Each case comes with its dates and what else changed

How to read these cases

• A case study shows what happened on one website over a stated period. That result does not predict what will happen on your website, because every site begins with different content, traffic and history.
• We take scan results ourselves and can show the method. Traffic figures come from the site owner's analytics, and we report them with their dates. We publish a case only with the owner's consent.
• Traffic moves for many reasons, such as the season, prices, ads and new products. When other changes happened in the same months, the case page lists them, and we do not credit the whole change to our work.
• Before we call anything a result, each case states the dates, the measure we used and how we defined the outcome.
