Every fast changing industry has its jargon.

The lexicon emerges to aid efficient communication, but that efficiency is only achieved when everyone knows what the words and phrases really mean, and uses them consistently.

This glossary aims to help secure that consistency sooner than otherwise.

Barcelona Principles

A series of statements to guide best practice in PR measurement that were endorsed after a vote of global delegates at the AMEC European Measurement Summit in 2010:

  • Goal setting and measurement are fundamental aspects of any PR programmes.
  • Media measurement requires quantity and quality – cuttings in themselves are not enough.
  • Advertising Value Equivalents (AVEs) do not measure the value of PR and do not inform future activity.
  • Social media can and should be measured. Measuring outcomes is preferred to measuring media results.
  • Business results can and should be measured where possible.
  • Transparency and Replicability are paramount to sound measurement


A series of content, typically text or image, published on a web page in sequential date order focused on a subject or issue and encouraging interaction. Also see vlog.


A software application that runs automated tasks over the Internet. Typically, bots perform tasks that are both simple and structurally repetitive, at a much higher rate than would be possible for a human alone.

Bounce rate

A ‘bounce’ is when a visitor to a website only views a single page before leaving. Bounce rate is the percentage of visits to a webpage where this occurs. A high bounce rate indicates a lack of engagement.

A copy of a document or other digital file is pulled from a web server to the user’s Internet connected device. When a user accesses a web page, it’s actually downloaded from a web server to the user’s browser, but this isn’t usually what’s meant when the word is invoked.


Earned media

Third-party media coverage secured through a relationship or news worthy event, rather than paid-for advertising or other means of securing media. Includes on- and off-line media. Often used synonymously with public relations, but public relations is not defined by media.


Occupy or attract someone’s interest or attention; involve someone in a conversation or discussion.

Commonly used when analysing how much visual presence and ‘wow factor’ a piece of content carries.

You have been influenced when you think in a way you wouldn’t otherwise have thought or do something you wouldn’t otherwise have done. There is currently no scalable facility to ascertain or infer who or what caused someone to change their mind or behaviour. Metrics often presented as measuring influence (eg. Klout) do not measure influence, rather the propensity for an individual’s social media contributions to be shared, and the reach of that sharing, and this idea is increasingly being rechristened social capital.


The Institute for Public Relations, a US based independent non-profit foundation dedicated to the science beneath the art of public relations.


A matter, typically in dispute, between two or more interested parties.




A well-known service that purports to measure influence.


Key performance indicator(s); define a set of values against which to measure success. KPIs must be defined to reflect objectives and strategy, and will be sufficiently robust for the measurement to be repeatable. Quantitative KPIs can be presented as a number, ratio or percentage. KPI’s tend to be:

  • Quantitative indicators which can be presented as a number
  • Practical indicators that interface with existing company processes
  • Directional indicators specifying whether organisational performance is improving or not
  • Actionable indicators sufficiently in an organisation’s control to effect change
  • Financial indicators used in performance measurement and when looking at an operating index.

A dis-aggregated number of people (or percentage of an audience) that have been exposed to content. ‘Reach’ differs from impressions, opportunities to see and eyeballs in that it counts the actual number of people exposed to coverage rather than the number of ‘opportunities’ to see the coverage. It is a widely mis-used term in the industry and should only be used when readership data has been dis-aggregated to take account of cross readership patterns.

Reach and Frequency

A common metric quantifying campaign success predominantly used and accepted in advertising. It couples the reach metric with frequency which is the average number of times that each person has been reached, or exposed, to the content.
