Paid search is a different animal than organic
Before you decide who runs it, understand what you are deciding about. Google Ads is not SEO. The whole DIY-versus-agency question changes because the mechanics are different, and owners who carry over their instincts from organic get burned.
Organic ranking is slow and forgiving. You publish a page, it takes months to move, and a mistake mostly costs you time. Paid search is fast and unforgiving. You turn it on and clicks start costing money the same afternoon. A mistake on Ads does not cost you a ranking you never had. It costs you the actual budget, spent on the wrong searches, before you notice. That is the core reason the DIY math here is not the same as DIY SEO.
The three things that make paid its own animal, and that decide whether you should run it yourself:
- It bills continuously. There is no set-and-forget. An account left alone drifts: Google widens your matches, spends on searches you never chose, and the waste compounds daily. DIY Ads is a weekly habit or it is a leak.
- The auction moves. Your competitors change bids, your cost-per-click swings with the season, and a heat wave or a storm can spike your trade's clicks overnight. You are managing a live market, not a static page.
- Small mistakes cost real money fast. One missing negative keyword, one campaign pointed at your homepage, one broad-match term left off leash, and you can burn a month's budget on clicks that never book a job.
None of that means DIY is wrong. It means the question is not "can I learn Google Ads" (you can) but "can I watch this live account every week and catch the leaks before they cost me." That is a real commitment, and it is the honest thing to weigh, not the sticker price of a management fee.
What running Google Ads yourself really takes
The Google Ads interface will let anyone create a campaign in twenty minutes. That is the trap. Building a campaign is easy. Building one that books jobs instead of burning budget is the actual work, and it is ongoing. Here is what DIY honestly asks of you.
The setup, once. Structured campaigns and ad groups by service, ad copy that matches the search, a real negative-keyword list from day one, conversion tracking wired up (calls and forms), your service area and hours locked, and a dedicated landing page the ads point to instead of your homepage. Miss the tracking or the negatives and you are flying blind while paying full fare.
The upkeep, forever. This is the part owners underestimate. Every week or two: read the search-terms report and add new negatives for junk searches you paid for, adjust bids on what books and pause what does not, dispute wrong-number and out-of-area leads on Local Services Ads before the credit window closes, and check that your cost-per-lead is not creeping. That is a couple of focused hours every week, indefinitely, in the account, not a one-time build.
The skill that is not obvious. Reading the account for cost-per-booked-job, not clicks. Knowing that broad match without tight negatives is a faucet left running. Knowing that position one is not always the cheapest booked job. Knowing which of your leads Google should credit back. None of it is genius, but all of it is learned on live money, and the tuition is your budget while you learn.
Be honest about the upkeep line specifically. Most owners can build a campaign on a slow Sunday. Almost none can reliably read the search-terms report every single week through their busy season. And an untended paid account does not coast. It leaks. That gap, between the easy setup and the relentless upkeep, is where most DIY Ads efforts quietly bleed money.
What an agency actually buys you
An agency is not selling you a Google secret. There isn't one. What a paid-search shop that has run local-service accounts since 2008 actually sells is three things that are hard to buy yourself: the setup done right, the weekly tending, and the read on your numbers that turns clicks into booked jobs.
Setup that does not leak. Negatives in from day one, campaigns structured by service, conversion tracking that actually fires, service area and dayparting locked, and ads pointed at a real landing page. Getting this right at the start is most of the game, because a leak baked into the setup spends your money every single day until someone catches it.
The tending you will not do in July. The search-terms report read every week, negatives added, bids tuned, junk LSA leads disputed inside the credit window, budget shifted to what books. This is the part that decides whether Ads works, and it is exactly the part an owner drops when the phone rings. A shop does it because it is their job, not a side task.
The math you cannot see from inside the account. A good shop reads for cost-per-booked-job against your ticket size, not vanity clicks. They know your trade's CPC, a realistic conversion rate, and where your budget is leaking. Since 2008 the trade behind this brand has run these accounts, so we speak dispatch, service area, and ticket size, not impressions.
What an agency does not buy you: a reason to check out, or lower clicks by magic. Competitive CPCs are competitive for everyone. What management earns is more booked jobs per dollar, mostly by cutting waste and lifting conversion, not by beating Google's auction. And a shop worth hiring will tell you plainly when your budget is too small to bother managing, instead of taking a fee to run pocket change.
The math nobody puts on the table: the management fee
Here is the number that actually decides DIY versus agency, and the one padded quotes hide. When you hire a shop to run paid search, you pay two separate things: your ad budget (money that goes to Google as clicks or leads) and a management fee (money that goes to the agency to run the account). DIY skips only the second one. Do that math before anything else.
Management is usually charged one of two ways: a percentage of ad spend (commonly 10 to 20 percent) or a flat monthly. On a small budget, that fee can swallow the whole point of running Ads. On a large one, it is a rounding error against the waste it prevents. That is the crux.
| Monthly ad budget | Rough management fee | Does hiring pay off? |
|---|---|---|
| $500 to $1,000 | $300 to $500 flat, or 15% | Usually not. The fee is too big a share of a small budget. This is where DIY makes the most sense. |
| $1,500 to $3,000 | $400 to $600, or 15% | It depends. If the account is leaky, management can pay for itself out of the waste it removes. |
| $3,000 to $8,000 | $500 to $1,200, or 12 to 15% | Usually yes. At this spend, a few points of wasted budget dwarf the fee, and tending matters more. |
| $8,000 and up | 10 to 15% | Almost always. The stakes and the leaks are large enough that skilled management is cheap insurance. |
Run your own numbers against that. If a tighter account (negatives added, service area locked, ads on a real landing page) recovers 20 to 40 percent of a leaky budget (the common range), then on a $4,000 budget you are recovering $800 to $1,600 a month. A $600 management fee that recovers that is not a cost, it is a trade you win. On a $700 budget, the same fee eats the account. Same service, opposite verdict, and the budget line is what flips it.
The honest read: if your budget is small and your trade is cheap, DIY the account and keep the fee in your pocket. If your budget is real and your clicks are expensive, the fee is almost always smaller than the waste it removes. Anyone who quotes you a fee without asking your budget or your ticket size is guessing, and you should treat the quote that way.
DIY vs agency, by trade and market
There is no universal answer, because a landscaper and a restoration shop live in completely different paid-search worlds. The right call tracks three things: how expensive your clicks are, how big your budget is, and how much a mistake costs you. Find your own row.
| Your situation | Leans DIY | Leans agency |
|---|---|---|
| CPC in your trade | Low ($4 to $12: lawn, pressure washing, garage door) | High ($15 to $75: plumbing, HVAC, roofing, restoration) |
| Monthly ad budget | Under about $1,500 | $3,000 and up |
| Cost of a mistake | Small (cheap clicks, low ticket) | Large (expensive clicks burn fast) |
| Weekly time you can commit | You will read the report every week | You will not, honestly, in season |
| Setup complexity | One service, one area | Multi-service, multi-market, LSA plus Search |
Read it by your reality, not the averages. A pressure-washing shop with a $700 budget and $6 clicks can genuinely DIY: the clicks are cheap, the account is simple, and a bad week costs a few dozen dollars, not a few thousand. Learning on that account is affordable tuition. Turning a $600 management fee loose on a $700 budget would be absurd.
Now flip it. An HVAC company running $5,000 a month across repair and install, with clicks that hit $40 in a heat wave, cannot afford to run it loose. One untended week of broad match in peak season can torch a serious chunk of that budget on searches that never booked. Here the mistake is expensive enough that skilled tending is cheap by comparison, and the owner has the least free time exactly when the account needs the most attention.
The middle band, roughly $1,500 to $3,000, is where it comes down to one honest question: will you actually read the search-terms report every week, or won't you? If yes, DIY can work. If you know you won't once summer hits, hire it out, because a paid account you stop watching does not pause. It bleeds.
The hybrid that fits most contractors
DIY versus agency is a false binary on paid search too. For a lot of contractors the right answer is a split: hire the setup and the read, keep a light hand on the day-to-day, or the reverse. The mix depends on your budget and how much you actually want to touch it.
Hire the build, run the upkeep yourself. This works when your trade is simple and your budget is modest. A shop builds the account right once: structure, negatives, conversion tracking, a real landing page, service area and hours locked. Then you run the light weekly upkeep on a foundation that is not leaking. You skip the ongoing fee but avoid the setup mistakes that sink most DIY accounts. The catch is you still have to do the weekly tending, honestly, or the clean build drifts.
Hire the tending, stay in the loop. The more common split at real budgets. The shop runs the account and reads the numbers; you supply the trade knowledge that makes it work: which services are worth the most to you, what a real emergency call is worth, your true service radius, your close rate. You are not checked out, you are the source. They are the engine. This fixes the two ways DIY paid search fails (leaky setup and dropped upkeep) without you living in the account.
One piece almost always belongs with the shop regardless of the split: the landing page the ads point to. Paid clicks sent to your homepage waste money, because a homepage explains your whole company when a paid click needs one job, one offer, one phone number, one form. A dedicated, fast landing page is a one-time build, not a monthly bill, and it lifts conversion enough to move cost-per-lead more than any bid change. Get that built right, then decide how much of the rest you honestly want to carry.
And the piece that is always yours, no matter who runs the account: the Google Ads account itself must be in your name. You own it and your data, always. That one does not get delegated.
Before you hire (or DIY): the questions that decide it
Whether you hire a shop or run it yourself, run your situation through these questions first. They are the same checks a good shop would run, and they keep you from paying a fee you don't need or DIY-ing an account that will bleed.
- How expensive are clicks in my trade? Cheap clicks ($4 to $12) make DIY mistakes affordable. Expensive clicks ($15 to $75) make one untended week costly enough that tending pays for itself.
- How big is my budget, honestly? Under about $1,500, a management fee is usually too big a share to justify. Above $3,000, the waste a fee removes almost always exceeds the fee.
- Will I read the search-terms report every week? Not this month. Every week, including August. If the honest answer is no, DIY leaks, and a leak on paid search is real dollars, not lost rankings.
- What is a booked job worth to me? A $12,000 install covers a lot of ad spend; a $300 clean does not. Your ticket decides whether Ads pencils at all, and whether a fee on top of it does.
- Who will own the account? If you hire, the account stays in your name, always. Any shop that keeps it in theirs can leave you at zero when you go. If you DIY, you already own it. Keep it that way.
If most answers point to DIY (cheap clicks, small budget, real weekly time, simple setup), run it yourself and run it tight. If most point the other way (expensive clicks, real budget, no spare hours in season, a costly mistake), hire the tending, or at least the build. If you are genuinely split, the hybrid is your answer.
Every honest path starts the same way: knowing where you actually stand. That is why we lead with an audit, delivered in 1 to 3 business days, before anyone quotes a fee. It reads your trade CPC, your current account if you have one, and where the budget is leaking, and gives you a real cost-per-booked-job estimate. Even if you decide to DIY from there, you will do it knowing the real numbers. And if your budget is too small to bother managing, we will say so, because that is how you know the read is straight.
