This document discusses citation analysis and metrics for measuring research impact, including citation count, h-index, and altmetrics. It explains that citation analysis tools measure how often a researcher's published work has been cited by others, and that citation count and h-index are commonly used metrics. However, it notes limitations in relying on any single tool or metric and cautions that interpretation depends on factors like discipline and time publishing. The document encourages researchers to use multiple tools and social media to increase their visibility and influence.
