What is "Impact Factor" - and why does that matter?
The phrase "impact factor" is the term used to"measure of the frequency with which the 'average article' in a journal has been cited in a particular year or period." More generally, we use "impact factor" to describe the relative prestige of a journal or a scholar within a field of study.
Where does Google Scholar fit in?
You can use Google Scholar Metrics to view the impact a particular journal has. This is helpful especially when you are evaluating the sources you discover in the research process. Did you find an article, but are unfamiliar with the journal it was published in? Check to see where it ranks in Google Scholar Metrics to get a better understanding of its impact.
So... how does Google Scholar Metrics figure out the impact factor?
Google Scholar Metrics uses a few different indexes to measure the impact factor of journals. It displays a combination of the follow indexes to convey the specific impact factor for a given journal title:
Google Scholar displays the h5-index and the h5-median for each included publication. For more information on their metrics, you can check their page here.
Searching in Metrics:
When you search in Google Scholar Metrics, you will see a list of publications with their corresponding h5 index and h5 median numbers. The higher the index and median value, the higher the impact factor that the given journal title has. See the screenshot below:
