A CRO (Conversion Rate Optimization) checklist for your online shop

In the world of e-commerce, your online shop is far more than a digital storefront. It is a carefully designed stage where thousands of small decision dramas unfold daily. Every visitor is a potential protagonist whose story may end in the grand finale of a purchase or a quiet disappearance into abandoned baskets. What determines which scenario unfolds? It is not chance. It is science. It is art and craft together, known as CRO (Conversion Rate Optimization). Conversion optimisation is not a magic trick but a methodical process of removing barriers, frustrations and doubts on the customer's path to their goal. It is like preparing a perfectly lit, obstacle-free route straight to treasure. At Rebrandy , we have created these maps for clients for years. Today, we share our universal CRO checklist — a compass to audit your shop and discover hidden reserves of growth.

Before this fascinating search for lost conversions, here are our journey's key stages:

• CRO Foundations: We will explore why conversion optimisation is continual improvement rather than a one-off project, and how to think like a true analyst.
• Homepage: We will check whether your digital calling card clearly communicates value and directs traffic effectively rather than driving visitors away through chaos.
• Product Page: We will analyse whether your products are presented in a way that creates desire and dispels doubts.
• Purchasing Process (Checkout): We will identify the greatest ‘conversion killers’ in the basket and path to transaction completion.
• Technical and Psychological Aspects: We will discover how website speed, trust and subtle persuasion techniques affect sales growth.

Before ticking boxes: What thinking underlies effective CRO?

Before examining individual points on our CRO checklist, we must understand the philosophy behind the process. Effective conversion optimisation is not randomly changing button colours and hoping ‘something might work’. It is a methodical, data-based approach in a repeatable cycle inspired by the PDCA (Plan-Do-Check-Act) methodology:

1. Analysis and Research (Plan): Before changing anything, understand what happens on your website. Explore data from Google Analytics 4, analyse heatmaps and user session recordings, and conduct surveys. Your goal is to identify ‘bottlenecks’: places where users abandon in large numbers or encounter problems.
2. Formulating a Hypothesis (Plan): Use collected data to formulate a hypothesis. For example: ‘I believe removing compulsory registration from checkout will increase completed transactions by 10%, because it will reduce friction and user concerns’.
3. Implementing a Change (Do): Introduce one specific change testing your hypothesis. Test only one element at a time to know what affected the result.
4. Testing and Measuring (Check): Run an A/B test and collect data long enough for statistical significance. Compare the control, old variant with the test, new variant. A/B tests are CRO's heart, discussed further in what A/B tests teach us.
5. Analysis and Implementation (Act): If the new variant wins, implement it permanently. Otherwise, draw conclusions, formulate another hypothesis and restart the cycle.

Remember that CRO is a marathon, not a sprint. It is a culture of continual questioning, testing and learning. This checklist is your starting point: a map of potential problems and opportunities to investigate yourself.

Checklist #1: Homepage — Is your digital ‘hello’ convincing enough?

The homepage is your shop's most important and frequently visited page. You have only seconds to convince new users they are in the right place. It must answer three fundamental questions: ‘Where am I?’, ‘What can I do here?’ and ‘Why should I do it here?’

1. The Value Proposition (UVP) is clear and visible above the fold

Does the initial view, without scrolling, communicate what you do and what distinguishes you in one strong sentence? Avoid empty phrases such as ‘highest quality, best prices’. Be specific: for example, ‘Handmade leather bags with a lifetime guarantee’. A clear value proposition is the foundation of an effective brand communication strategy.

2. Navigation is simple, logical and follows Hick's Law

Is the main menu overloaded with dozens of options, or simple and guiding users? Limit main categories to 5-7. Use clear names and group products logically. This is the key to simplifying the website and guiding users towards their goal.

3. Search is visible and intelligent

Is the search field easily accessible? Does it offer suggestions and autocorrection? For many users, particularly those knowing what they want, search is the fastest route to a product.

4. CTAs (Calls to Action) are clear and action-oriented

Do main banners have buttons clearly explaining what happens after clicking? Replace ‘More’ with ‘View the collection’, ‘Discover new arrivals’ or ‘Explore offers’.

5. Social Proof builds trust

Do you present customer reviews, logos of well-known partner brands or media mentions? People trust people. Show that others have trusted you and are satisfied.

Checklist #2: Product Page — Are your products presented as treasures rather than warehouse stock?

The product page is where desire emerges. Users move from ‘I am browsing’ to ‘I want this’. Your task is to provide all information, dispel every doubt and make adding the product to the basket the only logical decision.

1. Photographs are high-quality, numerous and contextual

Do you offer a zoomable gallery of high-resolution photographs? Show the product from every angle? Most importantly, show it in use? A photograph of a dress on a model sells better than one on a white background. This is the foundation of image optimisation in e-commerce.

2. Product descriptions are persuasive and optimised for SEO

Are your descriptions merely dry technical specifications copied from manufacturers, or do they tell stories and focus on benefits? Use customers' language, answer potential questions and weave in keywords naturally. This is the art of creating product descriptions that sell and rank.

3. Price, availability and delivery options are visible at a glance

 Must customers search for this crucial information? It should sit beside ‘Add to basket’. Hiding delivery costs until the final step is a major reason for basket abandonment.

4. ‘Add to basket’ is impossible to miss

Is your CTA large, contrasting and prominently placed? This is the most important button on the page: it must shout ‘CLICK ME!’

5. Product reviews and ratings are visible and easy to add

Do you encourage customers to leave reviews? A review section is powerful social proof, building trust and helping other customers decide.

6. Cross-selling and upselling are subtle and helpful

Do you suggest complementary products — ‘Perhaps these shoes match this dress?’ — or better product versions? Used sensitively, these techniques can significantly increase average order value (AOV).

Checklist #3: Purchasing Process — Is the road to checkout a smooth motorway or a bumpy country track?

The purchasing process, basket and checkout, is the home straight. This is where most dramas unfold and where you lose most money. Every additional field, uncertainty and technical fault is a potential nail in your conversion's coffin. Make the process as fast, simple and painless as possible.

1. The basket is easily accessible and editable

Is the basket icon always visible? Does adding a product produce a clear message? Can customers easily change quantities or remove an item?

2. Registration is optional (guest checkout)

This is one of the most important points on the whole list! Forcing users to create an account before their first purchase invites basket abandonment. Always offer guest checkout.

3. The form is minimalist and requests only essential data

Do you really need a landline number and date of birth? Every additional field increases friction and reduces conversion. Ask only for what is essential to fulfil the order.

4. A progress indicator shows the customer's stage

Do users know how many steps remain? A simple indicator, such as Step 1/3: Details -> Step 2/3: Delivery -> Step 3/3: Payment, reduces uncertainty and encourages completion. This is crucial to shortening the purchasing journey.

5. You offer varied, popular payment methods

Alongside traditional bank transfer, do you offer quick payments (BLIK, PayU, Przelewy24), card payments and deferred payments (PayPo, Klarna)? More options increase the chance of matching customer preferences.

6. The whole process is secure (SSL certificate), and you communicate this clearly

Is there a padlock in the address bar? Do payment provider and courier logos appear at checkout? Build a sense of security at every step.

Checklist #4: Technical and Psychological Foundations — Is your shop a solid fortress rather than a house of cards?

The final, equally important part of our CRO checklist concerns your shop's foundations. Even the best-designed elements will fail if the website is slow, unsuitable for mobile or does not inspire trust.

1. Website speed is a priority, especially on mobile

Does your website load in under 3 seconds? Use tools such as Google PageSpeed Insights to diagnose and fix problems. Speed is fundamental, not an extra. Investing in Core Web Vitals optimisation pays back many times over.

2. The shop is 100% responsive and optimised for mobile

Have you browsed your shop on different smartphones? Are buttons large enough to tap? Is navigation comfortable? Most customers shop on phones: ignoring them is business suicide. Mobile is where shops make the most UX mistakes.

3. ‘About us’ and contact details are easily accessible and build trust

Can customers easily discover who is behind the shop? Find a telephone number and address? Show that you are a real company with real people.

4. Returns policy and terms are written in plain language

Are your terms legal gibberish? Simplify them. A clear, customer-friendly returns policy is one of the strongest ways to build trust and reduce purchasing concerns.

5. You use psychological principles to encourage purchases subtly

Do you use techniques such as:

• Social proof: ‘150 people have already bought this product’.
• Scarcity: ‘Only 3 units left in stock!’
• Urgency: ‘The offer ends in 24 hours’.
• Anchoring: Showing a crossed-out price beside the new, lower price.
  Used ethically, these subtle stimuli can significantly affect purchasing decisions. Read more in our article about how psychology increases conversion in e-commerce.
