Start with the page closest to the decision you need to make. A brand that also runs its own shop can use both the Brands and the Retailers page. The data underneath is the same, and only the questions change.

ECDB models e-commerce revenue from a range of inputs, including transaction data, company reports and web signals. Every market, category and store runs through the same method. That makes a figure for Poland directly comparable with one for Spain.

ECDB's analysts model every market and store from researched, harmonized data, with card transaction data as the core input. More than 1 billion online and offline transactions run through the model every month. Each estimate is checked against figures published by stock-listed companies, which keeps improving the model over time. Every market and retailer also carries a Quality Indicator of A, B or C, so you can see how much data and analyst work sits behind each figure.

Market and retailer data are updated every month. Transaction data arrives about seven days after the purchase and is processed right away. When major events or new figures change a market, ECDB updates it ad hoc between cycles. Last year's figures firm up over the first months of the new year as more inputs come in, and past years are refined whenever the model improves.

ECDB covers the full field. A store is defined by its URL, so every domain gets its own figures, including small specialists and regional shops. A single category ranking can list thousands of stores, for example more than 3,000 in German fashion. Smaller stores are modeled with the ECDB Revenue Estimation Model, and their Quality Indicator shows the data depth behind each estimate.

Yes. The six pages show the roles we hear from most often, but the same data serves many others. Payment providers use it to see which PSPs merchants rely on in each market. E-commerce software companies find stores by the shop system they run on. Media, research and public sector teams use it to size and track online markets. Book a demo and tell us what you work on, and we'll show you the views that fit your questions.
