An SEO consultant typically works solo, charging $80–$250/hour for advisory and execution work. An SEO agency typically has a team of 5–50 people, charging $2,500–$10,000/month for retainers. Both can deliver good outcomes; both can deliver bad ones. The right choice depends on your business size, internal SEO capability, and what you actually need delivered.

This guide covers the real differences and how to decide.

When a consultant is the right fit

Hire an SEO consultant when:

You have someone in-house who can execute. The consultant guides; your team does the work. A marketing manager + senior consultant beats most agencies for capable in-house teams.

You need specialist expertise. Technical SEO migrations, schema architecture, AEO strategy, recovery from a Google penalty — these are specialist skills where the right consultant outperforms a generalist agency.

Your scope is project-based. One-off audits, migrations, technical reviews are well-suited to consultants who price by project rather than ongoing retainer.

Your budget can't reach $2,500/month. Below that threshold, agency work is usually under-resourced. A senior consultant at 5–10 hours/month often outperforms a $1,500/month agency.

When an agency is the right fit

Hire an SEO agency when:

You don't have in-house SEO capability. The agency handles strategy, content, technical, links, and reporting end-to-end. You provide direction; they handle execution.

The scope spans multiple disciplines. Real SEO covers technical, content, link building, and AEO. Few consultants are equally strong in all four. Agencies build teams that cover all four.

You need consistent monthly output. Agencies have project management, content production, and reporting infrastructure. Consultants often don't.

Accountability matters. Agencies have processes, reporting, and incentives to retain accounts. Consultants are individuals; their availability and attention can fluctuate.

The hybrid model

For many $5–10M businesses, the best fit is a hybrid: a strategic SEO consultant ($1,500–$3,000/month) plus an agency or in-house team handling execution. The consultant sets direction; the executors do the work; the consultant reviews quality and adjusts strategy.

This model gets you senior expertise without paying senior fees for execution work, plus execution capacity without paying agency markup on strategy.

Red flags for both

Warning signs that apply regardless of consultant or agency:

  • Promises of #1 rankings in 30 days
  • Bulk link building schemes or guest post networks
  • Vague reporting that doesn't tie to business outcomes
  • Long-term contracts with heavy cancellation penalties
  • No specific examples of work or named clients
  • Claims of "secret techniques" or "proprietary algorithms"
  • Pricing dramatically below market rate ($500/month) — usually means under-resourcing

What to ask in interviews

Five questions for both:

1. "What does the first 90 days look like specifically?" Vague answers are red flags.

2. "Show me a client whose traffic has grown for 3+ years." Long-term results are the only test.

3. "How do you handle AEO?" Modern SEO requires it. If they don't have an answer, they're behind.

4. "Who actually does the work?" Consultant: them, directly. Agency: get specific names. If a senior pitches and a junior delivers, beware.

5. "What's a project you turned down?" Tests judgement. Both consultants and agencies should have examples.

Goji's perspective

Goji is a full-service agency, but we work alongside consultants regularly — either consultants who refer clients to us for execution, or consultants who advise our clients in specialised areas. The honest answer to consultant vs agency is that neither is universally better. The right choice depends on what your business actually needs and what your in-house team can absorb.

Frequently asked questions

Can a consultant deliver as much as an agency?

For strategic guidance and specific projects, yes — often more, because consultants are typically more senior than the staff actually doing agency work. For ongoing execution across multiple disciplines, no — a single consultant has limited capacity.

Is hourly pricing better or worse than retainer?

Hourly works for project-based work where scope is clear. Retainer works for ongoing relationships where scope flexes. Hourly with no defined deliverables is a red flag — it incentivises stretching hours rather than delivering outcomes.

How do I find a good SEO consultant?

Three sources: industry referrals from people whose SEO is working, conference speaker lists (people who present on SEO usually do it well), and LinkedIn searches of senior SEO practitioners with verifiable experience. Avoid Upwork and similar platforms for senior SEO work — the quality bar is too low.

What's the typical commitment length for a consultant?

3–6 months minimum for ongoing work. Project work is shorter. Be cautious of consultants who don't want a minimum commitment — SEO takes time to compound, and rapid switching usually means the previous arrangement wasn't working.

Can I switch from consultant to agency (or vice versa)?

Yes, easily — SEO work doesn't lock you to a specific provider as long as you own the content, links, and access. The transition usually takes 4–8 weeks. Make sure documentation is good before switching.
