As much as 70 per cent of marketers in India admit that they find it difficult to integrate data from different sources, says the study by global market insight firm TNS.
Indian businesses are investing more in data-driven digital platforms and tracking systems to help them understand the challenging online landscape, it added.
"With so much data available, marketers know they should be able to make decisions in real-time, but many are struggling to integrate traditional and digital measurements," the report said.
"Yet, 70 per cent are unable to integrate multiple data sources -- such as social media, blogs, website traffic and search data -- leaving them unsure what action to take," it added.

"India's online environment is developing at break-neck speed. As more and more people start connecting to the Internet through mobile and accessing digital platforms, the amount of data is set to explode. The key is to understand how to use it effectively now, before the volume becomes unmanageable," Visvanathan said.
Due to the difficulties with real-time data, many marketers are falling back on traditional measurements, the survey said, adding that sales uplift metrics were still used as the number one way of evaluating the success of marketing campaigns.
TNS Marketing Monitor was carried out in eight markets in Asia Pacific, including India, China and Australia and is based on responses from 2,716 marketing professionals across markets, the company said.
