PR Index
The PR Index is a publicity evaluation model developed by NEWTON Media. It provides an integrated overview of communication performance. It combines quantitative and qualitative indicators, with the qualitative criteria assessed in context rather than by keywords alone. It takes into account the specifics of individual industries and enables comparison with competitors.
The index can be tailored to individual communication objectives and is measured in real time. It also allows for an ambivalent category, which is particularly important when evaluating crisis communication.

Additions, clarifications, extended definition
It is a qualitative parameter that measures the effectiveness of media communication about a brand. It takes into account the quality of the media in which the information was published as well as the quality of the individual items (stories).
It makes it possible to track communication performance over time, compare performance across the market – between a client and its key competitors – and compare performance between brands with different levels of media presence.
Interpretation
Performance is expressed as a number on a scale from -100 to +100, indicating the overall quality of media coverage.
A higher positive score (+20 and above) – the green segment – indicates that communication objectives are being met successfully, meaning a predominance of top-quality items with positive sentiment and high reach among the target population.
A lower positive score (up to +20) – the yellow segment – means that the coverage is starting to be dominated by lower-quality, typically neutral items with lower reach – more marginal mentions or items containing fewer key messages.
A negative score – the red segment – always signals negative sentiment; an average negative value would mean such items predominate in the overall coverage.
The resulting PR Index value therefore works like a traffic light, showing whether the coverage has drifted into undesirable territory (red), whether more effort is needed (yellow), or whether communication is riding a favourable "green wave".
Watch out: limits and risks of distortion
- The PR Index is a customised metric targeted at a specific company / brand / event.
- The quality of the resulting score increases with the precision of the specification of the individual parameters the index is built from.
- If the client knows exactly what they require when measuring sentiment, the extent of the information, reach in significant media (tiering) and key message content, the result is a highly accurate assessment of the quality of their communication as well as a comparison with competitors' communication (benchmarking).
- Conversely, a brief that is too general and poorly targeted can lead to less accurate results.
Where and how to measure
- The PR Index is an integrated part of the NewtonOne NG platform, where it is calculated in real time for all monitored items.
Context
The PR Index complements and replaces previously used metrics, which typically measure only one dimension of media coverage, with a single aggregate number on a closed scale, making it easy to compare results over time and across markets.
It was designed to fully comply with the Barcelona Principles of communication measurement.
Formulas
PRI = context × (importance + visibility)
Example from practice
A strong global brand faces a local competitor in a local market that manages to achieve comparable results in terms of communication quality with a much lower communication budget and fewer media items. The PR Index makes it possible to measure the communication outputs of such different competitors in real time across several dimensions at once and to compare their quality on the same scale.
