Postr IndexSM reframes creator sponsorship pricing as a market surface. Each series tracks the average payout price for a single sponsored social media post of a specific post type.
Prices are quoted per post. The index reflects the average payout a sponsor would expect to pay for one post within a given platform, post type (format), and size-class.
The landing explorer shows the composite series for each supported site. Each platform card plots every supported post type together so you can compare format-level pricing behavior within one network.
Detail pages let you move from those broader composites into more specific slices like creator tier, then switch between high-average-low bands, single-series lines, and candlesticks.
The y-axis represents payout price per post. The goal is to show how pricing shifts across platforms and post formats rather than normalize everything to an impression-based unit.
