How to Write Viral Social Media Captions
Hook in the First Line
The algorithm shows the first 1–2 lines before "more". Your hook must stop the scroll. Use a bold claim, a surprising statistic, or an open-ended question.
Embed Social SEO Keywords
Platforms like TikTok and Instagram index captions for search. Include your niche keywords naturally — not as hashtags, but as part of the caption text.
Hashtag Strategy
Use a mix of broad (1M+ posts), mid-tier (100K–1M), and niche-specific (under 100K) hashtags. Aim for 3–5 well-chosen tags rather than 30 generic ones.
