another brings a few large ones. For every channel the report shows the share of answers, the tax-excluded revenue converted to the default currency, the average order value, the number of new customers and a revenue-to-answers index. Above 100, the channel brings more revenue than its share of answers suggests. An estimated revenue column extends the observed mix to all tracked orders, including customers who did not answer.

§ 04

The reminder that lifts the response rate

One customer in two leaves the confirmation page without answering. The module sends them a single email, after the delay you choose, in which every answer is a clickable link. The click records the answer with no form and no login. Sending is capped per run, ignores orders that are too old and respects the frequency cap, so it never turns into a mass campaign.

§ 05

What tracking never sees

Enable source detection and the module keeps the first UTM source or referring site of the visit in the existing shop session cookie, with no third-party script and no pixel. The report then crosses the declared answer with that detected source and shows the share of orders that arrived with no identifiable source at all. That is exactly the area no ad platform bills to anyone, and the one the survey lights up.
