Engagement Rate

In short

Engagement rate shows what percentage of people or impressions interact with a post or ad – through likes, comments, shares, saves or clicks.

Also known as: engagement-rate, interaction rate

Engagement rate measures what percentage of the people who see a post or ad interact with it. Depending on the platform, interactions include likes and other reactions, comments, shares, saves, clicks or video views.

Formula

There is no single definition. Two variants are common:

Engagement rate = interactions ÷ impressions × 100%
Engagement rate = interactions ÷ reach × 100%

Meta, Instagram, TikTok and LinkedIn count different interactions and partly use different bases. Values from different platforms are therefore only comparable to a limited extent.

Example

An Instagram Reel ad gets 40,000 impressions, 900 likes, 120 comments, 80 shares and 100 saves – 1,200 interactions in total.

Engagement rate = 1,200 ÷ 40,000 × 100% = 3%

Engagement rate in lead generation

In organic social media, engagement rate is a central metric because interactions help posts spread. In paid lead campaigns, it is mainly a signal about the creative: does the ad resonate with the audience, does it spark conversation, does it get shared?

But a like is not an inquiry. Entertaining ads often collect lots of interactions without producing leads. Conversely, a plain ad with little engagement may bring in exactly the right prospects. That's why you should always look at engagement rate together with click-through rate, conversion rate and cost per lead.

LeadMetrics syncs spend and daily metrics of your ads and attributes leads and deals from your CRM to them. In dashboards you can compare whether ads with lots of interaction actually lead to closed deals.

Engagement rate vs. click-through rate

Click-through rate only counts clicks, usually on the link to your website or form. Engagement rate combines many kinds of interaction, including ones that don't bring anyone to your page. For lead campaigns, click-through rate is usually the more meaningful of the two.

Common mistakes

  • Optimizing for likes: Lots of reactions don't make a campaign profitable.
  • Mixing definitions: Engagement based on reach comes out higher than engagement based on impressions.
  • Not reading the comments: A high engagement rate can also come from criticism or spam.

Click-Through Rate

Click-through rate (CTR) is the percentage of people who see an ad and then click on it, calculated as clicks divided by impressions.

Reach

Reach is the number of unique people who saw your ad at least once in a given period – each person is counted only once, no matter how often they saw it.

Impressions

Impressions count how often an ad was displayed in total. If the same person sees it several times, every view counts as a separate impression.

Conversion Rate

Conversion rate is the percentage of visitors or leads who complete a desired action, such as submitting a form or making a purchase.

KPI · Key Performance Indicator

A KPI (key performance indicator) is a measurable metric that shows whether you are reaching an important business or marketing goal.

Cost per Acquisition

Cost per acquisition (CPA) measures the average ad spend per conversion such as a purchase or closed deal: ad spend divided by the number of conversions.
