Share Rate
Also known as: shares, send rate
Definition
Share rate is the percentage of viewers who send a post to someone else via DM, story, or external link — the second-strongest engagement signal after saves.
Sharing is endorsement. When a user sends your post to a friend, they are putting their personal credibility behind it. The algorithm understands this and treats shares as one of the highest-quality engagement signals — second only to saves on Instagram and tied for first on TikTok.
Share rate is calculated the same way as save rate: shares divided by reach, times 100. Healthy is 0.5%+, great is 1.5%+, viral is 3%+. There are two share types worth tracking separately: shares to Stories (an Instagram-specific signal that boosts feed reach) and shares to DMs (the strongest peer-endorsement signal and the largest contributor to dark social).
The content patterns that get shared most fall into a few buckets: relatable (a meme that captures a feeling), useful (a framework someone wants to send a colleague), funny (entertainment shared in group chats), and shocking (statistics or contrarian takes). Brands that consistently hit one of those four registers grow much faster than brands stuck in product-promotional posting.
Key Facts
- Shares are tied with saves as the highest-weighted engagement signal on TikTok (TikTok Creator Insights, 2025).
- Average Instagram share rate is 0.3-0.5%; great content shares at 1.5%+.
- Posts shared to Stories drive ~25% additional feed reach over the next 24 hours (Later, 2025).
- Share-driven traffic typically converts 2-3x higher than ad-driven traffic because of the implicit peer endorsement.
Frequently asked questions
What kinds of posts get shared the most?
Relatable (memes, observations), useful (frameworks, lists), funny (entertainment), and shocking (stats, contrarian takes). Promotional posts almost never get shared.
How is share rate calculated?
Shares divided by reach, times 100. Track DM shares and Story shares separately when possible — they signal different things.
Should I ask for shares in my captions?
Yes, when the content genuinely warrants it. 'Send this to a friend who needs to hear it' lifts share rate without coming across as spammy. Avoid asking on every post.

Save Rate
Save rate is the percentage of viewers who bookmark a post for later — a high-weight signal in the Instagram and TikTok algorithms because it indicates the content has lasting value.
Engagement Rate
Engagement rate is the percentage of an audience that interacts with a piece of content — likes, comments, shares, and saves divided by reach or followers.
Dark Social
Dark social is content sharing that happens through private channels — DMs, group chats, email, and screenshots — and cannot be tracked by standard analytics.
