LinkedIn has revealed that a pair of measurement issues which it discovered may have led to overreporting of some impression and video views metrics.

The career-focused social network’s engineering team found the two measurement errors, which have since been fixed, back in August. The issues meant that some sponsored content campaign metrics for impression and video views may have been overreported, affecting more than 418,000 of LinkedIn’s customers over a period of more than two years.

According to LinkedIn’s Vice President of Product Management, Gyanda Sachdeva, over 90 per cent of customers saw an impact of less than $25. However, LinkedIn is working with all customers to provide full credit to their accounts.

LinkedIn says it has put measures in place to prevent future errors like this, including allowing the Media Rating Council (MRC) to audit the social network’s metrics, a partnership with Moat by Oracle Data Cloud to measure video viewability, and investing in improvements to its processes and systems.

“We are committed to delivering consistent advertising products and analytics that you can rely on and that align with industry and third-party standards,” said Sachdeva. “We’ll plan to share updates on the ongoing work that we’re doing to keep our advertising platform safe and trusted.”
