What’s the value of an impression?

Marketers love to talk about impressions. The bigger the number, the more successful a campaign appears. But not all impressions are created equal. The way a consumer encounters your brand and more importantly, who delivers that message  radically shapes its impact.

A paid ad from a macro influencer with millions of followers might deliver a large reach, but does that impression truly land? Compare it with a post from a nano or micro influencer – someone with a smaller but engaged community who feels like a trusted peer and you begin to see why the value of an impression isn’t about volume, but about connection.

Reach vs. Resonance

Macro influencers can deliver huge reach. A single post from someone with 1–2M followers can generate hundreds of thousands of impressions. But reach doesn’t equal resonance.

Macro influencers (500k+ followers): average engagement rates hover around 1.3% (HypeAuditor 2024).

Micro influencers (10k–100k followers): engagement averages 3.5%–4%.

Nano influencers (<10k followers): engagement rates can reach 6–9%, sometimes higher in niche categories.

In other words: more people might see the macro post, but fewer stop to engage. For brands, that means many impressions are passive, not active.

Trust is the Currency

According to Nielsen, 92% of consumers trust recommendations from people they know over all other forms of advertising. Micro and nano influencers live closer to this “trusted peer” category. They’re seen as authentic voices rather than polished endorsers.

A 2024 Edelman Trust Barometer report showed that 61% of consumers trust “a person like me” compared with just 31% who trust celebrities. That difference is why impressions from smaller creators land harder: they’re not just noticed, they’re believed.

Cost Efficiency and ROI

The economics also favour micro and nano influencers.

A macro influencer post can cost anywhere from £20,000-£100,000+ depending on category and reach.

A nano influencer may work with gifted product or a modest fee of £100-£500 per post.

For the same budget as one macro partnership, a brand could activate 100+ nano influencers  generating thousands of pieces of content and reaching highly engaged communities.

Crucially, ROI studies show that nano influencers deliver 2x higher engagement and 60% lower cost per engagement than macro creators (Influencer Marketing Hub, 2023). That means the value of each impression is multiplied.

Peer-to-Peer > Paid Celebrity

Think about your own habits. When was the last time you bought something because a household-name influencer pushed it? Now compare that with the moment a colleague, friend, or a favourite niche creator you follow shared their genuine enthusiasm for a product.

That’s the peer-to-peer power of nano and micro creators. Their impressions feel like recommendations. And recommendations drive action: 74% of people say word-of-mouth is the key driver behind purchase decisions (Ogilvy, 2023).

Beyond the Impression

Marketers often stop at counting impressions. But the real value lies in what comes after:

Engagement: Nano and micro content sparks comments, saves, and conversations.

Consideration: Followers click through, research, and trial.

Conversion: Trusted recommendations shorten the path to purchase.

Advocacy: Many creators continue sharing beyond the campaign if they genuinely love the product.

This multiplier effect means a single impression from a trusted peer can ripple into lasting brand advocacy, something a one-off macro post struggles to deliver.

Rethinking “Value”

It’s time to move beyond the raw numbers. Instead of asking, how many impressions did we get? brands should ask:

Did these impressions generate trust?

Did they inspire action?

Did they contribute to loyalty and long-term growth?

When measured this way, impressions from micro and nano influencers clearly deliver higher value. They may not have the glamour of millions of eyeballs at once, but they deliver what matters most: authentic connections that drive behaviour.

The value of an impression isn’t about how many people see it, but how deeply it resonates. Macro influencers deliver scale, but nano and micro creators deliver trust – and in today’s skeptical digital landscape, trust is priceless.

Brands that prioritise peer-to-peer influence don’t just get impressions. They earn advocacy, loyalty, and growth.

Because the most valuable impression is the one that actually makes an impression.
