Ex-Google Employee Reveals Secrets to Profitable Ads

I had Peter Guba on Marketing by Design recently. He drove over six hours from Michigan to Columbus to record the episode in person, which I still can't get over. Most guests are happy to do it on Zoom. Peter showed up.

We met at a conference in Florida earlier this year and became fast friends. The kind of conversation where you stop talking shop for a minute and trade actual notes on what it's like to build something. So when he agreed to come down for the show, I knew the conversation would be good. What I didn't expect was for him to flip a switch in my brain about how I think about paid ads, and by extension, how I think about everything that lives upstream of them.

If you run a B2B company, or you market for one, this is the conversation you've been waiting for somebody to have honestly.

Eight Years Inside the Machine

Before Peter founded Profit Mill, he spent nearly a decade inside Google. He worked across three different teams there. He managed more than a thousand ad accounts, ranging from first-time founders trying paid search for the first time to global brands like Air Canada and Four Seasons running fifty million dollars a year on the platform.

Most agency owners talk about Google Ads from the outside in. They've read the documentation, taken the certifications, run a few accounts. Peter spent eight years on the other side of the glass watching the actual patterns that drive results, the ones that don't show up in any blog post.

That's the part of his background that matters most to me, and it's the part most B2B founders should care about too. There's a big difference between someone who has read about how a platform works and someone who has watched a thousand companies succeed or fail on it in real time.

After leaving Google, Peter started Profit Mill in 2022. Today his agency works with companies like You.com, RunPod, EliseAI, Forum Ventures, and Paraform. The thesis is simple. Turn ad spend into actual revenue, not vanity metrics.

You can read his full background on LinkedIn if you want the resume. The short version is, when Peter talks about Google Ads, you should probably listen.

The 50/50 Truth Most Agencies Won't Tell You

Halfway through our conversation, I asked Peter a question I've been chewing on for a while. When you're running paid ads, how much of the result comes from the technical setup versus the offer itself? Like, the home run hook, the value prop, the thing on the page that actually makes someone want to click and convert.

His answer: fifty-fifty. You can't really separate them.

He explained it like this. If you have a great setup but a mediocre offer, or a website that doesn't position you well, no amount of campaign optimization is going to fix that. He can run the same playbook that's crushing it for his other clients, and the results just won't land. Because the playbook isn't the problem. The thing being advertised is.

The flip side is also true. You can have the best offer in the world, the cleanest positioning, the most compelling pitch on your homepage. If your ad setup is broken, if your tracking is wrong, if you're bidding on the wrong intent, none of that gets seen by the right people.

This sounds obvious when you write it down. But almost nobody operates like they believe it.

What founders usually do is pick a side. Either they think paid ads is a tactical problem (just hire someone better, run more tests, lower the CPA), or they think it's a brand problem (we need a new website, new messaging, a rebrand). Peter's view is that it's always both, in roughly equal measure, and the moment you decide it's only one, you've already lost.

Why Most B2B Companies Kill Ads Too Early

There's a pattern Peter has seen play out a thousand times. A B2B company decides to try Google Ads. They get the campaign live. They give it a couple of months. The leads aren't great. They shut it down. Then they tell themselves paid search doesn't work for their industry.

What actually happened is they ran a bad setup with not enough budget to generate meaningful data, drew a conclusion from noise, and walked away.

Years ago you could afford to learn that way. Clicks were cheaper. Competition was lighter. The platforms were more forgiving. Today none of that is true. The cost of getting it wrong has gone up, and the runway you need to figure it out has gotten longer. Most companies are still operating on a 2019 budget with 2026 economics.

Peter's clients don't fall into this trap because by the time they hire him, they've already done the foundational work of validating that paid ads can work for their business. The bigger problem he sees is companies who haven't done that work, decided ads don't work for them based on one bad attempt, and now refuse to try again.

If that's you, the honest answer is your last attempt probably wasn't a fair test.

What "Ready for Paid Ads" Actually Looks Like

I asked Peter what his ideal client looks like. The answer was specific.

His best clients are companies that are already running paid ads, already spending a meaningful amount of money, and have validated that the channel works for their business. They've gotten some value out of it. They know enough to know they want more. That eliminates the biggest risk in any new engagement, which is launching paid ads from zero for a company that hasn't proven the channel is right for them.

When somebody comes to him without that history, he can make educated guesses. He looks at cost per click, at competitors, at the quality of the website, at deal size and close rates. He can form a reasonable hypothesis about whether paid ads will be profitable. But he was honest with me on the show. If he had to predict every time, he'd lose more often than win. Some businesses are surprisingly profitable on paid search. Others, you'd swear should crush it, and they don't.

That's a useful thing to hear from someone who's been doing this for a decade. It means the question "is paid ads right for my business" isn't one you can answer from the outside. You answer it by running a real test, with the right setup, the right offer, and enough budget to actually learn something.

If you're not willing or able to do that, paid ads probably isn't your next move. There's no shame in that. There's a lot of shame in pretending otherwise.

The Message Discipline Most Founders Skip

Toward the end of our conversation, Peter shared a piece of advice he picked up from Sabri Suby that completely reframed how he markets Profit Mill.

Suby's point was this. Whatever your hook is, your single sentence positioning statement, you should keep saying it long after you're sick of saying it. Because there are infinite people out there who have never heard you. Every time you think "I've said this too many times," somebody is hearing it for the first time. Politicians do this. Drain the swamp. Three words. People still remember it years later.

Peter's version of that is "profitable paid ads by an ex-Googler." Five words. He puts it on his homepage. In his LinkedIn headline. In every conversation. He used to feel self-conscious about leading with the Google background after he left, like maybe he should drop it. Then he heard Suby's advice and stopped second-guessing.

I think about this a lot in my own work. Founders are constantly tempted to refresh their messaging, complicate it, make it sound smarter. The discipline is the opposite. Find the simple sentence that actually sells your business and repeat it until your customers can repeat it back to you.

What This Means for Your Website

Here's where I'll plant my flag.

If Peter is right that the offer is half the equation, then your website is half of half, which is to say it matters a lot. The homepage, the landing pages, the bottom-of-funnel service pages. That's where your offer lives. That's what the ad is sending traffic to. If your site doesn't pull its weight, your ads will never look profitable, no matter who's running them.

This is exactly the work I do at MMG Design. I build conversion-focused websites and marketing systems for mid-market B2B and healthcare companies, and the most common pattern I see is companies investing real money in paid ads while their website silently kills the conversion rate. They blame the ads. They blame the agency. The website was never the suspect, and it should have been the first one questioned.

If your ads aren't working and you've already changed agencies more than once, the next thing to look at is what happens after the click. That's almost always where the leak is.

If you're looking for a starting point, I put together a Visual Swipe File of high-converting websites so you can see what good actually looks like. It's free.

Listen to the Full Conversation

Peter and I covered a lot more than I could fit in this article. We got into how he's automating the back end of his agency with AI, why account managers will be the last truly valuable human role in agency work, the all-nighter that started the whole automation push, and where the name Profit Mill actually came from. It's one of my favorite conversations I've had on the show this year.

You can listen to the full episode of Marketing by Design wherever you get your podcasts. If you want to learn more about Peter or work with him directly, you can find him at Profit Mill or connect with him on LinkedIn.

And if your B2B website is the thing holding your paid ads back, you know where to find me.
