Porta Potty Google Ads: $13 Leads — A Real Account Breakdown

I manage Google Ads for dozens of home-service businesses. Painters, plumbers, electricians, well drillers, restoration crews. I have a client whose leads cost more than $600 apiece and I have a client whose leads cost less than a pizza.

The pizza client rents porta potties.

If you own a porta potty rental company, or a septic company, or anything in that world, I want to show you the actual account. Real numbers, straight off the dashboard, last 90 days. No projections. No "up to." By the end of this you will know exactly why these are the cheapest leads in home services, and you will be able to check the math against your own business.

Let me start with how this client found us, because it tells you something.

How this one started

They found us on YouTube. They saw we worked with companies like theirs, in that same messy, unglamorous corner of home services, and they reached out.

Here is the part I like. They were already running Google Ads with another company. They were not happy. So they gave us a shot.

That was about three years ago. Since then they have more than doubled their ad budget, and there is still room to grow. The problem they have now is a good problem. They have run into capacity. Some weeks there is more work coming in than they can take.

That is the whole game. Get a business more work than it can handle, and everything else gets easier.

They do both septic and porta potties, one company, two sides. This article is about the porta potty side, because that is where the numbers get almost silly.

The numbers, straight off the dashboard

Here is the porta potty campaign over the last 90 days.

Sit with the cost per lead for a second. Twelve dollars and ninety-three cents to make a phone ring or a form come in from someone who wants to rent a toilet.

The click-through rate is 10.8 percent. That means about 1 in 10 people who see the ad click it. In most industries you are thrilled with 3 or 4 percent. Here it is one in ten.

The conversion rate is 19.4 percent. Roughly one out of every five clicks turns into an actual lead. So you pay $2.51 for a click, you do that about five times, and one of them becomes a real customer inquiry. Five clicks at $2.51 is about $12.55. That is your lead. That is the whole trick, and the math holds up right there on the page.

Why the leads are this cheap

Two things stack on top of each other. How people buy, and how few companies bother to compete.

People rent toilets the way they order pizza. It is a commodity, the need is urgent, and nobody has a favorite porta potty brand. They search, they call whoever shows up first, they book. High intent, zero shopping around. That combination is exactly what makes a click cheap and a lead valuable.

The second thing is the auction. In advertising, when a lot of companies want to show up for the same search, they bid each other up and clicks get expensive. When almost nobody bids, clicks stay cheap.

Porta potty clicks in this account average $2.51. A plumber commonly pays anywhere from $15 to $50 for a single click, because every plumber in town is fighting for that spot. Toilets do not have that problem, because most rental operators are not running ads at all. Half of them barely have a website.

Here is the same idea across real accounts I manage, so you can see where porta potty sits:

• Porta potty rental: about $13 per lead, wide open auction
• Pressure washing: around $31 per lead
• Electrician: around $50 per lead
• Plumbing and garage door: around $90 per lead
• Well drilling: around $202 per lead
• Water and fire restoration: around $260 per lead

Same agency, same 90 days, same way of counting. The porta potty client is paying a fraction of what everyone else pays, for the same phone ringing.

Porta potty demand is really three markets

This one surprised me the first time I looked closely. It is not one market. It is three, and each behaves differently.

Construction and job sites. Contractors need units on site for the whole length of a build, month after month. It is business to business, it repeats, and one won account can rent for years. That is the highest lifetime value of the three. These buyers know what they want and rarely haggle.

Events and weddings. This is the luxury layer. Weddings, festivals, parties. People want clean, upscale units and they will pay for them. The data shows it plain: the search "luxury porta potty rental nj" ran a 23 percent click-through rate in this account. That is more than double the campaign average. When someone types "luxury" in front of a toilet search, they are ready to spend, and the lead still only cost $7.68.

Emergencies and disasters. Storms, floods, a water main break, a failed septic system. Sudden, non-negotiable need. These are the least price-sensitive buyers of all, because the alternative is having no facilities. The volume is spiky, but every one is a fast, high-intent booking.

One account, three kinds of buyer. You do not have to pick. The ads catch all three.

The best keyword is not the cheap toilet

Here is the one that pays the bills. The single best-converting keyword in the whole campaign is not the basic porta potty. It is the restroom trailer.

"Toilet trailer rental company" brought in 53 conversions at $13.17 per lead over 90 days. Restroom trailers are the climate-controlled, upscale units people book for weddings and nice events. Same cheap click, far bigger job.

The pattern repeats on every trailer term. "Toilet trailer rental nj" at $11.77 a lead. "Portable restroom rental" at $13.21. "Bathroom trailer rental" as low as $8.28.

So the cheapest lead source in home services also has a high-ticket upsell built right into it. You advertise the whole spread, from the basic single unit to the luxury trailer, and let the searcher tell you which one they came for.

The costliest mistake: starving a winner

Now look at the one number that is not where it should be.

Impression share on this campaign is 13.8 percent. Impression share is the share of searches where your ad could have shown that it actually showed. At 13.8 percent, this campaign is missing roughly 86 percent of the searches it is eligible for.

That is not because the ads are weak. A 10.8 percent click-through rate and a 19.4 percent conversion rate tell you the ads are excellent. It is missing those searches because the daily budget runs out. It is capped at about $40 a day. Every day it hits that cap, the next person who searches "porta potty rental" sees a competitor instead.

This is the most common mistake I see owners make with a good campaign. They set a small budget to be safe, it works, and then they leave it there for years.

But a proven $13 lead machine is the last place to be cautious. When your cost per lead is already this low and your conversion rate is already this high, more budget mostly buys more of the same. Not worse leads. More of the good ones, until you approach the edge of real local demand.

The move is not to spend recklessly. It is: prove the number first, which this account has done at 275 leads and $12.93 each, then step the budget up and watch the cost per lead. Keep scaling as long as it holds. That is exactly the path this client took to more than double their spend.

Find the winner, then feed it. A low cost per lead with a low impression share is not a finished campaign. It is a signal you are leaving money on the table.

Even the specialists set the bar higher than $13

There is a small cluster of agencies that do nothing but porta potty and toilet-rental marketing. They publish their case studies proudly, and those are the best third-party benchmark you will find for this niche.

One case study advertises "$22 toilet rental leads." Another shows "40+ rental leads a month," which pencils out to around $33 a lead.

Those are their wins. Their headline numbers. This account is quietly running at $12.93, roughly half of what the specialists advertise as good.

That tells you two things. The benchmark itself is soft, because almost nobody has pushed this category to its floor. And the gap between good and great here is not some secret only a specialist holds. It comes down to account structure, the right keywords, and not starving a winner.

Who should not run these ads

I will be straight with you, because most articles like this will not.

These niches are so profitable that it is worth a shot for just about anybody who needs more customers. Porta potty especially. The auction is wide open. You are not walking into a knife fight the way you would in restoration or plumbing.

There is one exception. A really competitive area combined with a really small budget. If you are in a dense market where a few big operators are already bidding hard, and you can only put a little money in, that is a case we would just have to look at together before promising anything.

But that is rare here. This niche in particular is very noncompetitive. For most owners reading this, the question is not whether it works. It is how fast you want to grow.

The bottom line

Twelve dollars and ninety-three cents. That is what it costs this client to make the phone ring. They found us, they doubled down, and now their biggest problem is capacity.

If you own a porta potty company, a septic company, or something similar, and you have been curious about Google Ads, it is probably worth taking a second look.

Your five-minute checklist

1. Track your real cost per lead. Add up what you spend on ads in a month and divide by the number of calls and forms it produced. That one number tells you if the machine is working.
2. Check your impression share. If your cost per lead is low and your impression share is under about 40 percent, you are starving a winner. That is the single fastest fix in the account.
3. If the number holds, feed it. When a campaign proves a low cost per lead, step the budget up and watch the cost per lead as you go. Scale as long as it stays low. Stop when it starts climbing. That is the whole discipline.
