Consumers are increasingly relying on comparison tools (websites, apps) to compare products and services according to their prices, quality or any other parameter. This is why in 2012 the European Commission started to work with stakeholders to address the reliability and transparency of these tools (for details see background).

One of the key deliverables of this work was a market study mapping comparison tools in the EU and looking at how they were used by consumers. The study was finalised at the end of 2014.
