Buying psychology

Design is what your visitor does next.

We map the path from first glance to purchase as five decisions. Behind each one is a question your visitor asks. Design based on buying psychology answers each question at the point where it arises.

  1. Notice

    Is this for me?

    Image and first line show who the product is made for: on the page, and before that in the ad and the search result.

  2. Stay

    Am I in the right place?

    The top of the page shows your visitor where they are and how to move on. The page delivers what brought them here.

  3. Want

    Why this product?

    The difference from the alternative is stated in one sentence, in your customers' words.

  4. Act

    What could go wrong?

    Reviews, trust badges and the return policy sit next to the price, where doubt arises.

  5. Return

    Will I buy here again?

    Delivery time and availability are stated honestly. Your customer holds you to that promise when the parcel arrives.

Our method

Conversion optimization with the 545 method.

5 decisions lead to the purchase. 4 forces act on each one. In 5 steps we find the point where your store loses the most shoppers and redesign it.

20 review questions: 5 decisions times 4 forces

We map the path to purchase as five decisions. Each can be read from one metric. Only one of the five is made at checkout.

The same four forces act on each of the five decisions. Five times four gives a grid of 20 review questions. Three of the forces were described by the psychologist Daniel Kahneman (1934 to 2024), who was awarded the Nobel Prize in Economics in 2002. Psychology sets the direction. How large the effect is in your store, we measure.

In five steps we find the point where your store loses the most shoppers and redesign it. We work in cycles of 6 months.

01 / 05Deci­sions

Notice

Is this for me?

Before anyone enters your store, they have decided whether to look or keep scrolling. Image and first line must show who the offer is made for. This decision can be read from the click-through rate.

In the store
Product tile in category and search (image, title, price, stars), plus page title and description shown in the search result.
Outside the store
Ad, search result, subject line. We check whether the promise there matches the page your visitor lands on. Landing pages and advertorials we design ourselves.

02 / 05Deci­sions

Stay

Am I in the right place?

On arrival, your visitor checks whether the page delivers what brought them here and whether the store looks trustworthy. Whether a page appeals is decided in a fraction of a second. Read from the bounce rate of the entry page, meaning the share of visitors who leave right away.

In the store
Entry page (homepage, category or product page): first screen, load time, mobile menu.
Outside the store
Landing page or advertorial in front of the store: we design it. Phone, retail store and trade show booth are up to you.

03 / 05Deci­sions

Want

Why this product?

On the product page, your shopper compares: with the alternative, with the price, with what they already have. A good page states the difference in your customers' words and gives an honest reason to buy today, such as delivery time or availability. Read from the share of visits with a filled cart.

In the store
Product page: images, benefits, price with a reference value, reviews, variants.
Outside the store
Review portals, forums, comparison sites. We analyze these to match your customers' language. We cannot influence them.

04 / 05Deci­sions

Act

What could go wrong?

Anyone about to order weighs up at the end what they could lose: money, time, the effort of a return. Hesitating here is normal. The answers must be right where the order is placed. Read from the completion rate from cart to order.

In the store
Cart and checkout: total cost, payment methods, return policy, delivery time, mandatory information.
Outside the store
Payment providers, quotes by email, buy on invoice: up to you and your service providers. We check how it is announced in the store.

05 / 05Deci­sions

Return

Will I buy here again?

After the purchase, memory decides. In hindsight, the strongest moment and the ending count most, the duration hardly at all. Our working hypothesis: the memory of the last purchase is the first impression of the next one. Read from the repeat purchase rate.

In the store
Confirmation page, customer account, return information, post-purchase survey.
Outside the store
Delivery, parcel, returns and support are up to you. We analyze what customers say about them and show where it costs the next purchase.

01 / 04Forces

Ease

how much effort the next step takes

What is easy to grasp seems more credible. The more a shopper has to puzzle over, the more likely they postpone the decision. That is why we check whether every page has one clear primary action.

How it shows in the store
Long load times, unclear navigation, jargon, mandatory account, too many fields, several equally loud buttons on one page.
Technical term
Processing fluency (cognitive ease)

02 / 04Forces

Frame

what is in view, how it is worded and what it sits next to

People judge by what is in front of them. The same information works differently depending on how it is worded and which reference value sits next to it.

How it shows in the store
Shipping costs that only become visible late. A crossed-out price or the first price shown as the reference value. Benefits in the manufacturer's jargon.
Technical term
Framing, anchoring effect

03 / 04Forces

Loss

what the shopper fears losing

For most people, losses weigh more than gains of the same size. Our working hypothesis: taking a risk off the shopper often does more than one more argument. Whether that holds for you, we measure. We do not use fake countdowns or artificial scarcity.

How it shows in the store
Unclear return policy, surprise extra costs, missing payment method, uncertainty about size or fit.
Technical term
Loss aversion, endowment effect

04 / 04Forces

Approval

what other shoppers say and do

Those who are unsure follow others. Reviews correlate measurably with sales, weakly on average, and the number of voices counts more than the rating. We also check where those voices are placed.

How it shows in the store
Number and content of reviews, voices on delivery and service, trust badges, well-known clients, press. And the place where they appear.
Technical term
Social proof

01 / 05Steps

Measure

Where do we stand?

First we check whether your tracking is correct, meaning the measurement of visits and orders. With clean data we collect the metric for each of the five decisions, split by device and visitor source. No right decision can be built on wrong numbers.

Result
Five metrics you can trust.

02 / 05Steps

Narrow down

Where are the most shoppers lost?

We look for the decision where you lose the most shoppers in absolute numbers. A poor percentage at a point with few visitors weighs less. You see the order and the reasoning before we begin.

Result
One decision to start with, with the reasoning.

03 / 05Steps

Explain

Why there?

We check this decision against the four forces and show which one is at work: with customer feedback, data and a UX audit, meaning a review of the page for usability. In our experience, this is the step most often skipped.

Result
A hypothesis, meaning a testable assumption: if we change X, we expect Y, because Z. Or the honest finding that the cause is price, product range or traffic.

04 / 05Steps

Design

What do we change?

One hypothesis, one change. We redesign the spot, with copy, imagery and layout. We or your development team implement it, depending on the store platform.

Result
The new version, ready for the test. This is where what your customer does next takes shape.

05 / 05Steps

Test

Did it work?

In an A/B test where order volume allows: some visitors see the current page, some the new one. How many orders the test needs, we set in advance. Otherwise in a before-and-after comparison with the uncertainty stated openly. What clearly blocks shoppers, we fix without a test.

Result
What wins goes live and is rolled out to further pages. What loses, we document and tell you openly. Then step 1 starts again.

The path is a circle: the return is followed by the next purchase, every test by the next measurement. We look most closely where the most shoppers are lost.

Mobile design

The purchase is decided on the phone.

Most shoppers now arrive on their phone, and that is where the purchase is decided: on a small screen, with one hand. That is why we design for the thumb first.

Your contacts

You talk to the people who decide.

You run a company, so do we. That is why in the intro call you talk to one of the two founders and managing directors: David Pehl or Anas Elimani. Whoever talks to you also makes the decisions and stays your contact while our design and development team works on your store. Whether we can help you, we tell you openly. If the answer is no, you hear that too.

Before the intro call

Common questions about conversion optimization and working together.

Duration, cost, store platform: the short answers are here. Whatever remains open, we clarify in the intro call.

Clear up open questions

What does working together cost?

That depends on three things: the state your store is in, how much we are to take on, and which systems are connected to your store. A flat price that applies to every store would be a guess.

Bring to the intro call which platform your store runs on, how many products it carries and which systems are connected. Then we give you an estimate for your store right there.

How long am I committed?

For one cycle of 6 months. In the first month we check your tracking, after that each test takes weeks to months depending on order volume. Anything shorter does not produce numbers you can base a decision on.

After 6 months you decide whether to continue. Many of our clients have worked with us for over 3 years.

Do I need a lot of traffic?

For A/B tests, the number of orders matters more than the number of visitors. As a rule of thumb: to prove a difference of 20 percent, a test needs around 400 orders per variant, for 10 percent around 1,600.

Conversion optimization does not require that, the A/B test is only one method within it. If your order volume is not enough, we work with customer surveys, UX audits (a review of the page for usability) and before-and-after comparisons, and state the uncertainty openly. Whether an A/B test is worthwhile at your order volume, we tell you before the engagement.

What do you do differently from other agencies?

We start with your shopper's decision. The 545 method maps the path to purchase as five decisions and checks each against four forces from decision research. That is how we find the point where your store loses the most shoppers before we design anything.

Every change gets a reason beforehand: if we change X, we expect Y, because Z. We tell you about losers as openly as about winners. And you talk directly to David Pehl or Anas Elimani, the two founders.

What is the difference between conversion optimization and A/B testing?

Conversion optimization (CRO) is the whole program: we measure where your store loses shoppers, narrow down the spot, explain the cause, redesign the page and test the result. The goal: more of your visitors buy.

A/B testing is the measurement method within it. Some visitors see the current page, some the new one, and the numbers show which sells better. You can also book A/B testing on its own if your team already has its own ideas and designs and wants to test them properly.

Do you only work with Shopify?

No. How people decide does not depend on the store platform. That is why we also run audits and A/B tests for stores on Shopware, WooCommerce or other platforms.

Full implementation we handle in Shopify. On other platforms, your own development team implements the changes. If you want to switch to Shopify, we guide the migration.

We have our own team. What stays with us?

The hypothesis list, with every reason and every result. If your team has its own ideas and designs, we test them in an A/B test against the current state. Whether we or your development team build in the winners depends on the store platform and is settled before the first test.

If you want to bring optimization fully in-house, we train your team and hand over the list, tests and results.

What happens to rankings, integrations and ongoing sales during a Shopify Plus migration?

Your current store keeps selling while the new store is built behind password protection. Before the start, we define the scope in 19 points and map every connected system: ERP, CRM, point of sale, payment, shipping. If a ready-made integration exists, we set it up. If not, we build the Shopify side of the integration or a custom app.

For rankings we commit to a procedure, not a result: an inventory of all old URLs, a redirect plan, checks before launch and monitoring afterwards. For us, a migration is only finished when every old URL has a verified destination.

When do I see first results?

What clearly blocks shoppers, such as a usability error in the cart or unclear navigation, we fix early and without a test. In parallel, we check tracking and technology in the first month so that the numbers we build on afterwards are correct.

Reliable numbers from A/B tests take longer: weeks to months per test, depending on order volume. That is why we work in cycles of 6 months and tell you before the start how many orders a test needs in your store.

What happens in the intro call?

You talk for 30 minutes with David Pehl or Anas Elimani. You describe where your store stands, what you have already tried and which numbers you have. We ask questions until we understand your situation.

At the end we tell you openly whether we can help and how we would proceed. If the answer is no, you hear that too. There is no sales presentation, and no finished audit of your store either, 30 minutes are too short for that.

Technology changes. How people decide does not.

Let's talk about how your visitors decide and what your store can do about it. 30 minutes with David Pehl or Anas Elimani.
