Make Feed Posts the Baseline
Instagram posts for Grand Slam Track average 1.32% ER versus 1.01% for Reels, so feed posts should serve as the engagement baseline and carousel-led posts should be tested before increasing Reel volume.

The 2026 format benchmarks place carousels at 0.55% ER, ahead of Reels at 0.52% and static images at 0.45%; each carousel's ER should be compared with the 1.32% post baseline.
