In the context of journal impact scores, what is an indicator of a high-impact journal?

A score of 20 and above is considered an indicator of a high-impact journal because it reflects the level of influence and the frequency with which articles in that journal are cited. High-impact journals typically publish research that is not only original and significant but also widely recognized and referenced in the field. The higher the impact score, often measured through metrics like the Impact Factor, the greater the journal's reputation and the likelihood that published work will reach a broader audience, contributing to the advancement of knowledge in that area. This association with quality, visibility, and citation frequency makes a score of 20 and above a hallmark of high-impact journals, appealing to researchers looking to publish their most significant work in venues that will maximize its reach and influence.
