What “engagement rate” means here

What is engagement rate on a single post?

A post’s engagement rate is how much interaction it got, like likes, comments, and shares, relative to how many times it was seen, shown as a percentage.

Karrow doesn’t work this number out itself. Each post’s rate is reported by the platform and collected by Karrow’s publishing partner, and Karrow shows it exactly as reported. Which interactions count, and how views are counted, is the platform’s own definition.

The rate already arrives as a percentage, and Karrow shows it to one decimal place. A reported 2.78 appears as 2.8%; Karrow never multiplies or rescales it.

Where you’ll see it

Engagement rate shows up in five places: the Eng. rate column of the Channels table on the Analytics page, the Engagement rate over time chart, each row of Top posts (as “eng.”), a post’s drawer when you click it, and the summary line of the Dashboard’s Channels Performance card.

Everywhere it appears, a dash (—) means no rate has been reported yet. That is different from 0.0%, which means a rate was reported and it was zero.

How is engagement rate calculated for a channel?

For a channel, Karrow averages its posts’ rates for the period, weighting each post by its impressions. A post seen by 10,000 people counts for far more than one seen by 100.

A hypothetical example: Post A had 10,000 impressions at 2.0%, and Post B had 100 impressions at 12.0%. A plain average would say 7.0%. The weighted rate is (10,000 × 2.0 + 100 × 12.0) ÷ 10,100, which is about 2.1%. That is much closer to what most of your audience did.

Only posts that went out through Karrow in the period, and that have a rate reported, are included. If none of a channel’s posts report impressions, Karrow falls back to a plain average of their rates.

Across all your channels

The Dashboard’s Channels Performance card shows one engagement rate for all your channels over the last 30 days. It combines each channel’s rate the same way, weighted by that channel’s impressions, so a channel with a few dozen views can’t swing the overall number.

Pick one platform in that card’s strip to see its own rate instead.

Why does my engagement rate arrow show 25% when the rate barely moved?

The arrow shows the percentage change in the rate itself, not the difference in percentage points.

A hypothetical example: a channel at 2.0% last period and 2.5% this period shows an up arrow with +25.0%, because 2.5 is a quarter higher than 2.0. Going from 2.0% to 1.5% shows a down arrow with -25.0%.

The previous period is the same length, right before the current one, and posts are grouped by the day they were published. If the earlier period had no posts with a rate, there is no arrow.

Reading the engagement rate chart

Engagement rate over time on the Analytics page draws one dot per post, at that post’s own rate on the day it went out. It isn’t a daily average, so the line between two dots joins two posts rather than tracing the days in between.

The chart appears once the period has at least two posts with a rate, and it follows the publication, channel, and period filters at the top of the page.

Hover over a dot to see the date the post went out and its rate. With All channels selected, dots from different platforms share one line, so filter to one channel before you read a trend into it.

Can I compare engagement rate between LinkedIn and X?

Only loosely, because each platform counts views and interactions its own way, so the same rate can mean different things on LinkedIn and X.

The rate is most useful for comparing a channel with itself over time, or one post with another on the same channel. Use the channel filter on the Analytics page to look at one platform at a time.

LinkedIn doesn’t report saves or clicks to Karrow, and Reddit doesn’t report anything, so Reddit has no engagement rate at all.

When a rate can mislead

A post seen by very few people can show a high rate from a handful of reactions. Before you read much into a rate, check the impressions beside it.

Short periods have few posts. In the 7d view, a channel’s rate may rest on one or two posts, so one unusual post moves it a lot. The 30d and 90d views give a steadier figure.

A new post’s rate can move for a while. Karrow keeps updating a post’s numbers for about 45 days after it goes out, so judge recent posts after a few days, not on the first morning.

Engagement rate measures attention on the platform. If you post to bring readers to your newsletter, look at Clicks as well, on the channels that report them.

A rising rate on a channel is a good sign, not a promise. Reach on every platform varies from post to post, so look for a direction over several weeks rather than reacting to one post.
