The Quick Comparison
In-House SEO
An in-house SEO function, even if it’s just a single person, offers full control and brand alignment. But the cost of that gets complicated, quickly.
Base salary is just a part of that. Benefits, payroll taxes, tools like Ahrefs or SEMrush push the true cost 20-35% above base. A mid-level SEO manager earning $70,000 realistically costs $85,000–$95,000 per year. Teams looking to create a substantial SEO function, content writers, technical specialists, analysts, quickly compound to over $200,000.
When in-house makes sense: You have a consistent, high volume of SEO work, need someone embedded in product and content strategy, and can support the full salary and benefits load year-round.
When it's a challenge: If your SEO needs fluctuate by campaign or season, you're carrying a full salary through slow months. And if a key team member leaves, the knowledge gap is immediate.
Agency SEO
Agencies offer a full team under a single retainer, a strategist, writers, specialists, reporting arm. The trade-off? Less control and a pricing structure that can balloon.
Retainer costs vary widely by agency tier and service depth:
- Entry-level retainers: $1,500–$3,000/month
- Mid-market agencies: $3,000–$8,000/month
- Enterprise-level or full-service SEO: $10,000–$20,000/month
Teams that want to outsource SEO entirely are intrigued by agencies that promise to handle everything. But, pricing assumes ongoing scope, and expanding deliverables dries the monthly number up quickly.
When agencies make sense: Large-scale projects, new market entry, or teams with no internal SEO resources who need a full-service partner.
When it's a challenge: Agencies manage multiple clients. Communication can lag, strategy can feel templated, and at lower price points, quality varies significantly.
AI-Run SEO Agencies
The AI-agency model has gotten attention for a lower price point, average around $3,200/month, undercutting the traditional retainer.
But the trade-off is real: automated content still skews generic, strategic thinking is thinner, and search engines have grown sophisticated at deprioritizing low-quality AI output.
This model might work for a team on a smaller budget simply needing content generation, but requires more judgement on quality and brand alignment.
Contractor / Freelance SEO
Freelancers are the most flexible option, hired for a sprint, a specific skill, or a project with a defined end date. The tricky part, is the seo specialist cost on a freelance basis swings wide based on experience, specialization, and platform:
Typical hourly rates:
- Junior: $25–$50/hour
- Mid-Level: $50–$100/hour
- Senior / Specialized: $100–$200/hour
Platforms like Upwork and Fiverr skew lower, often $15–$35/hour, but the price will correlate to level of output. On the other hand, experienced season freelancers who can run a full audit, develop keyword strategy, and manage migrations land in the $75-150/hour range.
When contractors make sense: Technical SEO audits, one-time content strategies, or campaigns that need specialized expertise your team doesn't have in-house on an ongoing basis.
When it's a challenge: Freelancers juggle multiple clients. Deadlines slip. Availability isn't guaranteed. And if the fit doesn't work, you're restarting the vetting process from scratch, which costs its own kind of time.
Offshore SEO (Full-Time)
This is the model most growth-stage teams underutilize.
With an offshoring partner like GrowthAssistant, you get a full-time, dedicated SEO Specialist at a flat monthly rate.
The SEO Specialist cost offshore typically looks like this:
- Junior: $3,500/month
- Mid-Level: $4,000/month
- Senior / Lead: $4,500/month
That rate covers sourcing, vetting, payroll, and benefits.
SEO Specialist salaries in the Philippines reflect these figures, mid-level specialists with 3-7 years of experience (the best fit for most growing brands) land around $4,000/month. That’s roughly half the cost of a US-based mid-level hire at $85,000/year.
When offshore makes sense: Growth-stage teams that need consistent full-time SEO execution: content optimization, keyword research, performance analysis, technical audits, but can't justify US salaries. If SEO needs to flex up or scale down seasonally, offshore is a great option.
When it's a challenge: Like any hire, success depends on clear and strategic goals that can be executed. That means SOPs, structured onboarding, and consistent check-ins.
How to Choose the Right Model
There's no universal right answer. The right answer depends on volume, budget, and how embedded SEO needs to be in your team.
Choose in-house if you have a large, steady workload, the budget to carry full salary and benefits, and need someone contributing to content and product strategy.
Choose an agency if you want to fully outsource SEO without managing individual contributors, have a larger budget, and need a team that can handle technical, content, and link-building simultaneously.
Choose a contractor if you have a defined project: an audit, a migration, a content strategy sprint and don't need ongoing availability.
Choose offshore if you need full-time SEO capacity at a lower cost with month-to-month flexibility. If you're building a marketing team on a budget, an offshore SEO Specialist is often the first hire that makes the math work.
SEO isn't where you cut corners, but it is where you can be smart about fractional marketing services and the models available to you.
The difference between a $200K/year in-house team and a $48K/year offshore specialist isn't always quality. Often, it's just the model.
