What is engagement rate?

Engagement rate (ER) is the percentage of an audience that actively interacted with a piece of content. It is calculated by dividing total engagements (likes, comments, shares, saves) by a baseline — reach, followers, or impressions — then multiplying by 100.

Which engagement rate formula should I use?

ER by Reach is the most accurate for a single post because it measures interactions against the people who actually saw it. ER by Followers is most common for comparing accounts over time. ER by Impressions is used when a post is shown multiple times to the same person (e.g., paid media).

What is a good engagement rate on Instagram?

For Instagram, 3–6% by reach is considered good for organic posts. By followers, 1–3% is a healthy benchmark. Rates above 6% by reach are excellent; below 1% by followers suggests low resonance.

What is a good engagement rate on TikTok?

TikTok measures ER by views (equivalent to reach). A rate of 4–18% is typical for organic content. TikTok's algorithm-driven distribution means ER can vary widely between posts on the same account.

What is a good engagement rate on LinkedIn?

LinkedIn ER by impressions of 2–5% is considered good. LinkedIn tends to have lower engagement volumes than Instagram or TikTok, but interactions carry higher professional intent.

Why do reach and follower ER give different numbers?

Reach is always a subset of followers — not all followers see every post. If your reach is 30% of your follower count, your ER by reach will be roughly 3x higher than ER by followers for the same engagement count. Both metrics are valid but serve different analytical purposes.
