SEO can feel bewildering.
First, it’s not clear what information about SEO is accurate or totally BS. There’s a lot of noise, little signal.
Second, SEO is changing all the time. Of course, AI search and answer engine optimization is shaking stuff up, not to mention your regular Google algorithm updates.
How’s a brand supposed to make any progress in such a cacophonous world?
A smart play may be to bring in a knowledgeable and steady-handed SEO consultant.
Unlike an agency, an SEO consultant can embed themselves within your organization, effectuating not only nominal changes to your sitemap or internal linking structure, but to your team structure and marketing channel mix.
In a word, they can bring clarity to your organic growth program.
It’s a good time to hire an SEO consultant, because many talented and experienced professionals are striking off on their own. So there are many options.
I wanted to put together a handful of the top SEO consultants to help companies choose. Feel free to email me (you can find it easily) if you need more recommendations or have questions about this. I place a lot of consultants at companies due to my work.

Hi, I’m Alex Birkett.
I take only one very special client at a time and embed myself as a strategic growth advisor and consultant, focusing on organic growth and driving revenue outcomes.
I’ve worked on growth and experimentation at companies like HubSpot and Workato, and I’ve helped brands like LinkedIn, SAP, Jasper, TikTok, Gable, and Mutiny grow through SEO, conversion rate optimization, analytics and experimentation, and growth marketing.
Due to my demanding role growing Omniscient, I work only with brands that I confidently believe I can take from one to 1,000 with my unique skillset and industry expertise (B2B SaaS scale-ups and enterprises).

How to Choose an SEO Consultant
Hiring an SEO consultant isn’t just about finding someone who can “do keywords.” It’s about finding a partner who can embed themselves in your business, understand your incentives, and navigate the ambiguity that defines organic growth.
Much of your decision process will be personal, custom, and suited to your specific needs, budget, and timelines. I think these four dimensions are good ways to anchor your decision:
Industry Focus & Depth
Every industry has its own search language.
The tactics that drive conversions for a SaaS company are wildly different from those for an eCommerce brand or media site. Look for someone who’s worked with businesses like yours — ideally with a proven record in your category. Generalists can be great, but specialization compounds results faster. Additionally, search is but a distribution channel to deliver your message, product, content, and voice to the end user who is searching for a solution to their problems.
Thus, it helps to have someone who understands the business model, go-to-market model, and how to integrate search into this model.
Level of Engagement Needed
Some consultants operate like coaches, offering strategic guidance, frameworks, and playbooks your team executes. Others go hands-on, embedding directly into your systems and team workflows.
Some will be highly specialized in a given area of SEO, such as technical SEO or content strategy. Otherwise will take a broader view of growth or marketing with an eye towards organic channels and search.
Decide whether you need an architect or a builder, a growth advisor or a technical SEO specialist, and choose accordingly.
Cost
Good SEO consultants aren’t cheap, and they shouldn’t be. You’re paying for years of pattern recognition, the ability to spot what actually moves the needle and what’s just noise. You’re also often paying for network, connections, and frameworks, all of which massively increase time to value.
Expect to invest anywhere from $5,000 to $25,000 per month depending on engagement depth and consultant reputation.
Reputation
SEO is a noisy field. Everyone has a hot take and a case study. The best consultants are those who’ve earned trust through substance: they write, publish, speak, and teach. They’ve done the work in-house, led teams, or built their own growth engines. Their reputation isn’t built on bravado, or god forbid, being a LinkedIn thought leader.
It’s built on results and clarity of thought. Sometimes the best consultants are the quietest (you know what Lil Wayne said).
Conclusion
SEO can feel chaotic, like a blur of updates, opinions, and shifting algorithms. A great consultant brings order to that chaos. They see the patterns, connect the dots, and help your team focus on the work that compounds.
The right partner won’t just grow your traffic; they’ll change how you think about growth itself.
