Caption writing questions

How do I write a good Instagram caption?

Start with a hook in the first line — that's what shows before 'more'. Use line breaks for readability, include a call to action (comment, save, share), and add relevant hashtags at the end. Keep the tone consistent with your brand.

How long should a LinkedIn post caption be?

LinkedIn posts perform best at 150–300 words. Short enough to read quickly, long enough to provide real value. Always end with a question to encourage comments — LinkedIn's algorithm rewards engagement.

What makes a good TikTok caption?

TikTok captions are secondary to the video, but they still matter. Keep them under 100 characters, use 3–5 relevant hashtags, and include a simple call to action like 'watch till the end' or 'comment your thoughts'.

Should I use the same caption on every platform?

No — each platform has a different audience, tone, and format expectation. What works on LinkedIn (professional, long-form) rarely works on TikTok (casual, punchy). Adapt your core message to each platform's culture.

How often should I post on social media?

Consistency beats frequency. It's better to post 3 times a week reliably than 7 times one week and zero the next. Instagram: 3–5x/week. LinkedIn: 2–3x/week. X/Twitter: 1–3x/day. TikTok: 1–2x/day for growth.
