_The title is clickbait. The advice is not._
Every year, agencies publish a list of the “Top 10 Enterprise SEO Agencies.” And every year, enterprise leaders skim it, read a few highlights, and end up disappointed down the line after choosing the wrong one.
The truth is that the best enterprise SEO agency isn’t one that’s universal — it’s contextual. There is no absolute solution, and a top 10 list of the best agencies around isn’t going to give you what you need to identify the right partnership. The key is determining which agency will provide the best solution for _your_ business model, goals, and unique challenges. That’s how you really find the “best” SEO agency. That’s how you get the results you want.
Fit matters more than fame. Thinking matters more than tactics. People matter more than promises. So instead of pretending there’s a magical solution out there waiting to be discovered, this article gives you something far more useful:
The 10 criteria that actually determine whether an SEO agency will succeed inside your organization.
We’ve organized the criteria into four key areas: understanding your business needs and internal teams, evaluating agency capabilities and track record, assessing operational fit, and focusing on the right people. Together, these categories guide you through a complete evaluation process. We’ve also included a quick list of agencies and strategic consultants to help guide you toward the right fit.
Let’s get started.

Best Agency for Fit
1\. Start With the Real Need
Most failed engagements start with a vague mandate like “we need SEO help” or “I was told to find an SEO agency.” Neither of these clarifies why you’re looking for a partner or what success should look like.
Before considering an SEO agency partnership, you need to get brutally honest about _why_ you need one. Many organizations hire SEO agencies because they recognize that “someone needs to own SEO,” but what they often overlook is that search engine optimization isn’t a monolith — it’s a set of interconnected disciplines that solve different problems across growth, visibility, and performance.
That means you must clearly define what you actually need help with. This responsibility sits with the primary stakeholders and the teams who will work most closely with the agency — not with an executive mandate or an outside recommendation.
So, what are you looking for?
Ultimately, a solid needs assessment will answer these questions:
Rule of thumb: If you can’t articulate the need, no agency can help you.

2\. Know Your Skills Gap: Strategy or Execution?
Many enterprises hire agencies to do the _wrong_ job. The most common point of failure has nothing to do with an agency’s performance but a lack of clarity around your own team’s capabilities and limitations. If you don’t understand where your internal skills break down, no agency will be able to fill the gap effectively.
Here’s what you need to consider:
Some SEO agencies excel at executive-level strategy but struggle with execution. Others are exceptional operators, but shouldn’t be setting your roadmap. Very few can do both well.
Additionally, if you didn’t clearly define your need, you’ll never accurately identify the skills gap. In many cases, that gap is purely strategic. There are outstanding strategic leaders in the industry, including Britney Muller, Eli Schwartz, and Kevin Indig, who offer high-impact thinking without execution overhead. If that’s what you need, hire for it explicitly.
Misalignment here is one of the fastest ways to burn budget and goodwill.
3\. Define How Internal Teams Will Actually Partner
Organic growth does not succeed in isolation. It’s inherently co-dependent, and failure is often less about execution and more about misalignment between teams. Success now depends on how SEO partners with product, engineering, content, analytics, and PR. If those relationships aren’t defined early, progress slows and accountability breaks down.
Before signing a contract, get explicit clarity on:
If your internal teams treat the agency as an external task rabbit, results will stall. When agencies are embedded as true partners, you’ll see better alignment, improved execution, and stronger business outcomes.
Agencies like Always Onward (Jerry Smith) and Seer Interactive are strong examples of this approach. They integrate deeply with internal teams, engage directly in data and reporting, and push adjacent functions like PR to raise their game. That level of partnership is what drives durable organic growth.
How to Evaluate Agency Fit
4\. Evaluate How They Think, Not Just What They Promise
Any agency can promise traffic growth. In fact, most will promise a lot. Unfortunately, those promises are often based on zero context about your business, your customers, and your goals.
What you really need is a thought partner — someone who can explore and define your business needs, connect those to user behavior, and translate them into web experiences that drive real value. That’s the true promise of a great agency partnership.
Ask them to walk you through:
Red flags: Tactical answers that lack strategic context. Focusing on features instead of the customers’ needs. You’ll end up with traffic but no real customer value.
Green flags: Clear alignment with your users and customers. Thoughtful discussions on trade-offs and planning. Acknowledgment of uncertainty at the start of the partnership, with a plan to adapt as you go.
Example: Joy Hawkins from Sterling Sky excels at aligning her team with small business customer needs. Steve Toth from SEO Notebook has a laser-sharp focus on B2B success. That kind of clarity and focus is invaluable.
5\. Request Proof of Impact in Similar Situations
Stop relying on prebuilt case studies. They’re just marketing fluff without any real context.
Case studies should demonstrate _judgment_, not just results. When evaluating an agency, ask them to explain how they’ve handled situations similar to yours. Look for answers that align with your resources, challenges, and target customers.
This means pushing past vanity metrics and asking:
Remember: Similarity matters more than scale. A win at a company that mirrors yours is far more valuable than a big-name logo that doesn’t align with your needs.
Look for partners with a deep understanding of your customer profile, and prioritize that over generic expertise or a shiny reputation. This is why founder-led agencies often outperform others. Founders bring a personal proof of concept and experience that few employees can replicate. However, agencies like iPullRank and Siege Media have scaled while maintaining strong connections to their customer bases.
6\. Pressure-Test Fit Through References
References are only useful if you ask the right questions. Most team leaders don’t.
If you’re asking surface-level questions like “Did you enjoy working with them?”, “Did they deliver results?”, or “Would you hire them again for the same problem?”, you’re wasting the opportunity. In most cases, former clients will offer those answers without being asked anyway.
At this stage, the goal is to validate partnership behavior — not basic competence. Come prepared with a clear script and focus on getting answers regarding how the agency actually operates inside complex organizations.
Ask former clients:
Remember: You’re not evaluating success in isolation. You’re assessing effort, judgment, adaptability, and working style. Strong references should give you a clear picture of how the agency behaves when things get difficult — because in SEO, they always do.
Critical Considerations Most Teams Miss
7\. Define Communication Styles Early
Miscommunication kills enterprise SEO faster than bad strategy.
Details like meeting cadence, deliverables, and reporting formats are important, as they keep work on track and ensure visibility and consistency. But even when those are managed well, misalignment in how decisions are made, documented, and communicated across the organization remains a significant risk.
The key question to answer before the engagement starts is: “At our company, this is how we communicate and make decisions. How will you operate within that environment?”
To avoid friction later, align early on:
Strong agencies adapt their communication style to your culture — not the other way around. But that only works if you clearly define how your organization operates. As the owner of the relationship, it’s your responsibility to set expectations and ensure follow-through.
8\. Set Expectations Around Access and Data
SEO cannot operate blind. Limited access to tools, data, or internal systems is one of the most common — and avoidable — causes of underperforming agency relationships.
Before you start the engagement, align on what access the agency needs to be effective. Without it, frustration mounts, timelines slip, and results fail to meet expectations.
Key areas to clarify upfront:
Limited access is a red flag on _your_ part. If your team cannot provide the tools, data, and internal alignment a full-service execution engagement requires, the agency cannot deliver meaningful results. In this case, a strategic advisor is often a better fit, as they can provide guidance and strategy without requiring full operational support.
9\. Invest Time in Educating the Agency on Your Business
The best SEO agencies don’t “just figure it out” on their own. They deliver meaningful results through active education and context. The more they understand about your business, the faster and more effectively they can drive impact.
Giving them product briefs, customer research, analytics reports, and internal process documentation is only the starting point.
The key areas to cover for success include:
This education should be ongoing as these key areas evolve. Continuous engagement and context-sharing accelerate results, reduce missteps, and ensure recommendations are realistic. It’s your team’s responsibility to provide the agency with the necessary context and guidance to operate effectively within your organization.
Remember: Enterprise SEO is not plug-and-play. Providing context, guidance, and insight ensures the agency can operate effectively as an extension of your team, collaborating with you to deliver meaningful, sustained impact.
10\. Focus on the People (This Is What Matters Most)
Here’s the uncomfortable truth that no “Top 10” list will ever tell you: the individuals doing the work matter far more than the agency brand or reputation.
Talent, curiosity, accountability, and a genuine willingness to collaborate will outperform reputation, accolades, or any “Top 10” badge. Even the most decorated agency can underperform if the team you work with isn’t aligned with your goals, ways of working, and organizational culture.
Before evaluating the agency team, take a moment to assess your own organization:
Answering these questions ensures that your internal capabilities and constraints are clear, which in turn allows the agency to operate effectively and deliver real impact.
When evaluating the SEO agency team, ask yourself:
Remember: Fit, alignment, and mutual trust drive real results. If you trust the team, respect how they think, and enjoy working with them, you’ve likely found the agency that will deliver strategic clarity, operational impact, and outcomes that truly matter. And _that_ is what makes them the best.
