Most businesses comparing marketing agencies today are still using yesterday's criteria.
They look at:
Those things still matter.
But search has changed.
The way people discover businesses has changed.
And increasingly, the agencies that help businesses thrive aren't necessarily the ones chasing rankings. They're the ones helping brands become visible wherever discovery happens.
That could be:
This shift is forcing businesses to ask a different question:
Do we need a digital growth agency, or do we need a visibility agency?
That question sits at the heart of any comparison between GEO agencies like Tenacious AI Marketing and Passion Digital.
Both agencies understand modern search.
Both have embraced AI search.
Both help businesses improve visibility.
But they approach the challenge from very different directions.
For years, SEO was largely about rankings.
The logic was straightforward:
Higher rankings generated more traffic.
More traffic created more opportunities for leads and revenue.
That model still matters.
However, search behaviour is evolving.
Research from SparkToro and Datos found that nearly 60% of Google searches now end without a click.
This highlights an important reality:
Visibility increasingly happens before users ever visit a website.
People are receiving
without clicking through to a traditional search result.
At the same time, Gartner predicts that traditional search engine volume will decline by 25% by 2026 as users increasingly shift towards AI chatbots and virtual agents.
The broader trend is becoming difficult to ignore.
For a deeper breakdown of why traditional search is no longer enough, watch Search Is Broken | Here’s What Replaces It, which explains why Google alone is no longer a growth strategy and why search should now be understood as behaviour, not just a search box.
Adobe's latest research also found that traffic from AI sources to U.S. retail websites grew 393% year-over-year in Q1 2026, highlighting how quickly AI-driven discovery is expanding.
As AI search grows, businesses need to think beyond rankings alone.
They need to think about discoverability.
And that is where the difference between Passion Digital and Tenacious AI Marketing begins to diverge.
This wider shift is covered in The New Rules of AI Search: 4 Strategies Every Brand Needs to Win Citations, which explains why brands now need to optimise for citations, answer selection, and recommendation visibility.
At a high level, both agencies help businesses become more visible online.
That's where the similarities begin.
Passion Digital combines:
Its model is built around helping businesses grow across multiple acquisition channels.
Tenacious combines:
Its model is built around helping businesses remain visible as search evolves.
Neither approach is inherently better.
They simply solve different problems.
One of the clearest differences is how the agency defines visibility.
Tenacious argues that businesses need to become visible not only within search engines but within the places AI systems look for trusted expertise.
This includes:
The objective is not simply to improve rankings.
The objective is to increase the likelihood that a business becomes a trusted answer when AI systems generate recommendations.
This philosophy influences both strategy and measurement.
Alongside GEO and AEO, Tenacious places a strong emphasis on understanding how businesses are discovered, cited and recommended across modern search environments.
Tools such as Answer Architect help businesses identify visibility gaps, understand where competitors are being cited and uncover opportunities within AI search conversations.
Alongside this, the Organic Visibility Scorecard gives businesses a clearer picture of how visible they are across modern search environments.
In just a few minutes, it highlights visibility gaps, AI search opportunities and areas that may be limiting discoverability across platforms such as ChatGPT, Google AI Overviews and other AI-powered search experiences.
Rather than focusing purely on rankings, it helps businesses understand how prepared they are to be found, cited and recommended as search continues to evolve.
Together, these frameworks reflect a wider belief that rankings alone are no longer enough to understand visibility.
The goal is not simply to rank.
The goal is to become a trusted answer wherever discovery happens.
Passion Digital is a broader digital growth agency.
Businesses working with Passion can access a wide range of services covering both acquisition and optimisation.
That includes:
More recently, Passion Digital has expanded into AI search through services including:
The advantage of this model is integration.
A business can align:
through a single agency relationship.
For organisations seeking broader digital growth support, that can be extremely valuable.
The focus isn't just visibility.
It's overall marketing performance.
Most agency comparisons focus on services.
But services rarely explain outcomes.
The real difference lies in how each agency thinks about visibility.
Passion Digital helps businesses improve performance across multiple marketing channels.
Tenacious focuses on helping businesses strengthen discoverability across an increasingly fragmented search ecosystem.
One approach is broader.
One approach is more specialised.
That distinction becomes important when businesses start asking questions such as:
Those are visibility questions.
Not ranking questions.
And they require a different measurement framework.

This is perhaps the most interesting area of comparison.
Unlike many traditional agencies, Passion Digital has invested meaningfully in AI search.
Its AI search offering includes:
For readers who want the wider definition first, What Is GEO in 2026 and How Do You Get Cited in AI explains how GEO works as a visibility discipline beyond traditional SEO.
The agency also uses tools such as Otterly.ai to help businesses monitor AI search visibility.
Tenacious approaches AI search from a visibility-first perspective.
Rather than treating GEO as a standalone service, it forms part of a broader ecosystem that includes:
The difference isn't whether either agency understands AI search.
Both clearly do.
The difference is how central AI visibility is to the wider agency offering.
| Capability | Tenacious AI Marketing | Passion Digital |
| SEO | Part of a broader visibility strategy | Part of a broader digital growth strategy |
| GEO | Yes | Yes |
| AEO | Yes | AI Search Services |
| AI Visibility Strategy | Core focus | Part of wider growth services |
| AI Discoverability | Core focus | Included within AI search services |
| Authority Building | Strong focus | Not a standalone service area |
| Citation Visibility | Strong focus | Included within AI search initiatives |
| Search Everywhere Optimisation | Yes | Not publicly referenced |
| LinkedIn Visibility | Strong focus | Not prominently featured |
| YouTube Visibility | Strong focus | Not prominently featured |
| AI Visibility Measurement | Answer Architect, Organic Visibility Scorecard and visibility assessments | AI Search Reporting and LLM Performance Tracking |
| PPC | No | Yes |
| Paid Social | No | Yes |
| CRO | No | Yes |
| Analytics | Limited focus | Yes |
| Digital PR | Not a primary service focus | Yes |
If your primary objective is:
Passion Digital is likely to be the stronger fit.
Its service offering spans multiple acquisition channels and provides a broader growth solution.
For businesses looking for one agency to manage performance across several disciplines, this model makes a lot of sense.
If your primary objective is:
Tenacious AI Marketing is likely to be the stronger fit.
Not because Passion lacks AI search expertise.
But because AI visibility sits at the centre of the Tenacious approach rather than alongside other marketing services.
This is where the distinction becomes even clearer.
Tenacious places a much greater emphasis on:
The agency's view is that people increasingly trust people before they trust brands.
That means authority signals often originate from founders and subject matter experts rather than company websites alone.
For founder-led businesses, professional services firms and specialist consultancies, this can be particularly relevant.
Choose Passion Digital if:
Choose Tenacious AI Marketing if:
The biggest mistake businesses make when comparing agencies is assuming there must be a winner.
In reality, the strongest agency partnerships come from alignment.
Passion Digital helps businesses improve performance across multiple marketing channels.
Tenacious AI Marketing helps businesses become more visible across an evolving search ecosystem.
Both approaches have value.
The better choice depends on the challenge you are trying to solve.
If your focus is integrated digital growth, Passion Digital may be the stronger fit.
If your focus is discoverability, GEO, authority building and AI visibility, Tenacious may offer a more specialised approach.
As search continues to evolve, that distinction is only going to become more important.
