You closed your Series A. The board wants a growth plan that aligns with the SEO business goals. SEO is on the list, but you're the only marketer, and the question hits immediately: do you hire someone to own SEO in-house, or outsource it to an SEO provider?
Startups routinely waste months and tens of thousands of dollars by outsourcing SEO before they understand what good SEO looks like for their business.
This article gives you a different framework for understanding in-house vs outsourced SEO. Instead of listing generic pros and cons, it walks through the decision in sequence: what to do first, when to bring in outside help, and how to avoid the most common mistakes. The advice comes from CMOs who built marketing functions at companies like Box, Elastic, Divvy, and several Series A startups.
Why most "SEO in-house vs. outsourcing" advice fails at Series A
The standard comparison assumes you already have a marketing team, a content engine, and an established brand. At Series A, you have none of those. You're not choosing between two functional options. You're choosing how to start from zero.
This distinction matters because the tradeoffs are different. An established company weighing seo in house vs. outsourcing is optimizing an existing function. A Series A CMO is building one. The risks are different, the costs are different, and the decision criteria are different.
Sterling Snow, former CMO at Divvy (acquired by Bill.com for $2.5B), describes the early stage as "the haystack phase" where proven playbooks break down:
"People who say that they're data driven in the haystack phase, like there's no data. So like, what are you talking about?"
The SEO playbook that worked at your last company (topic clusters, pillar content, backlink campaigns) assumes existing domain authority and content resources. A Series A company has neither. The real question is not "which is better?" but "what do I do first, and in what order?"
That order starts with something counterintuitive: doing it yourself.
The "do it yourself first" principle
You cannot outsource what you have not done yourself. This is the single most important principle for Series A CMOs evaluating building an in-house SEO team vs. outsourcing, and no ranking article mentions it.
The logic is simple. If you hand SEO to an agency before you've personally done keyword research, written a few articles, and reviewed your site's technical health, you have no way to evaluate whether the agency is doing good work. You can't tell the difference between a strategic recommendation and a generic playbook.
Kat Wendelstadt, CMO at Electric Twin and a three-time marketing leader, describes this approach on the FINITE B2B Podcast:
"I like to take things to the absolute limit - to the point where I can no longer handle it - so I know where the gap is and who I need to hire first."
Stijn Hendrikse, CEO of Kalungi, reinforces this from the agency side when discussing in-house SEO vs outsourcing.
"The moment you give your work to someone else to do, you need to know how to assess whether an in-house SEO team is doing a good job. And it is really hard to do that unless you've done the job yourself."
"Doing it yourself" does not mean becoming an SEO expert. It means spending 4-8 weeks on the fundamentals:
- Run keyword research for your core product categories in your SEO campaign. Identify 20-30 terms your buyers actually search.
- Write 5-10 articles targeting those terms. They don't need to be perfect. The point is to learn what your audience responds to in relation to your business goals.
- Complete a basic technical audit. Check your site's indexing, page speed, and crawl errors using free tools like Google Search Console and Screaming Frog.
- Review what competitors rank for. Identify the articles already ranking for your target terms and note what they cover and what they miss in relation to current SEO trends.
After this phase, you'll know three things: which parts of SEO you're decent at, which parts you hate, and which parts require expertise from an experienced SEO you don't have. That's the information you need to make a smart outsourcing decision.
The cost of skipping this step is real. Hendrikse warns about the "start-stop" pattern that burns both time and money in search engine optimization efforts.
"If you go through the effort, which takes multiple weeks typically, to onboard an agency, to then get impatient with the results and stop it three weeks later, four weeks later, now you've not only wasted a lot of time, you've probably wasted a lot of money too."
Once you've built that baseline understanding, you're ready to evaluate the actual options.
SEO in-house vs. outsourcing: the real pros and cons for startups
Both options carry real risks at Series A, and the risks are different from what established companies face. Here's what each path looks like when you don't have an existing in-house team or content library for your SEO efforts.
In-house SEO at a Series A startup
The biggest advantage of an in-house SEO hire is product knowledge specific to our marketing strategy, which is crucial for effective SEO. SEO for a technical product requires someone who understands the buyer's language, and an internal person picks that up faster than any agency.
The biggest risk is the dependency problem. An in-house SEO professional expects content writers, designers, and developer support from the in-house team to implement their specific SEO recommendations. At a Series A startup, those resources don't exist.
Jen Grant, a three-time CMO who led marketing at Box, Elastic, and Looker, saw this pattern repeatedly at early-stage companies. Speaking on the Never Too Early Podcast, she described the failure mode in the context of in-house SEO vs outsourcing.
"I think where I haven't hired well is where I've looked for a demand gen person and not realized the stage that I'm at and the chaos that we have. And then you get a person in that expects a bit more support from the rest of the company... they're like, 'Oh, but I need content.' And at a startup, you're like, 'Uh, who's going to do that?'"
The fix is to hire generalists, not specialists. Grant calls it the "GSD" (Get Shit Done) mindset: people who will "pick up a box and carry it if the box needs to be carried." A pure SEO specialist who needs a content team, a design team, and a dev team to execute is the wrong hire at this stage.
Outsourcing SEO at a Series A startup
The biggest advantage of an agency is immediate access to a full team: strategists, writers, link builders, and technical SEO analysts. You skip the 3-month recruiting process and get execution capacity on day one.
The biggest risk is what Hendrikse calls "agency fatigue." Each agency demands onboarding workshops, stakeholder interviews, weekly status calls, and constant feedback loops. For a CMO who is also running demand gen, managing the sales handoff, and building the brand, this management overhead adds up fast.
"I sometimes describe this as agency fatigue, where especially when you're a small startup, you just don't have the bandwidth or time to manage all those different agencies."
The second risk is generic output. SEO agencies that don't specialize in your stage or industry default to the same playbook they use for every client in search engine optimization. The content reads like it was written for "companies" in general, not tailored for your specific buyer, which is a common pitfall in SEO outsourcing. Your blog fills up with articles that rank for nothing and convert nobody, highlighting the risks of poor SEO outsourcing.
These tradeoffs raise an obvious question: what does each option actually cost?
SEO in-house vs. outsourcing cost comparison for Series A startups
A single in-house SEO hire costs $100K-185K per year when you include overhead. An agency runs $36K-96K per year. But the sticker price hides several costs that matter more at the startup stage.
In-house cost model
A realistic budget for one in-house SEO person at a Series A startup:
- Junior SEO specialist: $60-80K salary + ~30% for benefits and overhead = $78-104K/year
- Senior SEO manager: $90-130K salary + overhead = $117-169K/year
- SEO tools (Ahrefs, Semrush, Screaming Frog): $5-15K/year
- Freelance content production (writers, designers): variable, but plan for $2-5K/month
Total: $100-185K/year for a single person, not including the content production budget.
Agency cost model
- Startup-focused agencies: $3,000-8,000/month ($36-96K/year)
- Enterprise agencies: $10,000-25,000/month (overkill at Series A)
- Freelancer or fractional SEO leader: $2,000-6,000/month ($24-72K/year) for SEO services.
The hidden costs that change the math
The line items above miss three costs that disproportionately affect startups:
- Management time. Plan for 5-10 hours per week of CMO time managing either an in-house hire or an outsourcing to an agency relationship. At Series A, your time is the most expensive resource you have.
- Bad hire risk. A wrong in-house hire costs 3-6 months of lost momentum plus severance and rehiring costs. According to the U.S. Department of Labor, a bad hire can cost up to 30% of the employee's first-year earnings.
- The start-stop tax. Switching between SEO agencies and in-house hiring loses 2-3 months of momentum each time. At Series A, where the window to Series B is 12-18 months, that's a significant percentage of your runway.
These hidden costs point to why a growing number of startup CMOs skip both the full-time hire and the traditional agency, at least initially.

Book a CallThe third option: fractional and freelance SEO
A fractional SEO leader, someone who works 10-20 hours per week on strategy and vendor management, is often the best first move for Series A companies. No top-ranking article for "SEO in-house vs. outsourcing" covers this as a distinct option.
A fractional SEO leader is not an agency and not a full-time hire. They own your SEO strategy, manage any freelancers or agencies you bring in later, and build the systems that a full-time hire will eventually take over. They cost $3-6K per month, roughly one-third the total cost of a full-time senior hire and comparable to a mid-range agency retainer. If you're considering this route, our guide on how to hire an SEO consultant covers what to look for.
Wendelstadt uses this model deliberately:
"My first hire is actually a freelancer - I like to hire freelancers first, then see if they're good and make them permanent."
This approach solves two problems at once. First, it gives you expert-level strategy without the $150K+ commitment of a senior full-time hire. Second, it functions as an extended trial. If the fractional person is excellent, you convert them to full-time. If they're not, you part ways without a painful termination process.
The fractional model works best when you've already completed the "do it yourself first" phase. You understand the basics, you know where you need help, and you can have an informed conversation about strategy with your fractional hire. Without that baseline, you're back to the original problem: you can't evaluate whether someone is doing good work in terms of effective SEO practices.
When hiring an SEO agency is not the right fit: if you need high-volume content production, technical migrations, or large-scale link building campaigns, a fractional person can't execute that alone. Those are the tasks to outsource to a specialized agency, ideally with your fractional leader managing the relationship. Before signing with any agency, review these key questions to ask when hiring an SEO company to avoid common pitfalls.
That brings up the question of how to work with an agency without repeating the mistakes that burn most startups.
The right sequence for Series A SEO
The in-house SEO vs outsourcing question is the wrong starting point for determining what is right for your business. The right question is: what do I do first, what do I do next, and when do I bring in help? If you're still unsure whether external help is even necessary, start by deciding whether you need an SEO company in the first place.
Here's the sequence that startup CMOs describe working through when deciding between in-house SEO vs hiring an SEO agency:
- Do it yourself first (weeks 1-8). Run keyword research, write initial content, audit your site. Build the baseline knowledge you need to evaluate any outside help.
- Bring in a fractional SEO professional (months 2-4). Someone who owns strategy, builds systems, and manages any specialized vendors. Cost: $3-6K/month.
- Outsource execution selectively (months 3-6). Hand off link building, technical fixes, or content production to an agency or freelancers, with your fractional leader managing quality.
- Evaluate a full-time hire (month 6+). If SEO is driving meaningful pipeline (>15-20% of qualified leads), the channel justifies a dedicated in-house person. Your fractional leader may be that person.
This sequence is not the only path. Some startups skip straight to an agency and get good results, especially if the CMO has deep SEO experience from a previous role. Others hire a generalist marketer who handles SEO alongside demand gen and content.
The common thread across every CMO we spoke with: the worst outcomes happen when companies outsource SEO before they understand it, hire specialists before they have the infrastructure to support them, or commit to 12-month retainers before testing the relationship.
Start with what you can learn about your marketing strategy. Then invest in what you can't do alone. For SaaS companies navigating this decision, working with a SaaS SEO consultant who understands the unique dynamics of your growth stage can make all the difference.
