Take care not to use journal-based metrics, such as Journal Impact Factor(s), inappropriately or as a surrogate measure of the quality of individual research articles, to assess an individual scientist’s contributions.
While there is often a relationship between journal ranking metrics and perceived quality, a high number of citations do not necessarily translate into high quality and at the same time the impact of a noted article cannot always be paralleled by the ranking of the journal it is published in.
Journal performance metrics are taken from different sources and are based on a variety of algorithms covering various data-sets. When journals are compared with journals from another field they can vary based on disciplinary/field citation behaviors. This could make it complex to make accurate comparisons.
Below is a list with the main journal indicators used for journals. Use caution when using these indicators as part of grant proposals. Check the grant guidelines first and state clearly the source of the journal indicator included in the proposal.
Take care! The Journal Impact Factor, etc. is applied at the journal-level and provides only a broad indication based on raw data about articles within these journals. It is not an appropriate proxy for researcher/author performance.
