Nissan-Renault is outsourcing the management and user-experience optimisation of its 300 global websites to AppDynamics.
The carmaker, which is in the midst of an international rollout of its desktop and mobile sites, is anticipated to receive 4.5 billion views a year.
It will use the AppDynamics Intelligence Platform to monitor performance, user-experience and infrastructure analytics for DigitasLBi, the marketing agency for the Renault-Nissan Alliance.
By monitoring demand the IT department can scale infrastructure where needed and optimise the design of the site by analysing where customers are clicking.
The websites, which include the new My Renault online portal, will be hosted by DigitasLBi.
Renault is due to finish its global rollout of Salesforce this month.
The deployment is part of its digital and CRM strategy, a channel that makes up 10 percent of the carmakers sales.
It plans to "leverage data for a better service" by rationalising its regional systems, its director for call centres and CRM said during Salesforce's Dreamforce conference in San Francisco last year.
The CRM project includes merging 34 countries' marketing tools, 5,000 dealer management users, sales performance, 10,000 call centre seats and its 'My Renault' digital customer portal systems into a centralised Salesforce platform by March 2015, Laporte said.
Laparte said that he hoped the project would convert its 10 million annual leads into sales.
The Renault-Nissan Alliance, created in 1999, is the longest-running merger of two leading carmakers.
