Case Study Blog — From Invisible to Unmissable

When our recent client came to us, they had everything they needed to dominate their market online, except a strategy to make it happen.

An award-winning Scottish security training and close protection company with over 20 years of industry experience and a highly professional operation with a genuinely impressive story to tell.

But their social media? Telling almost none of it.

When we took over management of their Facebook, Instagram, and LinkedIn pages in February 2026, we inherited accounts that were active on paper but struggling to generate real results. LinkedIn had published one post in the entire previous month. Facebook engagement was declining despite posting volume going up. Instagram impressions had fallen by nearly 50%.

Within 60 days, the picture looked very different.

Metric	Result
Facebook interactions	+909%
LinkedIn interactions	+1,411%
LinkedIn impressions (MoM)	+197%
Total impressions in March	77,596

This is the story of how that happened and what it means for any business in a professional services or specialist sector that's currently underperforming on social.

The Client

The client operates across close protection, event security, residential security, and surveillance — alongside an extensive training academy delivering SIA licensing courses, first aid qualifications, and specialist security programmes.

Their credentials are serious and in other words: a business with real credibility, a genuine founder story, and a clear target market of corporate clients, high-net-worth individuals, and security professionals.

All of which makes the state of their social media at handover even more striking.

What We Inherited

Before we could build anything, we needed to understand exactly what we were working with. Our first act was a full audit of all three platforms, looking at performance data, content patterns, engagement rates, and audience demographics.

Here's what the January 2026 data showed us:

Metric	Value	Context
Total Impressions (all platforms)	35,923	Down 10.77% MoM
Facebook Interactions	157	Down 26.29% MoM
Instagram Impressions	3,569	Down 49.29% MoM
LinkedIn Posts Published	1	In the entire month
LinkedIn Followers	436	Effectively static
Facebook Posts Published	9	All Reels — no format variation

The pattern was clear. This wasn't a reach problem, it was a strategy problem. The accounts were being managed reactively: content published to tick boxes, without differentiation by platform, without a clear content framework, and without any real understanding of what the audience was responding to.

A few specific issues stood out:

• LinkedIn was being almost entirely ignored — a significant missed opportunity for a B2B professional services business whose ideal clients live on that platform.

• Facebook content was 100% Reels with no format variety. When engagement drops despite more content being published, that's a strong signal that format fatigue is setting in.

• Instagram was generating high volumes of posts but very low engagement. Multiple posts recorded zero likes, zero comments, and zero saves.

• The same content was being repurposed across platforms without adaptation — a copy-paste approach that ignores the very different algorithms and audience behaviours on each channel.

"The accounts had reach. What they didn't have was a strategy to convert that reach into results."

Our Approach

The brief was clear: stop the decline, establish a proper content strategy across all three platforms, and start building the kind of consistent, credible social media presence that a company of their standing deserves.

We approached this in three phases.

Phase 1: Stabilise and Diagnose (Weeks 1–2)

Before changing anything, we spent the first week understanding the data in depth. Which content had performed best and why? What was the audience demographic on each platform? Where was the engagement coming from, and where was it dying?

The Instagram audience data was particularly useful: 62.87% male, primarily aged 35–44, concentrated in Edinburgh, Glasgow, and London. This is the profile of a security professional or a corporate decision-maker, not a casual browser. Content needed to speak to that person directly.

On Facebook, the best-performing posts from the previous period weren't the training course promotions, they were the team and event content. People-first content was winning, and there wasn't nearly enough of it.

Phase 2: Rebuild the Content Framework

With a clear picture of what worked, we rebuilt the content approach from scratch, platform by platform.

Facebook

We introduced format variety immediately, moving away from Reels-only output to include static imagery and more conversational caption styles. Training and recruitment content was retained but repositioned — less product-push, more value demonstration. We also began integrating more team and event storytelling, which the data consistently showed drove higher organic engagement.

LinkedIn

This was the biggest opportunity. A professional security company with award-winning credentials and a founder with 20+ years of experience is exactly the kind of business LinkedIn was built for, and it wasn't being used at all.

We moved from 1 post per month to consistent weekly publishing, focused on three content pillars:

• Authority and credibility — accreditations, expertise, track record

• Career and professional development — targeting security professionals and potential recruits

• Values-led content — company culture, team, and founder narrative

The results were immediate. Within the first month of consistent posting, LinkedIn interactions increased by 1,411% and followers began growing meaningfully, up from 436 at handover to 485 by end of February, and 577 by end of March.

Instagram

The Instagram strategy was rebuilt around a fundamental shift in how we measure success. Likes and follower counts are increasingly less relevant on the platform — the algorithm now heavily rewards saves and DM shares. We refocused the content approach on producing posts that people want to send to someone else: useful, specific, visually strong.

Phase 3: Scale What Works

By March, we had enough data to know what was working and why. The focus shifted to scaling the highest-performing content types while continuing to develop their longer-term content assets.

We also began developing content around founders personal narrative — his 20+ years in the industry, building the business from limited capital, and the philosophy behind Adamantine Global's training approach. Founder-led content consistently outperforms branded content on LinkedIn.

The Results

Here's what the data looks like across the full three-month period.

Metric	Jan 2026	Feb 2026	Mar 2026
Total Monthly Impressions	35,923	41,784	77,596
Total Interactions (all platforms)	213	1,870	3,307
Facebook Impressions	30,600	36,510	62,270
Facebook Interactions	157	1,585	2,539
LinkedIn Impressions	1,754	4,445	13,190
LinkedIn Interactions	18	272	757
LinkedIn Posts Published	1	11	10
LinkedIn Followers	436	485	577
Facebook Followers	1,167	1,192	1,282

Every key metric improved across both months. But the results that stand out most aren't just the percentage increases, it's the trajectory. Look at the LinkedIn impressions column: from 1,754 to 4,445 to 13,190. That's not a one-off spike. That's compounding growth from consistent, quality content.

The Post That Changed Everything

The single best-performing piece of content across the entire three-month period was published on 16 February 2026, our second week managing the account.We wrote the post, structured it for maximum shareability, timed it correctly, and published it across Facebook and LinkedIn simultaneously.

Metric	Result
Video views (Facebook)	14,260
Reach	8,997
Engagement rate	11.1%
Organic shares	17
Reactions	129
Comments	22

No paid promotion. No boosting. Pure organic reach, driven by a post that was written with a clear hook, structured to encourage sharing, and published at the right time to the right audience.

"The highest-performing post of a three-month period wasn't the most elaborate. It was the most strategically considered."

What This Case Study Teaches Us

These results aren't a fluke, and they're not unique to the security industry. The same principles apply to any professional services, B2B, or specialist business that's currently underperforming on social.

1. Posting more rarely solves a strategy problem

Their previous agency was publishing 27 posts a month and still seeing declining engagement. Volume isn't the answer. Platform-specific, audience-led content is. If your content isn't working, adding more of it usually makes things worse, not better.

2. LinkedIn is the most underused platform in professional services

If you're in any kind of B2B, specialist, or professional services business and you're not actively publishing on LinkedIn, you're invisible to people who are actively looking for what you offer. The decision-makers, procurement teams, and senior buyers who might hire a company like theirs are on LinkedIn, and they form opinions about businesses based on what they see there. Or don't see.

3. Platform differentiation is non-negotiable

Facebook, LinkedIn, and Instagram have fundamentally different algorithms, different audience behaviours, and different content cultures. What works on one will often fail on another. A cross-posting strategy — the same caption on every platform — is one of the most common and most costly mistakes we see.

4. People-first content consistently outperforms promotional content

The data across three months was consistent on this: team content, event content, founder narrative content, and values-led content outperformed service-promotion posts on every platform. This doesn't mean you stop promoting, it means you build an audience with content they care about, and then they're ready to hear what you offer.

5. The results compound

LinkedIn went from 1,754 impressions in January to 13,190 in March. That's not a straight line, it's a curve. Consistent quality content builds algorithmic momentum, audience trust, and organic reach over time. The businesses that see the biggest long-term returns from social media are the ones who commit to consistency, not the ones who post in bursts.
