The Attention Index

Kaleida's Attention Index is an open standard for measuring premium media.

The algorithm combines data about what professional media orgs value with what consumers of media value. The scoring system surfaces high impact media and data which can be used to support healthier economics across the media ecosystem. The data, algorithm and methodology are publicly available with a Creative Commons license.

The media ecosystem has been defined by reach, impressions, and clicks for about 20 years. But those measures of success don't translate into business models that work for most media orgs.

It seems counterintuitive that media orgs would struggle given the massive opportunity the Internet offers. Ad spending in digital is expected to reach $224 billion globally in 2017. If they could demonstrate how much impact they have in the world then new, better business models might find quality journalism outlets and fuel a lucrative position for them in the media ecosystem.

At Kaleida we think it all starts by looking at professional media and consumers as equal contributors to one conversation. That was the starting point for the Attention Index.

How and what

Publisher data and social data are combined to arrive at an overall Attention Score. We obtain this data using a range of tools to process the data including our own homegrown applications and 3rd party data processing services.


  • We've published our work in a python jupyter notebook. That document goes step-by-step through our data explorations detailing how we arrived at these results. It includes the exploratory analysis, charts, data tables, statistics and the resulting formulas.
  • You are encouraged to apply our approach to developing the Attention Index. The methodology provides detail about what the data means, how it was collected and what we're doing with it.
