Why does LinkedIn perform so differently between MSPs and ERP consultancies?

Cycle length, buying committee size and audience price-sensitivity all change the playbook. MSPs run shorter cycles (one to four months) with smaller committees and respond best to practical creative on response-time SLAs and security posture. ERP consultancies run twelve to eighteen month cycles with larger committees including the CFO, COO and IT director, and audiences need named clients and sector-specific case studies. The same budget treated identically across both verticals will under-perform in one or the other every time.

What is a realistic minimum LinkedIn budget for cybersecurity vendors?

Around £8,000 a month for a serious programme. Cybersecurity is the most competitive LinkedIn vertical we work in, with CTRs routinely half what we see elsewhere and CPMs running 30 to 50 per cent above the IT services average. Below £8,000 frequency drops too low to overcome creative fatigue in an audience that is being shouted at by every other vendor. Document ads outperform single-image ads consistently here, and audience filters by industry, regulatory regime and security maturity work harder than seniority alone.

Should small horizontal SaaS tools run LinkedIn Ads at all?

Usually no. The economics dictate the strategy. A horizontal SaaS tool with a £40 a month plan rarely justifies LinkedIn CPMs and the longer payback period the channel requires. A vertical SaaS platform with £30,000 ACVs absolutely should. The break-point is roughly where customer lifetime value justifies a CPL of £180 to £400, which is the realistic range for mid-market and enterprise SaaS on LinkedIn. Below that, paid search and content-led acquisition tend to make the maths work better.

LinkedIn Ads for IT services: a vertical-by-vertical breakdown

LinkedIn Ads is rarely a single channel with a single set of benchmarks. The same budget, the same creative process and the same campaign structure produce wildly different results depending on which slice of IT services you sit in. We see managed services firms generating opportunities at half the cost-per-acquisition of cybersecurity vendors, and ERP consultancies needing twice the consideration runway of either.

Treating LinkedIn as one playbook is one of the more expensive mistakes we see when auditing accounts. Below is how performance, audience targeting and creative tend to differ across the verticals we work in most often, and what that means for budget split and patience.

Managed service providers

MSPs are the most price-sensitive vertical we run LinkedIn for, and the one where targeting tends to drift fastest. The instinct is to broaden audiences (“any IT manager in the UK”) to bring CPCs down. The result is form fills from one-person businesses and inbound that wastes the SDR team’s time.

The MSP audiences that work for us are tightly bounded by company size (usually 50 to 500 employees), industry (often professional services, finance, manufacturing) and geography (we run regional MSP campaigns at postcode-cluster level). Job titles tend to be IT manager, head of IT, operations director and managing director in smaller firms.

Creative skews practical: response-time SLAs, security posture screenshots, comparison tables against the in-house option. Glossy “transformation” messaging underperforms reliably here. Our Google Ads for MSPs geo playbook covers how the regional layer carries across into search, and the LinkedIn Ads B2B tech playbook is the fundamentals piece for the structure we apply across all verticals.

Budget reality: a serious MSP LinkedIn programme rarely works under £6,000 a month. Below that the auction punishes you on frequency.

ERP and business systems consultancies

ERP is the longest cycle we run paid for. Selection processes regularly take twelve to eighteen months, the buying committee is large (finance director, IT director, COO, sometimes CEO) and the cost-per-lead conversation is almost always misleading.

The audiences that perform here are senior. We target finance directors and CFOs, COOs, IT directors and heads of transformation, in companies typically £20m to £500m turnover. Industry filters matter: a consultancy specialising in manufacturing ERP wastes budget appearing in front of professional services prospects, even when the platform looks similar on paper.

Creative leans into proof. Named clients, sector-specific case studies, vendor partnerships (NetSuite, Microsoft Dynamics, SAP Business One) all stop the scroll. We tend to use document ads heavily here for sector buyer’s guides and ROI calculators, and we set expectations that the first three months are about audience-building rather than conversions. The audience for an ERP rebuild simply does not raise their hand quickly.

Cybersecurity vendors and consultancies

Cybersecurity is the most competitive LinkedIn vertical we work in, and the one with the most creative fatigue. Every vendor is shouting. CTRs are routinely half what we see elsewhere, and CPMs in the security audience can run 30 to 50 per cent above the IT services average.

What works: specificity. A firm selling to financial services compliance teams should not be running creative aimed at “all CISOs”. Audience filters by industry, regulatory regime (FCA-regulated firms, NIS2-affected, etc.) and security maturity work harder than seniority alone. We also see noticeably better engagement on creative that names a threat, an audit failure mode or a compliance deadline rather than generic “protect your business” messaging.

Document ads outperform single-image ads consistently in this vertical. A 12-page incident response playbook gets opened. A static “book a demo” ad does not. We pair this with retargeting from organic content, and the retargeting tech buyers approach maps closely.

SaaS and software vendors

SaaS is the broadest of the four, because the variance within it is enormous. A horizontal SaaS tool with a £40 a month plan should not be running LinkedIn at all in most cases. A vertical SaaS platform with £30,000 ACVs absolutely should. The economics dictate the strategy.

For mid-market and enterprise SaaS, we usually run a three-stage funnel: awareness against ICP, consideration through value content, decision through demo and trial offers. The split is roughly even across the three for a maturing brand, weighted more heavily towards awareness when launching into a new vertical or geography. Our piece on demand-gen vs lead-gen budget is the underlying framework here.

Creative tends to be product-led: short demo clips, dashboard screenshots, integration logos, customer quotes. SaaS buyers want to see the thing. Abstract messaging gets scrolled past as quickly as in cybersecurity, but the failure mode is different: too vague rather than too noisy.

A rough comparison

Vertical	Typical CPM	Reasonable CPL	Min monthly budget	Cycle length
MSP	£30 to £55	£150 to £300	£6,000	1 to 4 months
ERP consultancy	£40 to £70	£300 to £600	£10,000	9 to 18 months
Cybersecurity	£45 to £80	£250 to £500	£8,000	3 to 9 months
SaaS (mid-market)	£35 to £65	£180 to £400	£8,000	3 to 6 months

These are not LinkedIn’s official benchmarks. They are the ranges we see across UK B2B tech accounts we manage or audit, and they shift quietly. CPMs in particular have crept up year on year as more vendors have moved budget into the channel.

What does not vary

A few things stay constant regardless of vertical. The auction rewards consistent spend. Stop-start budgets confuse the platform and rebuild costs every time you pause. Frequency caps matter, and exclusion stacks across awareness, consideration and decision audiences prevent self-cannibalisation.

Conversion tracking matters more in long-cycle verticals like ERP than in shorter SaaS cycles, but it matters everywhere. Pushing offline conversions back from the CRM into LinkedIn is the difference between optimising against form fills and optimising against opportunities. Our conversion tracking guide for long B2B sales cycles covers the mechanics, and the broader attribution models piece explains how we read the data afterwards.

Where the budget actually goes

The temptation in any vertical is to overweight the bottom of the funnel, because that is where the platform reports conversions. The accounts that scale do the opposite. They build an audience patiently, retarget warm engagement through value content and only ask for a meeting once the audience is actually ready.

That requires holding your nerve through the first two or three months, which most internal marketing teams find difficult to do alone. It also requires a creative pipeline that does not exhaust itself in week three. Both are easier to plan when you accept that LinkedIn is not a uniform channel, and that the right structure for an MSP is genuinely different to the right structure for an ERP consultancy.

If you are running LinkedIn across IT services and the numbers feel inconsistent, the underlying cause is usually a mismatch between the playbook and the vertical. We work through this regularly on our paid media service. Working through any of this on your own account? Tell us where you’re stuck.
