LinkedIn Ads Agency for B2B

The short answer

Tack Media builds and runs LinkedIn Ads for B2B companies with long sales cycles and high deal values. The work covers audience architecture, Lead Gen Forms, the Conversions API, CRM write-back and pipeline reporting rather than lead-count reporting. Engagements start at $5,000 a month.

What we actually do with LinkedIn Ads

LinkedIn is the most expensive click in B2B and the most precise targeting available. Both facts have to be respected or the channel loses money quickly.

• Audience architecture. Job function, seniority and company size layered properly, matched audiences from your CRM lists, website retargeting by page intent, and lookalikes built off closed-won rather than off all leads.
• Campaign structure by objective. LinkedIn offers Sponsored Content, Sponsored Messaging, Text Ads and Dynamic Ads across awareness, consideration and conversion objectives. We do not run one format and call it a test.
• Lead Gen Forms with real routing. Forms that pre-fill from the profile, then land in the CRM within seconds with campaign, creative and audience attached. A lead sitting in the LinkedIn UI for three days is a lost lead.
• Conversions API. Server-side conversion streaming so LinkedIn optimises toward qualified opportunity, not toward downloads.
• Content and offer design. LinkedIn punishes weak offers harder than any other channel. We build the asset, the landing page and the follow-up sequence together, which is why this usually runs alongside our organic and content work.
• Pipeline reporting. Cost per qualified opportunity and cost per closed-won by campaign, not cost per lead.

What it connects to

Where teams get stuck

Leads that never leave LinkedIn. Lead Gen Forms convert well and then sit in an export screen. The fix is one of the documented paths in the LinkedIn Marketing API program, which covers advertising, lead sync and reporting modules, wired into the CRM with an owner assigned automatically. If your process involves someone downloading a CSV on Monday, the channel will look worse than it is.

Versioned APIs that expire underneath you. This is the single most common cause of a LinkedIn integration going quiet. LinkedIn publishes new API versions monthly and supports each for a minimum of one year, and the Linkedin-Version header in YYYYMM format is mandatory on every call. Integrations built once and never revisited stop working on a schedule you can predict, which means you can also prevent it.

Conversions API limits ignored at scale. LinkedIn documents them precisely: 5,000 conversion events per batch request, 600 requests per minute, 500,000 requests per day, and a 90-day conversion lookback window, as of 26 August 2026. That 90-day window matters most: if your sales cycle is six months, closed-won cannot be sent back as a conversion event and you need a different attribution model. Vendor limits change, so we verify them at each build.

Treating LinkedIn CPCs like search CPCs. The click costs what it costs. The only defence is a higher-value offer and tighter qualification, not a lower bid.

How it works — 1, 2, 3

1. Audit and access, week 1 to 2. Campaign Manager, Insight Tag, CRM and existing content assets. We map your ICP against what LinkedIn can actually target, and tell you where the two do not overlap.
2. Build and connect, week 2 to 6. Insight Tag and Conversions API first, then audiences, then campaigns. Lead routing into the CRM is tested with live submissions before spend scales.
3. Run and report, ongoing. Weekly optimisation, monthly pipeline review. Expect eight to twelve weeks before cost per opportunity is a trustworthy number, because B2B sales cycles are slow and early data lies.

What it costs

Tack engagements start at $5,000 a month. What moves the number: number of target segments and geographies, whether we produce the content offer or you supply it, whether ABM list management is in scope, and how deep the CRM integration goes.

LinkedIn does not publish a fixed platform fee. Its own advertising pages state you can start with any budget and stop at any time, with cost set by auction. In practice, B2B CPCs on LinkedIn are the highest of the major platforms, and a test that produces a readable result usually needs several thousand dollars a month in media on top of the retainer. Media is billed by LinkedIn to your card, not to us.

Questions we get asked

Who owns the Campaign Manager account?

You do. It sits under your company page and your billing. We take manager access and give it back on request. Your Insight Tag data, matched audiences and conversion history stay with you.

Can we bring it in-house later?

Yes. Audience definitions, the conversion map, the routing logic and the version-header maintenance schedule are all documented as part of the system we build.

Do you work with our existing setup?

Usually yes. We keep the account and Insight Tag history. What we typically replace is the lead routing, because that is where most of the value is being lost.

What if our sales cycle is longer than the attribution window?

Then we do not pretend otherwise. We optimise on a mid-funnel proxy that we can prove correlates with closed-won, and report true attribution out of the CRM instead of out of Campaign Manager.

Do you also build the follow-up automation?

Yes. Enrichment, routing, sequencing and alerting are part of our automation and AI work. Tack are integrators, not trainers.

The bottom line

LinkedIn works for B2B when the offer is strong, the lead reaches a human quickly, and success is measured in pipeline rather than in downloads. Get those three right and the high CPC stops being the problem.
