A good caption hooks attention in the first line, adds context or emotion, and ends with a call-to-action or question to drive engagement.
How long should captions be? ▸
It depends on the platform. Instagram allows up to 2,200 characters but engagement peaks at 138-150. TikTok captions should stay under 150 characters. Twitter has a 280-character limit.

On Instagram and TikTok, yes — 3-5 relevant hashtags help discoverability. On LinkedIn, 2-3 is enough. On Twitter/X, hashtags matter less for reach.
