How SLX.marketing Was Born
In 2015, after nearly 20 years of running SiteLynx as a strategic SEM, founder Graham Hansell noticed a pattern:
The same problem kept happening:
Clients would go through expensive acquisitional campaigns. They’d get brilliant results. They’d nod enthusiastically. Then… nothing would happen to that traffic, leads went cold, sales lost.
From Consultancy Overflow to AI-First Agency
First Phase (2015-2021): Building the Foundation
In the early years, SLX was essentially the “implementation team” for SiteLynx’s consulting clients. We focused on:
- Marketing automation platforms (HubSpot, Marketo, Pardot)
- First-party data strategies (post-Cambridge Analytica reality)
- Multi-channel demand generation
- Analytics and attribution
What we learned: Most agencies overcomplicate things to justify their fees. We learned to simplify ruthlessly and measure everything against revenue contribution.
Turning Point (2020-2022): The AI Awakening
When GPT-3 launched in 2021, Graham saw what was coming. The entire “Search Economy” that had defined digital marketing for 25 years was about to transform into an “Answer Economy.”
The question became: How do you optimize for AI assistants, not just Google?
We started experimenting with:
- AI-assisted content creation (with human oversight)
- Schema optimization for answer engines
- Monitoring brand presence in ChatGPT and Perplexity
- Automated workflows using n8n and LLM APIs
The insight: AI wouldn’t replace marketers. It would replace marketers who refused to use AI.
step change (2023-Today): AI-First, Human-Guided
Today, SLX operates as an AI-first agency with human-in-the-loop oversight. We use AI to handle:
- Repetitive research and analysis
- First-draft content generation
- Real-time bid optimization
- Anomaly detection and reporting
While our human team focuses on:
- Strategic direction
- Creative concepts
- Brand voice and messaging
- Quality control and client communication
The result: We can execute faster, more efficiently, and more accurately than traditional agencies, while maintaining the human judgment that prevents AI from making stupid mistakes.

Trusted Partners in Your Digital Journey:
How We Work: The SLX Method
1. We Listen Before We Speak
The First Call: We do not pitch. We ask questions.
- What are you trying to achieve?
- What have you already tried?
- What does success look like in 90 days? 12 months?
Why this matters: Too many agencies have a hammer and see every client as a nail.
2. We Audit with Action in Mind
The Diagnostic Phase: We are not looking for things to criticise. We are looking for quick wins, strategic opportunities, wasted spend and competitor gaps.
Deliverable: A prioritised action plan, not a 40-slide deck.
3. We Execute, Then Iterate
The Operational Phase: We do not hand you a strategy document. We execute it.
- Weekly summaries of what we did and what is next
- Real-time access to all accounts and dashboards
- Direct communication with the people doing the work
- Monthly reviews with strategic adjustments
4. We Teach While We Work
The Education Layer: We explain our work in plain English, document our processes, train your team, and answer questions without making you feel stupid.
The goal: You should understand what we are doing and why. That is what real partnership looks like.

What We Value
No Ego, Just Results
We hire people who are confident in their expertise but humble in their delivery. If you cannot explain your work to a non-expert, you do not belong on our team.
Transparency Over Mystery
We do not gatekeep. Everything we do, we can explain – and we are happy to teach.
Action Over Analysis Paralysis
We bias toward testing and learning, not endless planning. Better to launch good work quickly and improve it than to wait for perfection.
Partnership Over Procurement
Our best client relationships feel like an extension of their team. We challenge, we advise, we execute – together.
Ready to Stop Reading Reports and Start Seeing Growth?
We work with companies turning over “a new leaf”, who are tired of agencies that confuse rather than deliver.
