We design websites and build applications. Bring us a single task or a bigger project you’d like to work on together.
We review one product page and the cart. Find out where information is missing and which changes to test first.
Do visitors understand your offer? We review one service page and the path to an enquiry, even without analytics data.
Your prototype works in the demo. We review one user journey and identify what is missing before your next launch.

Vodafone compared two landing pages with the same appearance and functionality. The faster page displayed its largest content 31% sooner and achieved 8% more sales.
The test used a landing page with paid traffic. Development costs and net profit are not reported.

Baymard estimates around 35% potential for a higher order rate in large shops through better checkout design. The estimate is based on user tests and examined purchase flows.
A potential estimate, not a measured average redesign outcome. The figure cannot be applied to other shops across the board.

Matomo counts differently from your shop. The same questions return in the next meeting. The analytics data check investigates what the available figures can actually tell you.
View the analytics data checkThe selector is at the top. The size chart is hidden further down.
Choose a size
Size guidance beside the selector
This is what the change could look like. A specific test task then checks whether people find the guidance.
'The product page is confusing' gives developers little to work with. A useful finding identifies the exact location and describes what should change.
In this sample, selection and size chart are far apart. Someone searches, loses their place and has to return. After the change, the test task is: use your measurements to choose a suitable size. Do they now find the guidance without a hint?
Your team can verify this journey itself. Whether the order rate changes also requires a comparison of actual purchases afterwards.

We measure up to three page types under documented conditions and show your developer where to start.
A new design for one existing page, on desktop and mobile, with organised content and development notes.
Up to three agreed changes to your existing frontend. We work in a test environment and document the results.

The jobs platform reports 15% more organic visits after a year spent fixing issues affecting Google's crawling and indexing of its pages.

The GEO study measures the presence of sources in AI answers. Revised content, for example with citations and supported statements, achieved up to 40% more visibility in the research setup.
Visibility was measured, not clicks or revenue. The 2024 results do not predict performance in today's AI search systems.

Material, size or use: useful images answer questions that remain before buying. We plan imagery and interfaces to fit your offer.

Read the scope and add the suitable service to your selection. Sending an enquiry is free.
Enter your contact details and review your selection. We then clarify your plans and the documents needed in writing.
You receive the scope, price and timing in writing. Work begins only with your agreement.
We analyse, design or develop the agreed scope. You receive the result with a clear handover and room for follow-up questions.
After goods, shipping and other variable costs, the contribution margin remains. The ongoing additional costs of your improvement are then deducted.
10,000 monthly visits and 20 additional orders: the assumptions are €80 net order value and a 40% contribution margin. Monthly calculation once the effect starts:
Fictional assumptions: €1,000 for analysis, €1,500 for implementation and one full month without an effect. The assumed improvement stays constant from month two. Additional costs of €100 accrue every month from project start. No other savings.
11 × €640 − 12 × €100 − €2,500
Orders and margin matter for a shop. Enquiries also need a conversion-to-sale rate. Saved working time first creates capacity; only eliminated expenditure saves cash. The calculator guides you through your scenario.
Use your own figures
Which events does your tracking actually count? We check one analytics property for gaps and conflicting figures.
Hosting, tools and ongoing services: we organise up to ten cost items and include the work involved in a possible switch.
We implement one recurring workflow with n8n, Zapier or Make: up to three applications, one trigger and a clearly defined outcome.
From inbox to CRM, from a spreadsheet to the next system: a specific workflow lets us investigate which manual work can disappear and where approval is still needed.
Automate repetitive tasksYou do not need a finished brief yet. A situation you want to change is helpful: 'Customers keep asking which size fits' or 'Every order is entered manually twice'.
Define your project in the plannerNote one or two examples: a recurring question, an error message or a cumbersome step. For a new function, describe who will use it and which task it should complete.
Show us the affected page or your design. If figures conflict, name the report and period. To review text and usability, an accessible page is enough to start.
If someone already works on your website, the report should be useful to them. Tell us about existing requirements or planned changes. If we handle implementation, you receive a separate quotation.
Unsure which service fits your project? Briefly describe what you have in mind.
Ask your questionSAND & MEHR offers services for UX, design, development, 3D, analytics and AI automation. The service finder narrows down your needs with three questions. Or describe your project through ‘Ask an expert’ — we will help place it in context.
Yes. You can enquire about individual improvements, new interfaces, backend functions or complete applications. A check is not required if the task is already clear. For analysis packages, subsequent implementation is a separate order.
We work quickly with clearly defined tasks and short feedback cycles. Delivery time depends on the product, required documents and handover. We agree your specific date before commissioning. You can tell us your preferred date when clarifying the project.
No. We first check whether your project fits the described scope. You then receive a written quotation. Work begins only when you accept it.
