Shopmacher take stock: these are the ten biggest weaknesses of online stores
1. Complex tool ecosystems lacking strategic integration.
Many online shops do not consist of one system, but of a network of shop software, ERP, PIM, CRM, CMS, payment gateways and marketing tools. However, these tools were often added as required – not according to plan. The result: confusing interfaces, duplicate data maintenance and error-prone synchronization.
Recommendation: Regularly record and evaluate the entire system landscape: Which tools are really necessary? Where does data pass through several stations unnecessarily? A strategic integration architecture creates transparency, reduces complexity – and saves a lot of effort in the long term.
2. Data models that do not fit together
Recommendation: Define a common semantic data model, bundle content responsibility and coordinate technical and editorial structures.
3. Obsolete code bases block further development
Many shops contain code from the early days – with improvised workarounds, never-documented in-house developments and libraries that are no longer maintained. These legacy issues make updates risky, block new features and make it difficult to train new developers.
Recommendation: Make technical debt visible and systematically reduce it. This means regularly refactoring code, removing unnecessary components and documenting critical areas. This creates a code base that not only runs – but can be further developed.
4. Hosting without foresight
Even strong brands underestimate how much strain campaigns, seasonal peaks or internationalization can put on hosting. A lack of scaling strategies then leads to loading times, downtime or high costs.
Recommendation: Agree load tests with the hosting partner, have resources scaled dynamically and use monitoring solutions for early detection of bottlenecks.
5. Sluggish pages despite powerful servers
Even with sufficient hardware, performance often falls short of expectations. The cause is then not the server – but complex rendering processes, unoptimized assets or unclear caching strategies.
Recommendation: Make page speed measurements routine, analyze rendering cascades and implement well thought-out caching for content and images.
6. Changes without safety net
Updates that go live on demand, manual reset processes and a lack of tests: many shops work operationally – but not robustly. Errors then quickly end up with the customer.
Recommendation: Establish automated deployment processes (CI/CD) with rollback function – supplemented by staging environments for risk-free tests.
7. Critical functions without reliable tests
Recommendation: Establish test strategies for all business-critical areas – from automated regression tests to regular exploration checks by the team.
8. UX optimization based on gut feeling
Home page teasers, filter logic, checkout route – many things are changed on instinct, rarely measured. The result: untested assumptions instead of well-founded decisions.
Recommendation: Make data-based UX a habit: Define a KPI framework, carry out A/B tests regularly and enrich findings with qualitative user feedback.
9. Security as a one-off measure instead of a process
Many shops rely on occasional penetration tests or framework specifications. But attackers are evolving – protection mechanisms have to keep up.
Recommendation: Establish security as a continuous process: Regularly check and secure authentication, role models, API access and input validation.
10. Accessibility as a nice to have
Although required by law, digital accessibility is a niche issue in many companies. Yet it doesn’t just affect a marginalized group – but millions of potential users.
Recommendation: Think about accessibility as early as the design process, check it with WCAG checklists or browser tools and ideally evaluate it with those affected.
Conclusion: If you want to grow, you have to look into the technology
Together with TÜV Austria subsidiary TÜV Trust IT, Shopmacher have developed their tried-and-tested Health Check into a comprehensive store audit. The audit model comprises over 60 technical test dimensions in the areas of backend, frontend and security. The audit sends a clear signal, particularly in the area of security: the tests are carried out directly by TÜV auditors.
Companies not only receive a neutral status report, but also reliable recommendations for further technical development – regardless of the store system used.
“A technical audit is not a know-it-all exercise with a raised index finger,” emphasizes Roitzsch. “It’s an opportunity to regain clarity on the basis of standards that were developed together with TÜV – and to work specifically on the future viability of the store.”

The countdown is on: On June 28, 2025, the Accessibility Reinforcement Act (BFSG) will come into force. But reality shows that many online stores are not yet ready. The new Accessibility Study 2025 reveals: The digital shopping world is still full of avoidable hurdles.
