B2B Influencer Marketing Examples on LinkedIn, With Real Numbers

The best-documented B2B influencer marketing examples on LinkedIn show what is actually measured: reach, engagement against a benchmark, cost per click and, occasionally, signups. This post collects 13 examples with real numbers. Six are public campaigns from other brands, each linked to its source. Seven are sponsored posts by Tom Hunt, Fame's founder, on his own profile, labelled as such.

Nearly all of these numbers are self-reported by the agency, vendor or creator involved, and none has been independently audited. They are useful for seeing what good reporting looks like and how widely outcomes vary. They are not forecasts. For the wider strategy behind them, start with our guide to B2B influencer marketing.

How to read these examples

Three distinctions matter more than any headline figure.

• Paid creators versus amplified insiders. Some examples involve outside creators. Others put ad spend behind posts from a company's own founder or staff, using LinkedIn's Thought Leader Ads. Both are relevant, but they are different activities.
• Organic versus promoted. A post with paid amplification buys some of its impressions. Comparing it with an unpromoted post tells you little.
• Impressions versus potential reach. Impressions count times a post was shown. Potential reach usually adds up audiences that could have seen something, so it is a much softer number.

We have kept each source's own wording for its metric, and noted where a figure is an estimate. If any term is unfamiliar, our B2B influencer marketing glossary defines it.

Campaigns using outside creators

1. LinkedIn Sales Solutions: Authenticity in Sales

TopRank Marketing's case study on the Authenticity in Sales campaign describes a six-week activation with nearly 40 engaged advocates, including social-first content co-created with influencers. It reports an estimated reach of more than 656,000 and a LinkedIn engagement rate more than 167% above benchmark.

What to take from it: the campaign was measured against a stated engagement benchmark rather than against nothing. Note that reach is an estimate and the page does not report pipeline.

2. LinkedIn: an always-on influencer programme

In a second TopRank case study, the agency built an always-on strategy for LinkedIn's existing influencer programme. It reports nearly 2,000 brand mentions by influencers and their networks, 84 million in potential reach from those mentions, and engagement 200-450% above benchmark on one social activation.

What to take from it: the programme was run continuously rather than as a one-off burst. The 84 million is potential reach, and the engagement figure comes from a single activation, so neither describes the whole programme's delivered results.

3. Hootsuite: research shared by LinkedIn creators

The Social Standard, an influencer agency, wrote up Hootsuite's LinkedIn creator campaign, in which about eight creators shared findings from a Hootsuite study aimed at social media managers. The write-up says that for about half of the creators, engagement doubled over four weeks.

What to take from it: original research gave the creators something specific to talk about. This write-up reports creators' engagement rather than any business outcome for Hootsuite.

Campaigns amplifying founders and employees

These three are not paid creator deals. They matter because they show what paid distribution can do for a post from a real person, which is the same mechanism you would use on a creator's post in a later phase. Our guide to LinkedIn Thought Leader Ads covers how the format works.

4. RB2B: promoting a founder's best organic posts

Understory Agency's RB2B case study describes promoting 25 of founder Adam Robinson's existing posts, plus some posts other people wrote about RB2B, with no new creative beyond adding a call to action. Reported at 22 days in: roughly 20% click-through on video creative, 98 click conversions, and a blended cost per free signup of roughly $22 (roughly $57 on click-through alone).

What to take from it: the agency reports both a blended and a click-only cost per signup. The gap between them is a good reminder that how you attribute a result can more than double its apparent cost.

5. Valueships: Thought Leader Ads against image and carousel

ZenABM's Valueships write-up compares formats over roughly two weeks in early 2026. Thought Leader Ads spent $391 for 169,571 impressions at a $2.31 CPM. Single image ads spent $3,076 at a $48.31 CPM, and carousels $2,736 at a $55.38 CPM.

What to take from it: treat this as an extreme outlier. The spend is small, the formats may not have run for equal periods, the author's company sells the measurement tool used, and the author herself frames the result as hard to replicate. It is here because the numbers are published in full, not because you should plan on them.

6. Metadata: employee posts against brand awareness ads

Metadata published its own Thought Leader Ads experiment, promoting posts from three employees. It reports click-through of about 2.5 times its benchmark for image and video brand awareness ads, and an average CPC of $4.14 against $12.54 for those ads. One post reached 6.64% CTR while the other two sat at 2.65% and 2.78%.

What to take from it: even inside one small test, one post earned far more than the others. The author also calls it too soon for a verdict, which is a more honest conclusion than most case studies reach.

Tom Hunt's own sponsored posts

The remaining seven are sponsored posts Tom Hunt ran on his own LinkedIn profile, which has 220,000 followers. They are Tom's own posts, not results from Fame's creator roster. Fame has no roster campaign results to publish yet, so please do not read these as a forecast for a Fame Influencer campaign.

Promoted means the brand paid LinkedIn to amplify the post, so those impressions are not organic reach. Where the table says not recorded, Fame's records do not show whether the post was promoted, so do not assume it was purely organic.

Example	Brand	Impressions	Paid amplification
7	HP + AMD	4,570,951	Promoted
8	monday.com	1,091,963	Promoted
9	Raylo	350,304	Not recorded
10	BetterPic	52,562	Not recorded
11	Taplio	12,743	Not recorded
12	Airwallex	9,799	Not recorded
13	PolyAI	5,702	Not recorded

The full list, including further posts and the date the analytics were taken, is on our sponsored LinkedIn post examples page.

The useful part is the spread. The same person on the same profile produced posts roughly 800 times apart, from 5,702 to 4,570,951 impressions, although the two largest had paid amplification behind them. Among the five with no promotion recorded, the largest is still more than 60 times the smallest. Any single post is a poor guide to what the next one will do, which is why a campaign should be judged across several placements.

The third-party examples side by side

Brand	Type	Headline result	Reported by
LinkedIn Sales Solutions	Nearly 40 advocates, six weeks	656k+ estimated reach; LinkedIn engagement 167%+ above benchmark	TopRank (agency)
LinkedIn	Always-on programme	Nearly 2,000 mentions; 84M potential reach	TopRank (agency)
Hootsuite	About eight creators	Engagement doubled for about half the creators over four weeks	The Social Standard (agency)
RB2B	Founder posts, Thought Leader Ads	Roughly $22 blended cost per free signup	Understory (agency)
Valueships	Co-founder posts, Thought Leader Ads	$2.31 CPM on $391 spend	ZenABM (vendor)
Metadata	Employee posts, Thought Leader Ads	$4.14 CPC against $12.54	Metadata (the brand)

What the examples have in common

A set of 13 self-selected examples cannot prove anything about the channel as a whole. Published case studies skew towards wins. Still, some practical patterns are visible.

• Specific material travels. Hootsuite gave creators research findings, and RB2B and Metadata promoted posts with a concrete point of view rather than generic brand messages.
• Outcomes vary widely within a campaign. Metadata's and Tom's numbers both show large gaps between posts, so one placement is a weak test.
• Benchmarks make numbers meaningful. The most useful write-ups compare against a stated baseline, such as a benchmark engagement rate or the brand's own image ads.
• Few reach revenue. RB2B reports signups, but none of these sources reports closed revenue from the activity. That is a measurement gap, and worth closing in your own campaign.
• Audience quality is rarely reported. Hardly any public example says how many engagers matched the buyer profile, even though that is the question a B2B marketer most needs answered.

What these numbers cannot tell you

A big impression count does not tell you who saw the post. For a B2B brand selling to a narrow audience, 50,000 impressions among buyers may be worth more than a million among everyone else. It also does not tell you whether the post was inflated by engagement pods, where groups of people trade comments and likes to game the feed.

When you read any case study, including ours, ask the same questions:

• Who published this, and do they sell something related?
• Was paid amplification involved, and is it disclosed?
• Is the number delivered impressions or estimated reach?
• What is the comparison, and over what period?
• Do we know who engaged, by company and role?

How to get numbers worth publishing

If you want your own campaign to produce a useful case study, decide the report before the first post goes live.

• Run several placements across several creators, so one outlier does not decide the verdict.
• Record named engagers by company and role, then work out what share match your ideal customer profile. Our post on how to measure the ROI of B2B influencer marketing explains the calculation.
• Report a blended CPM across all placements and compare it with your LinkedIn Ads results.
• Separate promoted from unpromoted impressions from day one.
• Write a clear brief using our free LinkedIn creator brief template, so the creator has something specific to say.

This is how Fame Influencer is set up: sponsored posts on vetted creators' own profiles, for B2B tech and SaaS, with reports covering named engagers by company and role, ICP-engagement percentage, blended CPM against LinkedIn Ads benchmarks and a placement counter. The test campaign is five placements with five creators over two months for $9,500, and full details are on the pricing page.
