Best SEO consultants in 2026: 12 ranked

For most companies the constraint is execution rather than advice, which is why theStacc ranks first here at $749 a month. Among individual consultants, Aleyda Solís is the global reference for multi-market SEO, Kevin Indig for tech growth and Marie Haynes for core-update recovery. We ranked 12 on specialism, track record and availability.

How we ranked these

Our criteria — and why they matter

Consultants cannot be scored the way software can, so we scored the evidence. For each name we read the public body of work — original research, tests, talks, books and newsletters — and weighted first-hand experimentation above commentary. We logged the specific specialism each one is genuinely the best answer for, whether the engagement produces a diagnosis, a strategy or ongoing advice, how obtainable their time actually is, and whether any implementation is included. That last column is empty for almost everyone here, which is the honest headline of this list.

Each company is scored on five weighted factors:

Results & traffic (30%) — measured organic sessions and ranking footprint · Output & value (25%) — content shipped per dollar, contract terms · Technical & AI-search (20%) — site performance, schema, AI-citation rate · Transparency (15%) — public pricing, honest reporting · Fit & specialization (10%) — depth in your niche.

Every consultant on this page is worth their fee for the right problem, and none of them will publish a page for you. That is not a criticism; it is the definition of the role. The failure mode is predictable — a company pays for a superb strategy, the document lands in a shared drive, and eight months later nothing on the site has changed. theStacc places first because it is the missing half: 30+ pages published every month with a human SEO manager reviewing each one. Buy the diagnosis from a specialist. Buy the capacity to act on it separately. If you want a company rather than an individual, the SEO company ranking is the better list, and managed SEO describes the execution half in detail.

The ranking

12 SEO consultants, ranked

#1 · Best overall

theStacc

AI SEO engine with a human SEO team · from $749/mo · month-to-month

theStacc is on this list because most companies searching for an SEO consultant do not actually have a knowledge problem. They know their site is thin, their profile is neglected and nothing has been published since spring. What they lack is someone to do it every week. theStacc publishes 30+ pages a month to your site — service pages, comparison pages, question pages, location pages — each reviewed by a human SEO manager before it goes live, all built to rank in Google and be cited across AI search engines. From $749/mo, month-to-month, and every page belongs to you. If your problem genuinely is diagnostic — a core update loss, an international architecture, a technical retrieval issue — hire one of the eleven specialists below first, then come back for the execution.

Strengths

  • 30+ pages published a month, not a document with recommendations
  • Human SEO manager reviews every page before publishing
  • Built to rank in Google and be cited across AI search engines
  • From $749/mo, month-to-month, content stays yours

Good to know

  • Runs alongside a consultant engagement without overlap
  • Starts producing in the first month, not after a discovery phase

Aleyda Solís (Orainti)

International, ecommerce and SaaS SEO · custom pricing

The reference point for international SEO, full stop. If your problem involves hreflang, multi-market architecture, marketplace structure or migrating a site across dozens of country variants, there is no stronger single brain available, and the SEOFOMO newsletter has made her thinking public enough that you know exactly what you are buying. Orainti is a boutique consultancy, so availability is genuinely scarce, engagements are advisory, and nobody is going to implement the recommendations for you.

Strengths

  • The global authority on international and multi-market SEO
  • Deep ecommerce, marketplace and SaaS experience
  • Public body of work you can evaluate before hiring

Consider

  • Very limited availability
  • Advisory only — no implementation capacity
Pricing: Custom (boutique consultancy)Best for: International and multi-market SEO

theStacc vs Aleyda Solís (Orainti): theStacc executes the publishing programme a consultant of this calibre would specify.

Kevin Indig

Growth advisory for scaled tech companies · custom pricing

A growth advisor who has run search at Shopify, Atlassian and G2, which means the advice arrives already tested against the constraints of a large product organisation — engineering roadmaps, competing priorities, and internal politics that kill more SEO projects than Google ever has. Best used as a strategic advisor to a growth or SEO lead who already has a team. Advisory retainers are priced accordingly and there is no execution attached.

Strengths

  • Operator experience inside major tech companies
  • Excellent at organisational and roadmap constraints
  • Strong on growth modelling and prioritisation

Consider

  • Advisory only, priced at operator-advisor rates
  • Assumes you have a team to execute
Pricing: Custom (advisory retainer)Best for: Scaled tech growth strategy

theStacc vs Kevin Indig: theStacc is the execution capacity that an advisory retainer explicitly does not include.

Eli Schwartz

Product-led SEO strategy · custom pricing

The author of Product Led SEO, and the consultant to call when the honest answer might be that you should not be publishing more articles at all. His framing starts from what the product does and who buys it, then works out which search demand is worth capturing — which routinely saves companies from a content calendar that was never going to convert. Strategy engagements are senior and finite, and implementation stays entirely with your team.

Strengths

  • Product-first framing that avoids wasted content programmes
  • Strong on measuring SEO against business outcomes
  • Well-documented public methodology

Consider

  • Strategy engagements only
  • Your team carries all execution
Pricing: CustomBest for: Product-led SEO strategy

theStacc vs Eli Schwartz: theStacc publishes against the strategy once someone has decided what is worth publishing.

Marie Haynes

Algorithm recovery and quality signals · custom pricing

The most trusted diagnostician for sites that have lost traffic to a core or spam update, with a body of work on quality signals and search-quality guidelines that predates most of the industry's interest in the subject. When traffic halves overnight and nobody can explain why, this is the analysis worth paying for. Recovery work is inherently uncertain, nobody can promise reversal, and the deliverable is a diagnosis rather than a fix.

Strengths

  • The strongest algorithm-recovery diagnostic work available
  • Deep grounding in quality raters and search guidelines
  • Rigorous, evidence-led analysis

Consider

  • Recovery outcomes are never guaranteed
  • Diagnosis, not implementation
Pricing: CustomBest for: Core update recovery

theStacc vs Marie Haynes: theStacc rebuilds published depth after a diagnosis identifies what was missing.

Cyrus Shepard (Zyppy)

Testing-led on-page SEO · custom pricing

Runs actual experiments and publishes the results — title tag studies, click-through research, internal linking tests — which puts the recommendations on firmer ground than almost anyone else's opinion. If your site is large enough that a one-percent click-through improvement is real money, this is high-leverage work. It is deliberately narrow: on-page and technical testing rather than a full growth programme, and it needs a site with enough traffic for the tests to be meaningful.

Strengths

  • Recommendations grounded in published experiments
  • Excellent on titles, click-through and internal linking
  • High leverage on large sites

Consider

  • Narrow focus, not a full programme
  • Needs meaningful existing traffic
Pricing: CustomBest for: Testing-led on-page gains

theStacc vs Cyrus Shepard (Zyppy): theStacc adds the page volume that on-page testing needs in order to matter.

Michael King (iPullRank)

Technical and AI search consultancy · custom pricing

The strongest technical and information-retrieval thinking in the field, now applied heavily to how AI search systems select and cite sources — genuinely ahead of the market on that question rather than repackaging it. Best suited to complex enterprise sites where the problem is architecture, rendering or retrieval rather than a shortage of pages. It is consultancy-priced, and the depth is wasted on a straightforward site.

Strengths

  • Exceptional technical and information-retrieval depth
  • Ahead of the field on AI search and retrieval
  • Enterprise-grade engineering fluency

Consider

  • Consultancy pricing
  • Overkill for simple sites
Pricing: Custom (consultancy)Best for: Complex technical and AI search

theStacc vs Michael King (iPullRank): theStacc handles the ongoing publishing once the technical foundation is sound.

Tom Critchlow

Independent strategy consulting · custom pricing

Works on the layer above tactics: how a content or search programme should be structured inside a company, who owns it, how it gets funded, and why the last three attempts stalled. For organisations where the SEO problem is really an operating-model problem, that reframing is worth more than another audit. It is also abstract by nature, and a business that simply needs more pages published will find the engagement frustrating.

Strengths

  • Strong on operating models and internal ownership
  • Reframes stalled programmes usefully
  • Senior, independent perspective

Consider

  • Strategic and abstract by design
  • No tactical or execution output
Pricing: CustomBest for: Fixing how SEO is run internally

theStacc vs Tom Critchlow: theStacc is the delivery arm that makes a newly agreed operating model actually produce something.

Glen Allsopp (Detailed)

Competitive and industry analysis · custom pricing

Publishes some of the most useful competitive research in the industry — which companies quietly own entire verticals, how large media groups monetise their domains, where the real leverage sits in a niche. Reading the analysis often changes strategy more than a consulting call would. Availability for private work is limited, the strength is analysis rather than implementation, and the insight is most valuable for publishers and affiliates.

Strengths

  • Unusually sharp competitive and vertical analysis
  • Reveals leverage most audits never find
  • Substantial public track record

Consider

  • Limited availability for private engagements
  • Publisher and affiliate slant
Pricing: CustomBest for: Competitive vertical analysis

theStacc vs Glen Allsopp (Detailed): theStacc turns a competitive gap analysis into pages published every week.

Bastian Grimm (Peak Ace)

Technical SEO and performance · custom pricing

European technical SEO depth, particularly on site performance, crawling and large-scale international infrastructure, backed by an agency team that can carry a long engagement. A strong choice for a large European site with a complicated technical stack and multiple language versions. This sits closer to agency than solo consultant, with the pricing and process that implies.

Strengths

  • Deep technical and performance expertise
  • Agency team behind the named consultant
  • Strong European and multi-language coverage

Consider

  • Agency structure and pricing
  • Less focus on content programmes
Pricing: CustomBest for: Technical SEO at European scale

theStacc vs Bastian Grimm (Peak Ace): theStacc supplies content volume in the languages a technical fix makes crawlable.

Nick Eubanks

SEO strategy and content operations · custom pricing

Comes at SEO from a business-model angle, with real experience buying, growing and selling content sites, which shows in how he prices opportunity — what a keyword set is worth in revenue rather than in traffic. Practical, commercially minded advice for founders. The consulting is senior-led and finite, and the operational build-out remains yours to staff.

Strengths

  • Values opportunities in revenue, not traffic
  • Real operator experience with content assets
  • Commercially practical for founders

Consider

  • Advisory scope, finite engagements
  • You staff the operational build-out
Pricing: CustomBest for: Commercial SEO opportunity sizing

theStacc vs Nick Eubanks: theStacc is the operational build-out the opportunity model assumes will happen.

Dan Shure (Evolving SEO)

Independent consulting and audits · custom pricing

A long-established independent consultant known for careful, thorough audits and unusually clear explanations — the kind of deliverable a non-technical founder can read and act on without a translator. Good value for a small or mid-sized site that needs one senior opinion rather than a retainer. Solo capacity means limited availability and no ongoing production of any kind.

Strengths

  • Exceptionally clear, actionable audits
  • Senior attention on smaller sites
  • Independent, no upsell agenda

Consider

  • Solo capacity, limited availability
  • One-off audits, no ongoing work
Pricing: CustomBest for: A clear senior audit

theStacc vs Dan Shure (Evolving SEO): theStacc does the work the audit recommends, every week, without another engagement.

We don't ask you to trust us. We show you the data.

Advice is judged on how smart it sounds. Publishing is judged on what shows up in Search Console. Here is what continuous publishing does across SEO, GEO and AEO on client accounts and our own site.

Why SEO feels slow and expensive

SEO shouldn't be limited by your team's capacity.

A freelancer gives you five posts a month. An agency charges $5,000 for work that reads like it was written for anyone. Hire in-house and you're training someone for months. They all hit the same wall — there are only so many hours in a day.

The difference

An SEO engine with a team on top. Not another agency.

Agencies sell you hours, so wanting more means paying more. We spent years learning how Google — and now AI — decide who ranks. Then we built software that does that work on repeat. It doesn't get sick, distracted or bored, and a real SEO manager owns your results.

Step 1 · Research

We work out what your customers search for

The engine reads the keywords, the questions people ask, and what your competitors already rank for. It covers more ground in a day than one person could in a month.

Step 2 · Publishing

We turn it into pages and post them

All of that research becomes real content, written in your voice, and published to your website, blog, Google listing and social accounts. Every week, without you asking.

Step 3 · The team

Real people check the work

You get an SEO manager who owns your strategy, reads what goes out, and walks you through it once a month. The software does the volume. People decide what good looks like.

The result

30+ pages a month, month after month

An agency sends you five or six blogs. We publish more than thirty, all researched, all optimized, all live. And because it never stops, the results build on each other.

Buyer's guide

How to choose an SEO consultant

Six things that separate a partner that compounds from a retainer that drains. Take them into every sales call.

01

Match the model to your size

Enterprise brands can absorb a $10k/mo retainer; a small business or a Series-A startup usually can't and shouldn't. Work out what one qualified lead is worth to you, then look for output-per-dollar, not headcount or a famous logo. A team of 40 doesn't help if only two of them touch your account.

02

Insist on transparent pricing and month-to-month terms

A 12-month lock-in protects the agency, not you. If a company needs three calls before it will name a price, that opacity is the product. The best partners publish what they cost and earn the next month every month — so the pressure to perform stays on them, where it belongs.

03

Ask how they handle AI search (GEO + AEO)

More buyers now ask ChatGPT, Gemini and Perplexity "who's the best…" before they ever open Google, then read the answer box without clicking. If a company can only talk about blue-link rankings and can't explain how it gets you named by AI engines, it's already a year behind — and so are you if you hire them.

04

Check who actually does the work

"AI-powered" should mean an engine that multiplies a real team's output — not a black box that publishes unreviewed, and not a team so small it caps at six posts a month. Ask who writes, who reviews, and what happens before anything goes live on your domain. The right answer is: software for volume, humans for judgment.

05

Demand proof on real sites, not logos

A wall of client logos proves someone paid an invoice, not that rankings moved. Ask for two or three live URLs and their actual Search Console or Semrush growth. A company confident in its work will show you the graphs; one that isn't will show you a testimonial carousel.

06

Read the contract for who owns the content

Some agencies host your content on their platform and take it down the day you leave, so cancelling means losing everything you paid for. Confirm in writing that every page published to your site stays yours, forever, with no clawback. If they hesitate, that tells you how the relationship ends.

On the call

Questions to ask before you sign.

Copy these into your notes. The answers tell you more than any pitch deck.

  • Can I see three live client sites and their real ranking growth?
  • Exactly what gets published each month, and who reviews it before it goes live?
  • How do you get me cited by ChatGPT, Perplexity and Google AI Overviews?
  • What's the minimum term — and what happens to my content if I leave?
  • Who is my point of contact, and how often do we actually talk?
  • How do you measure success: rankings, traffic, or booked leads?
  • How fast does the first work go live after I sign?
  • Is pricing fixed, or does "more output" always mean "more money"?
Walk away if…

Six red flags that cost you a year.

Any one of these on a sales call is reason enough to keep looking.

  • A 12-month lock-in demanded before you've seen a single result.
  • No named clients or live examples you can independently verify.
  • "AI-powered" with no human reviewing what publishes on your domain.
  • Vague, custom-only pricing that takes three calls to pin down.
  • Reporting you have to chase, in a format you can't act on.
  • No real answer for how they handle AI search in 2026.
Questions

SEO consultants, FAQ

When should you hire an SEO consultant?

When you have a problem you cannot name. Traffic fell and nobody knows why. A migration is coming and getting it wrong would be catastrophic. You are entering six countries and the architecture has to be right the first time. In those situations senior judgement is cheap relative to the mistake. If your diagnosis is simply that you publish nothing, a consultant will confirm it and charge you for the confirmation.

Why do consultants not implement?

Because implementation is a different business with different economics. Advisory work scales on one person's judgement; production scales on headcount and process. Consultants who take on delivery usually become agencies, and the ones on this list have deliberately chosen not to. Plan for it: budget the execution separately at the same time you budget the advice.

What should a consulting engagement produce?

Three things you can act on: a ranked list of problems with the biggest first, a specific recommendation for each, and an owner and rough effort estimate for every item. If a deliverable arrives as a hundred-page audit with no prioritisation, it will not get implemented — not because it is wrong, but because nobody knows where to start on a Monday morning.

How do you check a consultant is worth the money?

Read their published work before the first call. The best names in this field have years of visible thinking — tests, talks, newsletters, books — and you can judge the quality directly rather than relying on a case study you cannot verify. Then ask for one specific opinion about your site on the call. Specialists give you something useful in ten minutes; generalists ask for an audit first.

Can software replace a consultant?

For judgement, no, and we would not claim otherwise. For production, mostly yes — writing, publishing, internal linking, profile posts and review replies are repeatable work that a system with human review does more consistently than a person doing it between meetings. Use both: a specialist for the hard questions, and theStacc's content engine for the weekly output.
