A macro-influencer is an influencer with roughly 500,000 to 1 million followers. This tier sits between mid-tier influencers and mega-influencers, offering wide visibility, usually at a proportionally higher cost than smaller creators.

The 500,000–1 million range is a general convention rather than an official standard, and the exact cutoffs vary by platform and industry. Macro-influencers are large enough that many work with talent managers or agencies to handle brand deals, rather than negotiating every partnership directly.

Compared to mid-tier influencers (roughly 50,000–500,000 followers), macro-influencers reach more people per post but typically see lower engagement rates, since their audience is broader and less tightly connected around a single topic. Compared to mega-influencers (1 million-plus followers), they're usually still associated with a recognizable niche rather than mainstream celebrity status.

Macro-influencers work well for campaigns that need broad visibility fast, a product launch or a limited-time promotion where reaching a large audience in a short window matters more than the tighter community feel of a smaller creator's following. They're also often more experienced at producing polished, brand-ready content, having worked with multiple sponsors before.
