What an In-House Marketing Hire Actually Costs
The job posting says "Marketing Coordinator, $50k." The real number is higher. Add payroll tax, benefits if you offer them, a laptop, Adobe or Canva, an email platform, a CRM seat, and the ad spend they'll need to actually run campaigns. A realistic all-in number for one marketing hire at a mid-size contracting business runs $65,000 to $95,000 a year once you count software stack and ad budget, not just the salary line.
That buys you one person. One person cannot be a working SEO strategist, a paid ads buyer, a content writer, a web developer, and a social media manager at the same time. Every job posting for a "Marketing Manager" at a contracting business lists all five of those skills as requirements. Nobody is genuinely strong at all five. You'll get someone who's decent at two of them and learning the other three on your dime, on a live budget, while your competitors' phones keep ringing.
Then there's ramp time. A new hire needs 60 to 90 days just to understand your service area, your crews, your busy season, and your CRM before they produce anything that moves the needle. Add another two or three months before search engines and AI answer engines start treating new content and technical changes as established signal, not noise. An agency that's done this for other trades starts week one with a process already built, and doesn't need three months of paid learning curve before the first real deliverable lands.
Software is its own line item people underbudget. A marketing hire who's supposed to cover SEO needs a keyword research tool, a rank tracker, and a technical audit tool. Add content tools, design tools, an email platform, and a CRM seat, and the software stack alone can run $300 to $800 a month before a single ad dollar gets spent. None of that shows up on the offer letter, and all of it shows up on the first-year budget.
- Salary + payroll tax + benefits: the number on the offer letter is never the real number
- Software stack: CRM, email platform, design tools, SEO tools, analytics, scheduling
- Ad spend: someone still has to manage the Google Ads or Facebook budget separately
- Ramp time: 60-90 days before they're productive, paid the whole time
- Turnover risk: when they leave, the institutional knowledge, login credentials, and half-finished campaigns leave with them
None of that means an in-house hire is a bad idea. It means the math only works when the business is big enough to spread that cost across a real team, or specific enough in scope (someone running reviews and local social, nothing else) that one person can actually own the job without pretending to be five specialists at once.
What an Agency Actually Costs and What It Covers
Agency retainers for contractor marketing generally run from a few hundred dollars a month for a narrow local SEO package up to several thousand a month for full SEO plus content plus AI-search visibility work. The range is wide because the scope is wide. A roofing company chasing storm-season traffic in three counties needs more than a single-location plumber renewing the same 20 residential customers a year, and pricing should reflect that instead of a flat rate applied to every trade.
What you're actually buying with a retainer is a team, not a person. A competent agency has someone who lives in Google Search Console, someone who writes trade-specific content, someone who understands how AI answer engines pull citations, and someone who builds and maintains the site itself. You get that whole bench for less than one full-time salary, because the agency spreads those specialists across many client accounts and isn't paying one person to context-switch between five disciplines in a single afternoon.
Timelines matter here too. SEO and AI-search visibility are not paid-ad campaigns you can turn on and see results from in a week. Competitive terms typically take four to nine months to show meaningful ranking movement, regardless of whether the work is done in-house or by an agency. A contractor who fires an agency after 60 days because "nothing happened yet" usually hasn't given either model enough runway to prove out, and would have hit the same wall with an in-house hire on the same timeline.
| What you get | In-house hire | Agency |
|---|---|---|
| SEO strategy + execution | If they have time and skill | Core service |
| Content writing at volume | Rare, slow | Built into scope |
| AI search / AIO visibility | Almost never in-house today | Emerging core service at specialized shops |
| Site build + maintenance | Needs a second hire or contractor | Included or add-on |
| Coverage when someone's out | Nobody covers for one person | Team continues without interruption |
The tradeoff runs the other way too. An agency doesn't answer the phone at your shop, doesn't know your crew by name, and isn't in the truck. If you want someone who lives inside your day-to-day operation, badges reviews personally, and handles customer-facing social in real time, that's a different job than what most agencies are built to do, and it's worth being honest about that gap before signing a contract that doesn't cover it.
The Hybrid Model: What It Actually Looks Like
Most contracting businesses that get this right don't pick one side cleanly. They keep one person in-house who owns the relationship, the phone, the reviews, and the day-to-day social posts, and they hire an agency for the technical lift: SEO strategy, content production at volume, AI search visibility, and the website itself.
This works because the split matches actual skill sets. Reviews and local social are relationship work, best done by someone who knows the crew and the customers. SEO and AI-search visibility are technical and cumulative work that rewards specialization and consistency over years, not hours squeezed between other duties.
The failure mode is the reverse split: hiring one generalist in-house and expecting them to also handle the technical SEO and content work an agency specializes in. That's how a marketing hire ends up spending three days trying to fix a schema markup issue that a specialist would resolve in twenty minutes, while the reviews and social feed both go stale.
- In-house strength: reviews, local relationships, day-to-day social, answering the phone
- Agency strength: SEO strategy, content volume, technical site work, AI search visibility
- Rare but real: a business large enough to run both in-house at full strength, no agency needed
If you're going to build a hybrid, define the split on paper before you hire or sign anything. Vague ownership between an in-house hire and an agency is where marketing budgets quietly disappear, with each side assuming the other covers a gap that nobody actually covers.
When an In-House Hire Is the Right Call
There are real scenarios where hiring in-house beats an agency, and it's worth naming them honestly instead of pretending the answer is always "hire an agency."
If your business does $8M or more in annual revenue and can support a real marketing department (three or more people, not one generalist), in-house makes sense because you can hire specialists the way an agency does: one for content, one for paid ads, one for reviews and reputation, one for the technical SEO and site work. At that scale, the cost of building the team in-house competes directly with agency retainer pricing, and you get someone in the building who knows your crews, your seasonal patterns, and your close rate by lead source without a monthly handoff call.
If your business already has strong organic reputation and referral flow and mainly needs someone to keep reviews coming in, post job-site photos, and follow up on leads that are already showing up, a part-time or full-time coordinator can handle that without needing deep SEO or AI-search expertise. That's a narrower job description than most "Marketing Manager" postings admit to, and it's one person can genuinely do well, especially paired with an agency handling the parts that require technical depth.
Multi-location contractors are a special case worth naming separately. A business running four or five branches across a metro area often benefits from one in-house marketing liaison who coordinates between branch managers, standardizes review requests, and keeps local listings and photos current at every location, while an agency runs the SEO and content strategy that applies across all locations at once. Neither side alone covers that well: an agency doesn't have the daily visibility into five separate crews, and one branch-level employee doing SEO for five locations from scratch is starting from zero five times over.
If you've already tried an agency and it didn't perform, in-house isn't automatically the fix. Before concluding the model is wrong, check whether the agency was actually working the fundamentals: content volume, technical SEO, citations, and now AI-search visibility. A lot of "the agency didn't work" stories trace back to a retainer that only covered social posting with no SEO behind it, or a timeline that never reached the four-to-nine-month mark competitive terms typically need before ranking movement shows up.
- $8M+ revenue, can staff a real 3+ person department
- Strong existing reputation, mainly needs review/social/follow-up coverage
- Multiple locations where a dedicated local liaison earns their keep, alongside an agency running the SEO layer
Outside those cases, the math tends to favor an agency, or the hybrid model above.
Red Flags on Both Sides
On the in-house side, the biggest red flag is a candidate whose entire background is social media management dressed up as "digital marketing." Posting job-site photos and running a Facebook page is real work, but it's not SEO, and it's not the same skill set that gets a plumbing company found when someone in their service area searches "emergency plumber near me" or asks an AI assistant for a recommendation. Ask directly what they've done with technical SEO, not just content calendars.
Another in-house red flag: no clear reporting cadence. If a candidate can't describe how they'd show you results monthly, in plain numbers, that's a preview of what the job will look like six months in, when you're asking "what have you actually been doing" and getting a vague answer about brand awareness.
On the agency side, the biggest red flag is a contract with no defined deliverables. "We do SEO" is not a scope of work. A real retainer specifies content volume, technical audit cadence, link or citation building activity, and reporting format, in writing, before money changes hands. If an agency won't commit specifics to a contract, that's usually because there aren't specifics to commit.
A second agency red flag: locked-in ownership. If the agency owns your domain, your site code, or your content in a way that makes leaving expensive or technically difficult, that's a structural problem regardless of how good the actual marketing work is. A contractor should always be able to walk away with their domain, their site, and their content intact.
- In-house: social-only background dressed up as full marketing expertise
- In-house: no clear plan for measuring or reporting results
- Agency: vague scope of work with no defined monthly deliverables
- Agency: contract terms that make leaving with your own site and domain difficult
- Either: no mention of AI-search visibility as search behavior shifts toward AI answer engines
Vetting either path the same way you'd vet a sub you're hiring for a job: check the specifics, check the track record, and don't sign anything that isn't in writing.
Questions to Ask Before You Decide
Whichever way you lean, run these questions before committing a year of budget to either path.
For an in-house candidate: ask them to walk through how they'd approach your specific trade and service area in the first 90 days. If the answer is generic ("post more, engage more"), that's a marketer who hasn't done technical SEO work before. Ask what tools they've used for keyword research, technical audits, and citation management. If they can't name any, they're a social-media hire wearing a marketing title.
For an agency: ask for the specific deliverables in a typical month, not just "we do SEO." Ask how many pages of content get produced, whether technical SEO audits happen on a schedule or only when something breaks, and whether AI-search visibility (how a business shows up in ChatGPT, Perplexity, and AI Overviews) is part of the scope or a separate line item. Ask what happens if you want to leave: do you keep the content, the site, and the domain, or does everything belong to the agency.
For either path: ask what gets reported monthly and in what format. A marketing spend you can't see the results of is a marketing spend you can't manage. You should be able to see traffic, ranking movement on target terms, lead volume, and lead source, every month, without asking twice.
- What's the 90-day plan, specifically, for my trade and area
- What tools or process do they use for technical SEO, not just content
- Is AI search visibility part of the scope or an unaddressed gap
- Who owns the site and content if the relationship ends
- What does the monthly report actually show
A contractor who asks these five questions up front avoids most of the bad hires and bad retainers that make people conclude "marketing doesn't work for my trade." It usually wasn't the model. It was the vetting.
