In my previous company as the Head of Marketing, I went down the rabbit hole and looked for the best LinkedIn Ads Agencies out there.


I spent weeks poring over agency websites, got on calls, digging into case studies, and even had candid conversations with some of their clients.


If you’re a VP of Marketing who has seen fair share of “lead gen” hype, you’ll appreciate this no-fluff look at the top LinkedIn advertising agencies that actually move the needle.


1. AdConversion – The Demand Gen Powerhouse


I first came across the AdConversion agency when I was searching for an agency in my previous company that could deliver more than just a flood of low-quality leads.

What impressed me was their laser focus on demand generation, built around full-funnel strategies. This is an agency that doesn’t simply buy clicks. They craft ad experiences that nurture prospects from awareness to close.


What impressed me about AdConversion:

  • Structured Full-Funnel Approach: AdConversion’s 5 Stages Model ensures campaigns are methodically executed across every stage of the buyer’s journey. Create (brand affinity), Capture (converting in-market buyers), Accelerate/Activate (speeding up sales cycles or converting free trial users), Revive (re-engaging closed-lost opportunities), and Expand (driving revenue from existing customers).

  • Data-Driven Optimization: Their dedicated data team builds detailed dashboards, implements offline conversions, and provides real-time performance tracking to improve campaign effectiveness.

  • Always-On Automation: AdConversion uses an internal system to optimize ads 24/7, automatically pausing underperforming ads (e.g., CPSQL > $1,000), detecting ad fatigue (e.g., frequency > 5, CTR < 1%), and adjusting ad schedules for optimal performance.

  • Creative & Conversion-Focused Execution: AdConversion takes full ownership of design, copywriting, and landing pages, ensuring that every campaign asset is optimized for engagement and conversion. Their structured creative process ensures ads don’t just look good, they’re built to drive pipeline and revenue.

  • Transparent Pricing & No Hidden Fees: AdConversion does not lock you into long-term contracts and you can walk away from the partnership at any time. Unlike many agencies that charge a percentage of ad spend, AdConversion operates on a flat-fee model, ensuring your costs remain predictable without additional markup based on budget increases.


Bottom Line:
If you’re looking to transform LinkedIn from a lead-generator into a revenue engine, AdConversion is a partner that understands the entire buyer’s journey. Their pricing starts at $6,600/month.

2. Omni Lab – The Data-Obsessed Performance Marketers


Omni Lab
immediately caught my attention for its no-nonsense, demand-gen approach. Specializing in B2B SaaS, they prioritize tracking every micro-conversion that eventually builds into a significant pipeline.

When I dug into their methodology, what stood out was their commitment to transparency and measurable performance.


Key Takeaways on Omni Lab:

  • Pipeline Impact Over Vanity Metrics: Omni Lab insists that every ad dollar must correlate to revenue. Their dashboard isn’t cluttered with impressions and CTRs. They break down performance to show the exact pipeline impact.

  • Speed & Agility: They’re built for fast-paced environments. If you need a campaign to go live in days (not weeks), their lean processes and agile approach make that possible.

  • Sophisticated Retargeting: Their approach ensures that no high-intent lead slips away. They focus on keeping prospects engaged through precision audience segmentation, exclusion lists, and dynamic retargeting strategies that reinforce messaging across multiple touchpoints until they’re sales-ready.


Bottom Line:
Omni Lab’s pricing is based on your monthly ad spend. It starts at $3,665/month for a $5,000/month ad budget and it does not include creatives or copywriting.

3. Impactable – Affordable, Yet Highly Focused


Not every company has a massive ad spend, and that’s where Impactable comes in.

Originally known as a LinkedIn lead-generation shop, Impactable has evolved into a full-scale LinkedIn advertising agency without requiring a massive budget.


Their pitch is simple: deliver quality, demand-driven campaigns that are accessible to SMBs and startups alike.


What I Discovered About Impactable:

  • Cost-Effective Solutions: With plans starting under $849/month, Impactable makes LinkedIn advertising accessible. They’ve refined their process to squeeze maximum performance out of modest budgets.

  • Demand Generation Focus: While many agencies settle for generic lead gen, Impactable uses retargeting and personalized messaging to ensure that leads aren’t just numbers—they’re potential revenue drivers.

  • Strong Focus on Retargeting: They have one of the most robust strategies in place when it comes to retargeting. Their strategy takes into account all the different engagements a prospect could potentially have with you and makes the best use of everything that LinkedIn Ads has to offer.


Bottom Line:
Impactable offers a smart entry point into LinkedIn advertising without sacrificing quality. However, this pricing is applicable only if you want them to handle LinkedIn Ads. If you’re looking for an agency that can handle other channels, you’ll be paying extra.

4. B2Linked – Technical Mastery for High-Budget Campaigns

is where the deep technical expertise of LinkedIn advertising truly comes to light. Founded by AJ Wilcox, a recognized expert in the space, they bring a level of analytical rigor that few agencies can match.
