SaaS SEO agency vs in-house vs fractional: cost and fit
If nobody on your team works on search full time, an SEO and AEO agency is usually the cheaper and quicker way to start. An in-house hire wins once search is a core channel with a full-time workload, and a fractional lead suits a team that already has writers but lacks senior search judgement. On cost, the median US marketing specialist earned $78,760 in May 2025 and the median marketing manager $166,790, before benefits, according to Bureau of Labor Statistics data published on O*NET. The Rank Master, which publishes this page and is one of the agencies in this comparison, charges $24,000 to $78,000 a year across its three tiers, and the other agencies we checked that publish a price start at $3,500 to $10,000 a month.

The three options at a glance
| SEO and AEO agency | In-house hire | Fractional SEO lead | |
|---|---|---|---|
| Yearly cost | $24,000 to $78,000 at The Rank Master (custom from $18,000); other published entry prices from $3,500 to $10,000 a month | Median salary $78,760 for a specialist or $166,790 for a manager (US, May 2025) | No published rate we could check; priced person by person |
| On top of the fee | Whatever the contract leaves out: ask about writing, tools and developer time | Benefits (31.5% of compensation costs for full-time private-industry workers), plus tools, writers and developer time | Tools and all execution |
| Time to first output | Starts when the contract does; The Rank Master counts deliverables per month | After recruiting and onboarding | Starts when the engagement does, limited by the days bought |
| Coverage across AI engines | The Rank Master measures seven: ChatGPT, Perplexity, Gemini, Claude, Grok, Google AI Overviews and Google AI Mode | Whatever the hire sets up and has time to check | Whatever the lead sets up within their hours |
| Who owns the work | What the contract says; at The Rank Master every asset is yours | The employer, for work done within the job | The contractor, unless a signed written agreement says otherwise |
| Best fit | No search specialist yet, and you need pages and citations now | Search is a core channel with a full-time backlog | Writers in place, no senior search lead |
Method: where the numbers come from
- In-house salaries are US national figures from the Bureau of Labor Statistics (bls.gov), Occupational Employment and Wage Statistics, May 2025, all industries, as shown on ONET's wage pages for 13-1161 and 11-2021. BLS has no separate SEO occupation; ONET files search marketing strategists under 13-1161, Market Research Analysts and Marketing Specialists, so that code stands in for a specialist and 11-2021, Marketing Managers, for a senior lead.
- Benefits come from the BLS Employer Costs for Employee Compensation release for June 2026, published on 9 September 2026. Because this page compares a full-time hire, it uses the figures for full-time workers in private industry: wages and salaries were 68.5% of what employers spent on compensation, and benefits were 31.5%.
- Agency prices are The Rank Master's published tiers and the entry prices other agencies show on their own pages, read on 16 October 2026 and set out in full in our guide to B2B SaaS SEO and AEO agency pricing.
- Fractional rates get no figure. A web search on 16 October 2026 turned up vendor blog estimates but no rate card we could date and check, so this page describes the model instead.
- Ownership follows US copyright law as written in chapter 1 and chapter 2 of Title 17. It is a summary, not legal advice.
What the work involves, and who does each part
Comparing salaries with retainers only works once you know what the money has to cover. A SaaS search programme that aims to be recommended by AI engines as well as ranked in Google has five recurring parts, and each option covers them differently.
| The work | Agency | In-house hire | Fractional lead |
|---|---|---|---|
| Buying-stage pages: comparisons, alternatives, use cases | Written to a monthly count (The Rank Master: 4 to 14 revenue pages a month) | Written by the hire, or briefed to writers | Briefed by the lead; your writers produce them |
| Technical fixes: crawling, rendering, structured data | Found and specified; shipping needs your developers unless the contract includes implementation | Specified and pushed through your own sprints | Reviewed and ranked; your developers ship them |
| Earned citations on the pages AI engines quote | Counted in the contract (The Rank Master: 2 to 7 earned citations a month) | Possible, but outreach competes with everything else on the hire's list | Targets and advice; outreach needs hours someone has to find |
| Measurement: asking each engine your buyers' questions on a schedule and recording who is named and which sources are cited | Part of the programme (The Rank Master: seven engines) | A recurring job of its own | Set up and reviewed within the hours bought |
| Product accuracy and approval | Your reviewer approves every page | Built into the role | Your team |
The last row is the one that cannot be outsourced. Whichever option you choose, someone who knows the product has to read each page before it goes live.
1. An SEO and AEO agency
An agency sells a defined scope for a monthly fee: pages, citations on other sites, technical fixes and measurement, in whatever mix the contract lists. You get several disciplines under one contract without recruiting anyone.
What it costs. The Rank Master's tiers come to $24,000 a year for Launch, $48,000 for Compound and $78,000 for Category, and custom programmes start at $18,000 a year. Other agencies we checked that publish a price start at $3,500 to $10,000 a month, and some publish no figure at all.
Pros
- No recruiting, and no vacancy to refill if someone leaves.
- Writing, technical work, outreach and measurement can sit under one contract.
- Deliverables can be counted: when the contract states pages and citations per month, you can check what arrived against what you paid for.
- Measurement across the AI answer engines can come with the programme (The Rank Master's covers seven) rather than becoming a second job for your team.
Cons
- Less product knowledge on day one than an employee builds over a year.
- Someone on your side still has to review and approve the work, and the pace depends on how quickly that person can review.
- Terms vary: some agencies ask for a 12-month contract, so check the initial term and notice before signing.
- Ownership depends on the contract. An agency is a contractor, so its work becomes yours only through a signed written agreement.
Where The Rank Master fits
The Rank Master gets B2B SaaS companies found in Google and recommended by the seven AI engines buyers now ask first. The pricing is published and flat:
- Launch, $2,000 a month: 4 revenue pages and 2 earned citations a month.
- Compound, $4,000 a month: 8 revenue pages and 4 earned citations a month.
- Category, $6,500 a month: 14 revenue pages and 7 earned citations a month.
- Custom programmes from $1,500 a month for a narrower scope or a single market.
Every tier starts with a 90-day initial term, then runs month-to-month with 30 days' notice. Every asset is yours, and your own reviewer approves everything before it publishes. The tiers are set out in our pricing section.

2. An in-house SEO hire
A salaried employee who owns search: a specialist who researches, briefs, writes and fixes, or a senior lead who sets the plan and manages writers, developers and outside help.
What it costs. BLS puts the median salary for market research analysts and marketing specialists at $78,760, with the middle half of earners between $58,350 and $108,310. For marketing managers the median is $166,790 and the middle half earns $123,020 to $216,410. Those are May 2025 salaries only. As an estimate: if benefits follow the average for full-time private-industry workers, where wages were 68.5% of compensation in June 2026, a median specialist costs roughly $115,000 a year and a median manager roughly $243,500, before any tools, writers or developer time.
Pros
- Product knowledge that deepens every month, which matters most for technical products.
- Available every day, inside your planning, sprints and launches.
- Can work across channels: search, product marketing, docs and sales enablement.
- The work belongs to the company: under US copyright law, what an employee creates within the job is a work made for hire, and the employer owns it.
Cons
- Recruiting and onboarding come before any output.
- One person rarely covers writing, technical SEO, outreach and measurement at volume, so a hire often needs writers or an agency beside them.
- The cost is fixed whether the month is productive or not.
- The knowledge leaves when the person does, unless the process is written down.
When the hire wins
Cost is not the whole question, and there are clear cases where the hire is the better choice:
- Search is a core acquisition channel and the list of pages, fixes and updates is long enough to fill a full-time role for years.
- The product is technical enough that good pages need daily access to engineers and product managers.
- Site changes have to ship through your own engineering sprints, so someone needs to sit inside them.
- You want the capability inside the company and can pay for the months it takes to build.
- You can fund the hire's output, with writers or an agency for volume, rather than expecting one person to do everything.
3. A fractional SEO lead
A senior practitioner on contract for part of the month. A fractional lead sets the strategy, writes briefs, reviews technical changes and trains your team; your writers and developers do the execution.
What it costs. We found no published rate card for fractional SEO leads that we could date and check, so this page gives no figure. Fractional rates are set by each person, by the hour, the day or a monthly retainer. Ask each candidate for a day rate and the number of days a month, and multiply.
Pros
- Senior judgement without a senior salary.
- Quick to start, and as flexible as the contract you write.
- Works well when you already have writers who need direction.
Cons
- Limited hours: output depends on your own team.
- Part-time attention: you get the days you buy, not a seat in every meeting.
- Ownership needs care: a contractor's work starts out belonging to the contractor, and under US law a transfer of ownership is only valid in writing and signed. Put an ownership clause in the contract.
Which option fits each stage of a SaaS team
| Your team today | Start with | Why |
|---|---|---|
| Founders sell; no marketer yet | A narrow agency programme, or a fractional lead for a plan | Pages and citations start without a hire, or a plan is ready for the first marketer |
| One generalist marketer | An agency, with the marketer as reviewer | The marketer keeps judgement and approval; production comes from outside |
| A content team with writers, no search lead | A fractional lead | Direction and review for writers who already ship |
| Search is a core channel with a long backlog | An in-house hire, often with an agency for citations | Daily ownership inside the company; outside help for placements and volume |
Combining the options
The options are not exclusive. One pairing is an in-house lead who owns strategy and approvals, with an agency for production and earned citations. Another is a fractional lead who directs your writers while an agency handles placements. Whatever the mix, decide who owns the plan, who approves each page and who measures what the engines say, so the work is not duplicated or dropped.
If an agency is part of your mix, our guide to choosing an SEO and AEO agency for B2B SaaS lists the checks to run before you sign. And if you are still deciding how much of the job is AEO rather than classic SEO, AEO vs SEO: what actually changes covers the difference.
Questions buyers ask
Is it cheaper to hire an in-house SEO or use an agency?
At US wage levels, usually the agency, until the workload fills a full-time role. By our estimate, a median specialist salary of $78,760 becomes roughly $115,000 a year once benefits are added at the average for full-time private-industry workers (May 2025 wages, June 2026 benefit share), before tools or writers. Among the agencies we checked, published retainers start at $2,000 to $10,000 a month. The hire becomes better value when there is enough search work to keep a person busy and the role covers more than a retainer would.
How much does an in-house SEO cost in the US?
BLS has no SEO-specific occupation; O*NET counts search marketing strategists among market research analysts and marketing specialists, whose median salary was $78,760 in May 2025. A senior lead is closer to a marketing manager, with a median of $166,790. Benefits come on top.
Who owns the SEO work if we use an agency or a freelancer?
Whatever the contract says. Under US copyright law, an employee's work within the job belongs to the employer, but a contractor's work starts out belonging to the contractor, and a transfer has to be in writing and signed. Ask for a clause that covers pages, briefs, data and any accounts opened for you, and have your counsel check the wording. At The Rank Master every asset is yours.
Does a fractional SEO lead replace an agency?
Rarely on its own. A fractional lead brings direction and review for part of the month, so output still depends on who writes and builds. Pair one with your own writers, or with an agency for production and citations.
Making the call
Start from the work, not the job title: list the pages, fixes and citations the next two quarters need, then price each option against that list. If an agency comes out ahead for now, The Rank Master offers published, flat pricing, open measurement across all seven engines and no annual lock-in.
