In more detail
A share spreads your content beyond the people who already follow you, which is how posts reach new audiences and sometimes go viral. Because sharing takes more effort and social risk than a like or comment, platforms usually weight it heavily in their ranking algorithms. The exact label varies: it is a repost on X, a share on Facebook and LinkedIn, and a send or share-to-story on Instagram and TikTok. Tracking shares tells you which content people find worth passing along, not just worth glancing at.
Example
If a post gets 500 likes but only 3 shares, people enjoyed it but did not feel it was worth showing their own followers. A post with 50 shares, even on fewer likes, is doing real work to grow your reach.
