Reach is an important metric to consider when measuring the success of your influencer marketing campaign, but it is not enough. Reach only tells you how many people saw your influencer's content, not how they reacted to it or what actions they took afterwards. That is why it is essential to measure other metrics that reflect the impact and value of your campaign, such as engagement, brand awareness, brand affinity, and conversions. Engagement measures the number of likes, comments, shares, saves, clicks, views, or reactions that your influencer's content receives. Brand awareness looks at the increase in recognition and recall of your brand name, logo, slogan, or product among your target audience. Brand affinity examines the degree of emotional connection and loyalty that your target audience feels towards your brand. Finally, conversions are the number of leads, sales, sign-ups, downloads, or referrals that your influencer's content generates.
