SEO Consultant vs SEO Agency · From Someone Who Has Worked in Both
SEO Consultant vs Agency. Which One Fits You?
I spent three years inside an agency running SEO and site operations for 20+ client accounts, and I own one now: Zozzah, where I work hands-on with my team. I have seen the agency model from both sides. Agencies and consultants both work, for different businesses at different budgets, and this page shows you how to tell which one fits yours.
The Short Answer
SEO consultant vs agency: pick by the work you need done.
Hire an SEO consultant when your problem needs senior judgment on a site one person can own. Working out why you don't rank, fixing the technical issues behind it and deciding which pages to build is consultant work, and it covers most service businesses and B2B firms. Most will fit here.
Hire an SEO agency when you need volume every month: dozens of articles, outreach at scale, or design and development running in parallel across several sites or markets. Teams do that well.
Build in-house when search sits at the center of how you make money and the work never runs out. Plan for a full salary plus tools, and expect to bring in outside help for specialist problems.
Side by Side
How agencies and consultants compare.
| What to compare | SEO Agency | SEO Consultant |
|---|---|---|
| Who does the work | Team Strategy, writing, links and development are split across specialists, usually coordinated by an account manager. | One senior person One person audits, plans and does most of the hands-on work, and some bring in help for design or development, so ask who does what. |
| Average cost | Survey data $3,209 a month on retainer, $98.90 an hour, or $9,508 per project. | Survey data $171.18 an hour, the highest of any group surveyed. Consultancies average $8,686 per project. |
| Main strength | Capacity Content, links, design and development run at the same time, every month. | Depth The person who diagnoses the problem is the person who fixes it. |
| What to watch for | Split attention Ask who works on your account each week and how many other accounts they carry. | Limited capacity Ask what happens when you need more hands, or when the consultant is unavailable. |
| Best for | Volume Large or content-heavy sites, several markets at once, and teams that want a managed production line. | Focus Service businesses and B2B firms with a focused site, where the hard part is knowing what to fix. |
Cost figures are averages from the Ahrefs survey of 439 SEO providers. Your own quotes will vary with scope and market.
The Third Option
What hiring an in-house SEO costs.
The median US salary for a search marketing strategist is $78,760 a year, according to the Bureau of Labor Statistics (May 2025), and benefits, payroll taxes and SEO tools come on top of that.
In-house pays off when search work never runs out and someone has to own it every day, like a store with thousands of product pages. A service business with a 30-page site usually runs out of high-value SEO work for a full-time hire well before the year is over.
One hire also won't cover every skill. Technical SEO, content, link building and analytics are different jobs, so most in-house teams still pay for outside help on the hard problems.
From Inside an Agency
What three years of agency work taught me.
At 3Kings Media House I ran website operations and SEO across 20+ client accounts and 50+ websites, turning client requests into tasks for developers, designers and writers.
That is the agency model working well. One request becomes coordinated work across several specialists in the same week, and routine updates, migrations and fixes ship on schedule.
The trade-off shows up when a site has a problem nobody has diagnosed yet, because with one person's week split across 20 accounts, the work follows the process. Finding a hidden problem takes slow, focused attention on one site. That is why I stay hands-on in every Zozzah account.
Questions to ask before you hire either one.
- Who works on my site each week, by name?
- How many other accounts does that person handle right now?
- What will you deliver in the first 90 days, in writing?
- How will we measure success: rankings, leads or revenue?
- Can I see a case study with a named client I can check?
- If we stop working together, do I keep the content, accounts and data?
How I Work
What you get when you hire me.
I do the work with my team.
The audit, the strategy and the technical SEO are mine, and I work hands-on with my Zozzah team on the build. You will know who is doing what at every stage.
We measure leads and revenue.
Every engagement starts with tracking, so we count enquiries and contracts as well as rankings, which for Joint Power Security came to 3,000+ inbound enquiries and $600K+ in contracts won over 18 months.
Most of the work stays in-house.
Design, development, content and SEO happen inside Zozzah, so your project is not passed to contractors you have never met. If it needs more than we deliver, the free audit says so.
Clients
