Insights on e-commerce, web development and digital solutions
Here you find our articles about online shops, websites and web tech. We explain new rules, tools and good ways of working. You can filter the articles by topic. At the top of an article you find a short version in plain words. Ask us if something is still not clear.
Customer prices belong behind the login, the product page does not. How wholesale shops keep their range public for search engines, which structured data is allowed without a price, why paywall markup is no way out and how the German Price Indication Ordinance fits in.
Three language versions add up to nine annotations, and one missing entry makes the pair ineffective. How the annotation is built, which codes are valid, what x-default does and where automatic redirects meet a legal limit.
31 percent buy from the next supplier when an item is missing. Which states a shop has to tell apart, which markup belongs to each, and when 410 fits better than 404.
Which address a crawler requested, with which status code and how many bytes: that lives only in the access log. How a shop evaluates it and what the network-wide figures say.
Without a redirect plan, one documented relaunch cost 42 percent of organic traffic within twelve days. This guide walks through the redirect matrix, status codes, testing and follow-up step by step.
AI Overviews appear on 20.5 percent of all search result pages but on only 3.2 percent of shopping searches – the leverage sits with the guide searches that come before the purchase. This guide shows how to prepare product pages with clean data, valid structured data and citable guide content for Google's AI answers and make the visibility measurable.
A product in six colors and five sizes quickly becomes 30 nearly identical URLs for search engines that dilute the product page's ranking value. How to consolidate product variants with a canonical master URL, correct canonical tags and clean internal linking – and why this is a different problem from filter and facet URLs.
Text and data mining is permitted unless a machine-readable reservation exists. How shops declare the TDM opt-out in three places – without accidentally blocking retrieval crawlers too.
Filter and sort URLs turn a few thousand products into millions of pages – Google names faceted navigation as the single largest cause of crawling problems. A decision matrix instead of guesswork: which facets deserve a landing page, which belong out of the crawl, and why robots.txt and noindex are not interchangeable.

Our anonymous reach measurement runs without cookies and without IP storage, including campaign parameters in links – we do not ask for consent for it because none is legally required.
Strictly required: language preference, core site functions and storing your cookie choice. Without these the site does not work. Settings you choose yourself (light/dark appearance, accessibility) are kept in your browser's local storage only once you choose them; "Reset" in the accessibility settings removes them.
Records your interactions (clicks, scrolling, inputs) pseudonymously so we can spot usability issues. Form field inputs are masked automatically before storage; your IP address is not saved with the recording. Served from our own domain, no external tool. Opt-in, revocable any time.
