Price monitoring is now standard practice in e-commerce. According to the European Commission (2017), 53% of EU retailers track competitors’ online prices, and two thirds of them use software to do it. Prices move fast: a 2026 PriceRest study found that 46% of online products change price within 30 days. And pricing pays: McKinsey estimates that a 1% price increase raises operating profit by 8.7% when volume holds. Every statistic on this page links to its original source.

Fact check
Popular statistics we excluded
Not every pricing statistic online has a source. We checked each figure on this page on its original publisher’s page. These widely repeated numbers did not pass:
- Amazon changes prices 2.5 million times a day. The figure comes from a 2013 vendor press release that is no longer online, and its method was never published.
- A 1% price rise increases profit by 11%. Often credited to McKinsey, but we could not verify it on any freely accessible primary source. The McKinsey figures we could verify are 8% (2003) and 8.7% (2014).
- 56% of US shoppers start product searches on Amazon. We could not find this exact figure in the original publisher’s reports.
- Retailers spend 10 hours a week checking competitor prices by hand. The original 2019 vendor survey page is no longer available.
