Methodology: How We Determine the Top 50

At 1stCollab, we continuously track and analyze data from over 100 million creators across TikTok, YouTube, and Instagram. Our rankings are built on these verified content, audience, and performance metrics.

Each influencer is evaluated across three weighted pillars of performance:

1. Reach: Audience size and typical post impressions across major social platforms.

2. Engagement Rate: Interactions per view, adjusted for platform norms.

3. Engagement Quality: Depth and authenticity of interactions, including comments, shares, and saves.

Results are normalized across platforms and time periods to ensure a fair comparison between creators, and our Top 50 lists are updated every week. Data is sourced from a combination of direct data partnerships with the social platforms, public metrics, and a proprietary 1stCollab performance dataset, ensuring consistent, independent analysis.
