LinkedIn Ads Playbook (Part 9): The most expensive B2B LinkedIn mistakes (and how to avoid them)

To wrap the strategy, here are the big pitfalls we see – and how to sidestep them.

1). Using OR instead of AND in targeting

• Fix it with “Narrow” (industry → narrow → company size → narrow → job titles)

2). Letting “Accelerate” build your campaigns

• Always use Classic setup

3). Leaving Audience Expansion and LAN on by default

• Turn both off unless you’re running controlled tests

4). Relying on Website Conversions too early

• Start with Engagement / Traffic and strong conversion tracking

5). Messy naming and structure

• Use clear, descriptive names for campaign groups, campaigns and ads

6). Never checking which companies and titles you’re actually reaching

• Regularly audit company and job-title breakdowns

• Build negative lists for irrelevant segments

7). Treating LinkedIn as a lead vending machine

Focus on pipeline, revenue and sales signals, not just MQL counts

From agency dependence to LinkedIn marketing independence

Most B2B companies that come to us have tried LinkedIn ads before:

• A few leads, unclear ROI

• An agency that “owns” the account and the know-how

• A sense that LinkedIn should work for them, but no system to prove it

At BrandArchway, our approach is simple:

We don’t want to run your LinkedIn ads forever. We want to build your in-house LinkedIn engine and then make ourselves redundant.

That means:

• Designing your B2B LinkedIn marketing strategy together

• Structuring your account, targeting and tracking so you own it

• Training your team to run and optimise campaigns

• Documenting the system so you can scale it without us

If you want LinkedIn to be a reliable, in-house growth channel – not a recurring line item with unclear value – that’s exactly what we help build.
