About RAR research

RAR gathers information from companies across the spectrum of marketing services, with details of key clients, resources and key staff, sector experience, case histories and company finances all captured.

Uniquely, we also measure a company's level of customer satisfaction, asking clients to rate their suppliers in two ways:  First, we ask them to give a score out of 100 for each service they have bought from the agency.  Second, we ask them give a score out of 100 for seven key criteria:

  1. Client service
  2. Creativity/innovation
  3. Effectiveness
  4. Strategic thinking
  5. Value for money
  6. On Time
  7. On Budget

Suppliers must have a minimum of three high ratings per service before being recommended and we also welcome comments on service levels, key individuals and any specific work of note. All input is confidential and comments are never attributed. The ratings for these criteria are combined, and using the forumula described below provide an overall score. The individual ratings act as an independent measure of agency performance.

Only companies who score above our threshold become recommended and are included in the register. The results provide a unique insight into the experiences of other clients with particular suppliers.

Clients can visit our site and rate their current suppliers at any time. Or marketing suppliers themselves can register and invite their clients to rate their service. Any individual client ratings or commentary are never attributed and this process is completely confidential.

Service details

We believe that customers are the best judge of any product or service, so suppliers are recommended not for what services they offer, but for the services clients recommend in the research. This ensures that we highlight the true key strengths for each supplier. For instance, a supplier may offer a range of services such as Advertising, Design, Digital, PR and Direct Marketing. To be recommended for all these services, agencies must receive three ratings above our threshold for each service.

How We Rate Suppliers

Supplier ratings are not currently visible on the website but are available through requested reports. Suppliers can see their own rating results in their site admin area. Ratings are derived from the research carried out on an ongoing basis.

The formula for calculating the overall RAR ratings gives a true Bayesian estimate:

Weighted rating (WR) = (v ÷ (v+m)) x R + (m ÷ (v+m)) x CR = average for the supplier (mean) v = number of votes for the supplierm = minimum votes required to be recommended (currently 3) C = the mean vote across the whole research (currently set at 68)
