Organic traffic is a cornerstone. But search engine advertising ensures visible placement in transactional searches. According to Bitkom analysis Search engine advertising plays a significant role in the digital marketing mix in Germany. Use both, depending on the search intent.

Marketplaces are an additional sales channel. BEVH The company reports renewed growth in online retail for 2024 and a double-digit share of its brick-and-mortar retail market.

Your market is constantly evolving. Devices, channels, and expectations are changing. UX is a process. Small tests, short cycles, and consistent learning loops.
Here's how to proceed
- Start a monthly UX test with real users.
- Log search terms in the shop. Optimize the zero-results first.
- Measure the percentage of sessions with interaction on product pages. Analyze click paths with heatmaps.

- Use wish lists and later reminders in the shop.
- Include a section for recently viewed items on each product page.

Here's how to proceed
- Enable automated rating requests after delivery.
- Show filters based on characteristics: size, fit, area of use.
- Use the Q&A section on the product page. Clarify any concerns before purchasing.

- Load JavaScript only when needed. Defer, async, critical CSS inline.
- Trade fair with web vitals. LCP, INP, CLS. Working on the biggest outliers.

- Offer precise cookie selection. No mandatory checkboxes.
Myth 13: The system generates the revenue
Technology is a means to an end. Revenue is generated through offering, trust, processes, and reach. Changing the system doesn't solve a strategy. It rarely removes the underlying obstacle.
Here's how to proceed
- Define goals in numbers. Revenue, contribution margin, inventory turnover.
- Derive requirements from this. Payment methods, search, PIM, ERP integration.
- Check the platform selection later. First the homework, then the switch.
Myth 14: Social media is sufficient as a sales channel
Social Media It builds reach and trust. The shop converts. The search engine captures ready-to-buy demand. HDE Insights This demonstrates the importance of search channels in the buying process. Use channels in combination.
Here's how to proceed
- Plan campaigns along the journey: discovery, comparison, purchase, engagement.
- Use UGC on product pages. Authentic, concise, and allowed.
- Link social media campaigns with clean landing page design.
Myth 15: Key performance indicators are dry, incidental information.
Without numbers, you're navigating blindly. A compact set is all you need: revenue by channel, gross profit, conversion rate, average order value, shopping cart abandonment, return rate, and repeat purchase rate.
Here's how to proceed
- Create a weekly report with fixed questions. What went well, what didn't, and what hypothesis follows.
- Define target ranges. Make timely decisions, stop mistakes early.
- Add qualitative signals. Support tickets, on-site search, reviews.

Excellent article! As a business consultant from Hamburg specializing in e-commerce, I can endorse every point. What I see most often in my practice is that companies massively underestimate the importance of data and analytics.
Excellent article! As a digital transformation consultant in Kiel, I see companies failing because of these myths every day. In my opinion, the worst is the belief that you can simply transfer your offline catalog to the internet without any changes.
Fantastic article that finally dispels all the myths! As the owner of a small manufactory for handmade soaps near Hamburg, I resisted online sales for a long time, precisely because so many of these myths were circulating in my head.
As the managing director of a B2B company in Neumünster, I'd like to add an often overlooked aspect: B2B e-commerce is a completely different ballgame than B2C! Many people think they can simply transfer their B2C strategies. Wrong!
👏👏👏 THANK YOU! As an IT consultant from Hamburg, I see every day how companies approach e-commerce with completely wrong ideas. 'We just need a shop, IT will take care of the rest' – if I hear that one more time…
A huge thank you from Itzehoe for this eye-opening experience! We've been running an online shop for DIY supplies since 2018 and have had to painfully recognize every single one of these myths as false. The biggest misconception was believing that online retail can be done 'on the side'.
Excellent analysis! I'm still missing the myth that 'internationalization is easy'. We thought we'd simply translate our shop into English and sell worldwide. Well, different payment methods, shipping costs, customs, legal differences, cultural preferences… It's a nightmare!
Wow, this article should be required reading for all e-commerce beginners! As a marketing manager for a medium-sized company in Norderstedt, I've experienced pretty much every one of these myths firsthand over the past three years. The worst misconception was definitely that all you need is a beautiful online store and the customers will magically appear. Ha! Reality is quite different. We initially invested €50.000 in a state-of-the-art shop system – top-of-the-line, with all the bells and whistles. And then? A complete blank. Zero traffic.
Brilliantly written and so true! As the owner of a bookstore in Lübeck with an online shop since 2020, I can confirm every single point. We initially really thought we could Amazon Competing with others – how naive! Today we know: Our strength lies in our niche and personal consultation. We curate, recommend, and tell the stories behind our books. No algorithm can do that.
Greetings from Flensburg from a frustrated online retailer 😅 This article really resonates with me! Especially the myth about automation… Sure, you can automate a lot of things, but especially in customer service, you quickly realize: people want to talk to people, not chatbots!
Thank you for demystifying the topic! 🙌 The section on retargeting was particularly eye-opening. We burned through money for months because we thought more advertising equaled more sales. What a joke! Since we've become more targeted and truly understand our target audience, things are going much better.
As the owner of a sporting goods store in Kiel, I can only emphasize the point about mobile commerce. 68% of our orders now come from smartphones. Anyone who doesn't have a mobile-optimized website is throwing money away. But here too, the same principle applies: simply being 'responsive' isn't enough – the entire user journey needs to be designed with mobile in mind.
Finally, someone who speaks plainly! 👍 From my experience in the fashion industry, I can only confirm this. The biggest misconception is that you win with low prices. Quality and service are king!
A very insightful article! As managing director of a medium-sized company in Pinneberg that has also been selling online since 2019, I've learned the hard way that e-commerce is anything but a walk in the park. The myth of 'quick money' on the internet is truly the most dangerous. We initially massively underestimated how much continuous work is required. SEOContent marketing and customer service have to flow seamlessly. The product descriptions and photos alone took us months. Things are running well now, but only because we have two full-time employees dedicated solely to the online shop. What particularly annoys me is that many consultants promise you the moon. "With the right shop system, everything runs automatically"—what nonsense! Technology is just the foundation. The real key to success is strategic alignment and a deep understanding of the target audience.
As the owner of a small electronics store in Elmshorn, I can only agree! Especially the myth about the free ones. Shipping This has been on my mind for a long time. We've actually achieved better results since we started communicating shipping costs transparently instead of artificially including them in product prices. Customers appreciate the honesty more than I thought.
