The next step is to select the metrics that will help you measure the impact of publicity on thought leadership. Metrics are the indicators that show how well you are performing against your goals and objectives. There are different types of metrics that you can use, such as output, outcome, and impact metrics. Output metrics measure the quantity and quality of your publicity activities, such as the number of media mentions, the reach and engagement of your content, and the sentiment and tone of your coverage. Outcome metrics measure the changes in awareness, perception, and behavior of your target audience, such as the increase in brand recognition, reputation, and trust, the generation of leads and referrals, and the conversion of prospects into customers. Impact metrics measure the long-term effects and value of your publicity on thought leadership, such as the growth in revenue, market share, and social impact, the influence on policy and decision-making, and the contribution to innovation and knowledge.
