Disclosure and Methodology
Kiin is a LinkedIn Ads agency and we are on this list. Every "best agencies" article is published by someone with an interest, usually without saying so. We would rather say it first and give you enough detail to disagree with us.
What each agency is scored on:
- LinkedIn specialisation — is LinkedIn the core offer or one channel among many?
- Measurement honesty — do they report landing page clicks or LinkedIn's inflated total click figure?
- Funnel coverage — do they build a mid-funnel, or just cold ads and demo requests?
- Pricing transparency — published, or extracted on a call?
- Verifiable credentials — partner status, team background, named clients, published data
Not scored on: agency size, awards, or how good the website looks.
The Agencies
1. Kiin — best for full-funnel LinkedIn plus signal-based outbound
Three ex-LinkedIn Marketing Solutions employees on an eight-person team. LinkedIn Agency Partner with Marketing API Standard tier, and operates its own LinkedIn Ads MCP server benchmarking against 1,000+ connected accounts. Publishes the largest independent thought leader ads study — $8.4M of TLA spend, paired within account — which is the closest thing the category has to neutral benchmarks.
The differentiator is running LinkedIn Ads and signal-based outbound off one dataset, so ad engagement feeds outbound rather than the two paying separately for the same audience. Reporting is on landing page clicks. Half the client base is American; the account is worked during US overnight hours from London.
Where we are the wrong choice: under $3,000 a month in spend, transactional products with short cycles, or if you want someone who also runs your TikTok. We do B2B and mostly we do LinkedIn.
2. B2Linked — best for pure LinkedIn tenure
AJ Wilcox has run LinkedIn Ads and nothing else for over a decade, with a large managed-spend history and the best-known podcast in the category. If the single thing you care about is how long the agency has been doing exactly this, B2Linked has more of it than anyone.
Tradeoff: LinkedIn only, by design. If you need Google or Meta run alongside, or outbound connected to the ad data, it is a second vendor.
3. Impactable — best for cybersecurity and fintech
Justin Rowe's agency has deep vertical concentration in cybersecurity and fintech and publishes prolifically — benchmark posts, a free audit checklist, a steady stream of data on LinkedIn. Strong choice if you sit squarely in one of their verticals and want a team that has seen fifty accounts like yours.
Tradeoff: vertical depth cuts both ways; outside their core verticals the advantage narrows.
4. AdConversion — best for teams who want to learn as well as outsource
Silvio Perez runs AdConversion as an education business with an agency attached, with a large body of free training on LinkedIn and Google Ads. Suits teams building in-house capability who want execution alongside it.
Tradeoff: if you want the work done and never want to think about Campaign Manager, the educational framing is overhead you are paying for.
5. Directive — best for enterprise performance marketing at scale
A large performance marketing agency with a SaaS focus, running paid search, paid social, SEO and CRO for mid-market and enterprise software companies. LinkedIn is one channel within a full performance program, run at a scale few specialists can match.
Tradeoff: LinkedIn is not the core offer, and enterprise process comes with enterprise minimums. For a Series A company spending $8,000 a month on LinkedIn it is the wrong shape.
6. UK and European specialists — for UK or EU audiences
If your ICP is in the UK or Europe, the audience-size and job-title differences are large enough that local knowledge is worth more than tenure. We keep a separate list of UK LinkedIn Ads agencies with the same criteria, and a London version.
7. Offshore flat-fee options
GrowthSpree and similar run LinkedIn at a low flat fee, often around $3,000 a month, from lower-cost regions. The economics are genuinely attractive. The tradeoff is time-zone overlap, cultural fluency with the buyer, and how much senior attention the account gets at that price. If the ICP is global and the budget is tight, it can be the right call.
What "Good" Looks Like Before You Hire Anyone
Any agency on this list will send you a case study. Ask instead what their accounts look like against the platform. From Kiin Labs' 2026 study of 464 thought leader ad accounts:
| Metric (thought leader ads, medians) | Value | Ask the agency |
|---|---|---|
| Landing page CTR | 0.46% | "Do you report this or total CTR?" |
| Engagement rate | 4.46% | "What share of clicks reach a landing page?" (Answer: about 9%) |
| Landing page cost per click | $14.71 | "What is your median LP CPC across accounts?" |
| CPM | $65 | "How do you set bids?" (63% of LP CPC variance is CPM) |
| True frequency | 9.5 (reported: 3.5) | "How do you measure frequency across campaigns?" |
An agency that cannot engage with these numbers is reporting to you from Campaign Manager's default view, which is the view LinkedIn designed.
How to Actually Choose
- "Do you report clicks or landing page clicks?" If they do not immediately know the difference, everything they have ever reported has been inflated. The single most revealing question.
- "Show me a mid-funnel campaign you built." If they cannot show a retargeting layer segmented by engagement depth, they build half a funnel.
- "Is your fee a percentage of spend?" Percentage-of-spend pays the agency more for spending more. Ask why they chose their model.
- "Who works on my account?" Is the person in the pitch the person doing the work?
- "Can you connect spend to pipeline?" If the answer is cost per lead, they measure the top of your funnel and call it results.
