Reach and engagement are the two most-used words in influencer marketing. They are also the most frequently confused. Brands often treat them as interchangeable when they measure fundamentally different things — and optimising for the wrong one leads to campaigns that look good on paper but deliver poor business results. This page explains what each metric actually measures, when each one matters, and how anchors separates them in campaign reporting so you can make informed decisions.Documentation Index

The core difference
Reach
The number of unique LinkedIn members who saw a creator’s post at least once. Reach is a visibility metric. It answers: how many different people were exposed to your message?
Engagement
The total actions taken on a post — likes, comments, and reposts. Engagement is a response metric. It answers: how many people did something after seeing your message?
Reach counts unique people. Impressions count total displays — the same person seeing a post three times adds three impressions but only one to reach. When comparing campaign results, reach is the more accurate visibility number.
What each metric tells you
What reach tells you
Reach tells you the size of your potential audience exposure. If a campaign reaches 80,000 unique LinkedIn professionals and your ICP is mid-level marketing managers in India, reach answers whether those 80,000 people include the right segment — not whether they responded. Reach on its own does not tell you:- Whether the right people saw it (audience fit matters here)
- Whether anyone cared (engagement tells you this)
- Whether it changed behaviour (conversion data tells you this)
What engagement tells you
Engagement — and especially comments — tells you that someone cared enough to respond. On LinkedIn, commenting takes more effort than liking. A comment is a much stronger signal than a like. Within engagement, not all actions carry equal weight:| Action | Signal strength | What it indicates |
|---|---|---|
| Repost | High | Audience found it valuable enough to share with their own network |
| Comment | High | Audience had a reaction strong enough to write it down |
| Like | Medium | Audience acknowledged the content |
- Whether the engagements came from your target audience
- Whether the volume is proportional to the creator’s reach (engagement rate matters here)
- Whether the engagement was positive (sentiment analysis in the AI Analysis Report tells you this)
Engagement rate — the metric that connects both
Engagement rate (ER) is the ratio of engagement to audience size. It gives context to raw engagement numbers.Which metric to optimise for
- Optimise for Reach
- Optimise for Engagement
- Balanced campaigns
Choose reach as your primary metric when:
- The campaign goal is awareness — getting your brand name in front of as many relevant professionals as possible
- You are entering a new market or category where very few people know you exist
- You are running a product launch and want maximum day-one visibility
- Your ICP is broad — you are targeting a large professional segment rather than a hyper-specific niche
How anchors separates reach and engagement in reporting
anchors tracks both metrics independently across every campaign and surfaces them at the creator level, not just in aggregate. In the AI Analysis Report, you will see:| Report section | What it shows |
|---|---|
| Reached Audience | Total unique viewers, broken down by role, industry, seniority, and location |
| Engaged Audience | The subset who liked, commented, or reposted, with the same demographic breakdown |
| Engagement rate per creator | ER calculated individually per creator so you can compare response quality across your creator mix |
| Sentiment per creator | Whether the engagement was positive, negative, or neutral — because a high comment count with negative sentiment is not a campaign win |
The gap between reached audience and engaged audience tells you something important. A very large gap — say, 90,000 reached and 400 engaged — is normal at higher tiers and for awareness campaigns. A smaller gap proportionally — 8,000 reached and 600 engaged — signals strong resonance and is typical of well-matched Micro creators.
A quick decision framework
Before launching any campaign on anchors, answer these two questions: 1. What does success look like for this campaign? If the answer is about visibility and brand name recognition, optimise for reach. If the answer is about audience response, conversation quality, or downstream conversion, optimise for engagement. 2. How will you measure it? Define your benchmark before the campaign goes live. A reach-focused campaign should have a target unique viewer number. An engagement-focused campaign should have a target comment count or engagement rate floor.Related pages
