Market information service Nielsen has signed a deal with price monitoring firm Profitero.

Profitero will provide online competitor price monitoring which Nielsen will offer alongside its own market information to retailers in more than 20 countries.

The price information will be at national and regional level including competitors’ regular and promotional prices, promotions types, messages and product assortment.

The move will allow Nielsen, known for its grocery market share data and Shop Price Index services, to allow retailers to benchmark pricing and promotions.

Profitero monitors more than 40 million products across 3,500 websites daily and its clients include Tesco, Ocado and Walmart.

Profitero co-founder and chief executive Volodymyr Pigrukh said: “We are delighted to team with Nielsen to provide its hundreds of retail clients with online competitor pricing intelligence data.

“With the majority of retailers now selling on the internet, such online competitor pricing data is essential for multichannel retailers to grow sales and increase market share.”
