What 404MEDIA delivers in e-commerce
404MEDIA is an e-commerce agency based in Germany. We have worked with shop owners in Berlin, Brandenburg, across Germany and across Europe for many years, with a focus on four systems we know from the inside: PrestaShop, WooCommerce, Shopware and Shopify. We develop shops, make them fast, make sure they get found and connect them to inventory management, marketplaces and AI.
An online shop is not a project that is finished after go-live. It has to run, grow and adapt to the market and the technology. That is why we build shops that are still maintainable in three years and support them afterwards: with updates, SEO, integrations and automation.
Shop development
New shop or relaunch: concept, data model, category structure, design implementation, modules and plugins, integrations, data migration, legal texts and checkout compliant with German and EU law, testing, go-live. With a focus on page speed and maintainability so the shop still runs after the next update.
Shop SEO
Search engine optimisation specifically for online shops: category structure based on search behaviour, faceted navigation without duplicate content, product data, structured data (Product, Offer, Review), internal linking, page speed, images, buying guides. Systematically through templates and rules. German page: Shop-SEO.
Performance and conversion
Fast shops sell more. We measure Core Web Vitals, fix the causes in theme, modules and hosting, and optimise checkout, product pages, search and filters so more visitors buy. With measurement before and after every change.
Integrations and automation
Inventory management, ERP, PIM, payment providers, shipping, marketplaces, price comparison, newsletters, accounting. We build stable interfaces with logging and error handling and automate data maintenance, on request with AI support: product texts from manufacturer data, categorisation, answering customer enquiries.

How a shop project runs
- Audit. Technology, data, processes, numbers, competition. For existing shops: version, modules, theme, performance, errors, SEO status. We find the points with the biggest leverage.
- Fixed-scope offer. You know in advance what it costs and what you get. Running costs for hosting, licences and apps are included in the calculation.
- Implementation in stages. Each stage is tested on a staging system and approved by you. A visible result every two to three weeks.
- Go-live. With a complete redirect map for URL changes, automatically tested against all old URLs. Monitoring in the first weeks.
- Care. Updates, security, SEO, integrations, further development. With a fixed contact person.
Relaunch and migration without losing rankings
A shop relaunch is the most common cause of massive losses in organic search. URLs change, categories are restructured, redirects are missing, product texts get lost. We support every relaunch and every migration between systems with an SEO review beforehand, a complete redirect map and monitoring of Search Console after go-live. Rankings, backlinks and revenue are preserved.
AI in e-commerce
Language models solve tasks in retail that used to be left undone: product descriptions for thousands of items, translations, attributes from data sheets, categorisation, answering standard enquiries, product advice via chat. We build this into your shop, with review steps and approvals so the quality is right. More under artificial intelligence.
Who this is for
Retailers with an existing shop that is too slow, ranks poorly or has errors. Companies planning a new shop or a relaunch. B2B companies digitising their sales. Brands that want to sell directly. Shop owners whose inventory system, shop and marketplaces do not talk to each other. International brands entering the German market.
Why 404MEDIA
We are developers. We solve problems in the code instead of in a ticket to a third party. We combine shop technology with SEO, AI and integrations so you do not have to coordinate three agencies. We work with four systems and have no preference we need to sell you. And we talk openly about costs and risks before you decide.
Our ambition: to be among the best e-commerce agencies in Germany. Not through size, but through shops that run, get found and sell.
Frequently asked questions
Which shop system do you recommend?
It depends on catalogue, processes and budget. PrestaShop is strong for large catalogues and B2B, WooCommerce suits WordPress websites with a manageable catalogue, Shopware is the choice for demanding setups in the German-speaking market, Shopify for a fast start without your own infrastructure. We advise based on your requirements, not our preference.
Can you take over an existing shop?
Yes. Most of our projects are existing shops that are too slow, rank poorly or have errors. We start with an audit and a fixed-price offer for the most important measures.
What is shop SEO and why is normal SEO not enough?
Shops have their own problems: thousands of product pages, filters that create duplicates, missing product texts, category pages without content, images without alt text. Shop SEO solves exactly these problems systematically, mostly through templates and rules instead of page by page.
Do you also build marketplace integrations?
Yes, for example Amazon, eBay, Kaufland or price comparison sites via feeds and APIs. Likewise integrations with inventory management, payment providers and shipping carriers.
What does a new online shop cost?
It depends on system, scope, integrations and data migration. Before the start we name a fixed price for a clearly described scope and calculate the running costs for hosting, licences and apps with you.
How long does a shop project take?
A relaunch with data migration usually takes two to four months, depending on scope and integrations. A new shop with a manageable catalogue is often online in six to eight weeks. We work in stages that you approve individually.
Can you help us sell into the German market?
Yes. We set up shops for the German market with the legal requirements for checkout, pricing, shipping and returns, German-language SEO and the payment methods German customers expect.
