When evaluating social media influencers for SEO collaborations, you should consider the following metrics: Relevance: Make sure the influencer is relevant to your brand and industry. Audience demographics: Look at the influencer's audience demographics to ensure they align with your target audience. Engagement rate: Check the influencer's engagement rate to see if their followers are actively engaging with their content. Follower count: While a high follower count is desirable, it's not the only metric to consider. Ensure the influencer's followers are authentic and not bought. Brand affinity: Look at the influencer's past partnerships to see if they align with your brand's values.
