Merits of Impact factor
In market research, Impact Factor provides quantitative evidence for editors and publishers for positioning their journals in relation to the competition—especially others in the same subject category.
It provides quantitative tools for ranking, evaluating, categorizing and comparing journals.
It eliminates some of the bias of such counts which favour large journals over small ones or frequently issued journals over less frequently issued ones and of older journals over newer ones. Particularly in the latter case such journals have a larger citable body of literature than smaller or younger journals.
It may also serve to advertisers interested in evaluating the potential of a specific journal.
The Impact Factor is being used to provide a gross approximation of the prestige of journals in which individuals have been published.
