Once you have your SMART objectives, you need to choose the appropriate metrics that will help you to track and evaluate your PR performance. Metrics are the indicators that measure the outputs, outcomes, and impacts of your PR activities. Outputs are the tangible results of your PR actions, such as media coverage, social media posts, or events. Outcomes are the changes in attitudes, opinions, or behaviors of your stakeholders as a result of your PR activities, such as awareness, perception, or engagement. Impacts are the long-term effects of your PR activities on your organization's goals, such as sales, reputation, or loyalty. Depending on your objectives, you may use different metrics to measure your outputs, outcomes, and impacts. For example, some common metrics for PR are: reach, impressions, share of voice, sentiment, conversions, or return on investment.
