Make Carousels the Primary Test
Random Sam's Instagram engagement rate is 0.04%, with posts at 0.06% and Reels at 0.02%, so carousels should be the default format for upcoming feed content.
Details
The 0.55% carousel benchmark exceeds both the 0.06% post ER and 0.02% Reel ER; use a clear promise on slide 1, one idea per slide, and a question on the final slide.
