Recognisability. A consistent name, number and visual template trains your audience to expect and seek out each episode. When people can spot your series in a crowded feed, returning-viewer rates climb — which is exactly what the algorithm rewards.
Never judge a series on one post. Publish three episodes, then compare retention and saves. If they rise, keep going; if they fall each time, change the format (length, hook, structure) rather than abandoning the concept.
Pick a cadence you can sustain for the full run — weekly is the safest for most creators. Consistency of timing matters as much as consistency of format, so your audience knows exactly when the next episode drops.
