Google Ads for plumbers: flat fee or % of spend?

Why does the pricing model matter for a plumber?

Because it shapes what your ad manager is rewarded for. Plumbing ads are expensive. Searches like "emergency plumber" or "water heater replacement" attract many bidders, and each click can cost real money. A manager who earns more when you spend more has a quiet reason to recommend higher budgets.

That does not make percentage-based managers dishonest. Many are excellent. But it is worth knowing which way the incentive points before you sign.

How does a percentage of spend work?

The manager charges a share of whatever you spend with Google each month, often with a minimum fee. Spend more, pay more in fees.

What is good about it:

• Simple to understand.
• The fee scales with account size, which can feel fair for small budgets.

What to watch:

• Raising the budget raises the fee automatically, even if calls stay flat.
• There is little reward for cutting waste, since lower spend means a lower fee.
• Reports can lean toward spend and clicks instead of booked jobs.

How does a flat fee work?

The manager charges the same fee every month for an agreed scope. Your ad spend is paid directly to Google and does not change the fee.

What is good about it:

• No reason to push spend up.
• Cutting waste, pausing bad campaigns and blocking junk searches costs the manager nothing.
• Easy to budget.

What to watch:

• The scope needs to be clear. A flat fee should come with a list of what gets done each month.
• If your account grows a lot, the fee may need to be revisited.

What should a Google Ads manager actually do for a plumber?

Whatever the pricing model, the work should look roughly the same:

1. Set up tracking first. Calls from ads, calls from the website, form fills and bookings, tracked before money is spent. Without this, every decision is a guess.
2. Split campaigns by service. Emergency repair, drain cleaning, water heaters and repiping attract different searches and deserve different ads and budgets.
3. Match your service area. Target the zip codes and cities you actually serve, and exclude the ones you do not.
4. Block junk searches. Plumbing ads attract searches for jobs, DIY tips, parts and plumbing school. Negative keywords stop paying for those clicks.
5. Match ad hours to answer hours. An emergency ad at 2am only works if someone picks up.
6. Send clicks to the right page. An emergency ad should land on an emergency page with the phone number up top, not your home page. See plumber websites that book emergency calls.
7. Report on calls and booked jobs. Not just impressions and clicks.

If your manager is not doing most of this, the pricing model is the smaller problem.

Who should own the ad account?

You should, always. The account holds your history, your conversion data and what has been learned about your market. If the account belongs to the agency and you leave, you may start from zero.

Before you sign with anyone, ask: "Is this my account, and will I keep full access if we stop working together?" The answer should be yes.

How does French Press Labs charge for Google Ads?

We charge a flat management fee, never a percentage of spend. Our ads management starts from $2,500 a month, plus ad spend paid directly to Google. You own the ad account and you see what we see. We set up tracking that fires before we spend, pace the budget through the month, block wasted searches, and pause campaigns when they stop paying off. See Google Ads for the full list.

We also look at your budget honestly. If it is too small to learn anything useful in your market, we tell you before you spend it.

Should a plumber also look at Local Services Ads?

Probably. Local Services Ads sit above regular Google Ads for many plumbing searches and charge per lead rather than per click. Many plumbers run both. They fit different jobs, and we compare them in Local Services Ads vs Google Ads.

What questions should you ask before signing?

Ask any Google Ads manager:

1. How do you charge, and does my fee change if my spend changes?
2. Who owns the account?
3. What do you track, and how do you know an ad led to a booked job?
4. What will you do in the first 30 days?
5. How do you decide when to raise or cut budget?
6. What is in the monthly report?

Clear answers to these tell you more than any pricing page.
