The Hidden Cost of Google's AI Search Revolution
Earlier this year, Google rolled out its Core Update.
It fundamentally expanded AI Overviews, making them the primary destination for searchers instead of a side feature.
The impact was immediate. 60% of searches now end without anyone clicking through to a website. The AI summary answers the question directly on Google's search page, so people never reach your site.
If you sell fashion, beauty, or accessories online, you felt this.
Why This Happened (And Why It Matters)
Google's algorithm change meant fewer people actually click through to individual brand websites. They get their answer from the AI summary and maybe see some shopping results, so they buy without ever finding you.
This wouldn't be a crisis if your business wasn't relying on Google search as your main way to get customers.
Before, people would search for what they wanted, find you, and buy. That was free traffic. Your cost to get a customer was just time and some basic marketing effort.
Now that's changed. And suddenly you need to pay (through ads) to get people you used to get for free.
The Problem That Looks Like A Solution
So you turn up your paid ad spending. Facebook (Meta), Google Ads, TikTok, you're running them all now.
And what confuses everyone? The ads seem to be working.
You look at your numbers and think: "My ads are profitable. I'm making money on them."
But you might not actually be.
Here's why: the ads are probably capturing people who would have bought from you anyway through Google search. You're not making new customers. You're paying to get customers you already had access to.
It's like this: before, a customer would search Google, find you, and buy. You spent €0. Now, a customer sees your ad on Facebook or Instagram, clicks it, and buys. You spent €20 to get them.
Same customer. Higher cost. Smaller profit.
Your ads look profitable because you're measuring them wrong.
How to Know If This Is You
Take a few minutes and think about these:
• Has your total number of new customers stayed roughly the same since March, but you're spending way more on ads? That's the problem.
• Did your inbox of inbound inquiries get quieter around March? That's Google search dropping.
• Are you making money on your ads, but less profit per order than you used to? That's because you're paying to get customers you could have gotten free.
• Did you notice you started relying way more on paid ads instead of people just finding you naturally? That's cannibalization.
If most of these sound like you, this is your situation.
What You Actually Need To Think About
Before you read any "tactics," understand this: the real problem isn't traffic. It's profit.
You need to know:
• How much profit are you actually making per order after paying for the ad? Not just "did the ad make money back," but did it make enough money?
• Are your ads bringing in people who have never heard of you (new customers), or people who already know you? These are completely different.
• What's the real cost to get one new customer, when you factor in everything?
These questions matter more than any tactic.
The Actual Fix
You have two paths:
First: stop relying on one channel.
You can't control Google. You can control where people find you. Build email lists. Show up on Instagram, TikTok, Pinterest organically. Get people to find you directly instead of through search. It takes longer, but it's yours.
Second: get smart about paid ads.
If you're going to spend money on ads, don't spend it trying to reach people who would have found you anyway. Spend it on people who wouldn't know about you otherwise. And only spend what you can afford while still making profit.
This means you need to know your numbers. Specifically, how much profit you make per product, and what you can spend on ads and still keep that profit.
What To Prioritize (Short Term Vs. Long Term)
Before you try to fix everything, understand what matters now and what matters later.
This month: figure out if this is actually your problem.
Use this Free Diagnostic Tool to run a quick health check. Calculate your profit per order and your blended performance. See if it matches the benchmarks below. This should take you an hour or two. If your numbers are healthy, you don't have a crisis. If they're not, move to the next step.
Next 4-8 weeks: test and measure selectively.
Don't overhaul everything. Pick one thing. If you think paid ads are cannibalizing organic, pause ads for your top-selling product category for two weeks and watch what happens to organic traffic. If organic bounces back, you found your answer. If it doesn't, paid might be adding real value.
At the same time, separate your ad spending into categories: new customer acquisition vs. retargeting vs. branded search. Measure each separately. You'll probably find that one is profitable and one is breaking even. Stop the one that's not working.
Months 3-6: build resilience.
Start building email lists (if you haven't), show up consistently on social media, and write content that your customers are actually searching for. This doesn't need to be perfect. It just needs to exist. These channels won't replace Google search tomorrow, but they will over time.
6+ months: think about growth differently.
Once you have multiple channels working (even if they're smaller), you can think about scaling. You're no longer dependent on one platform's algorithm. You can actually predict growth because you understand where it's coming from.
What To Do Next
You need a clear-eyed look at your actual numbers. Not what platforms tell you your Return on Ad Spend (ROAS) is. But what's actually happening in your business.
That's what the Measurement Guide is for. It walks you through figuring out if this is really your problem, and if so, what to test first.
The good news: you're not broken. You're just in a position where you have to get smarter about where your customers come from. And that usually leads to better business anyway.
How These Numbers Work
When you look at your marketing data, here's what actually matters:
Return on Ad Spend (ROAS)
• What it measures: How much money you make back for every Euro you spend on ads
• Why brands love it: It seems simple and clear
• The catch: It doesn't tell you if you're making profit. It just tells you if the sale was bigger than the ad cost.
• Formula: Total Money Made from Ads ÷ Total Money Spent on Ads
• Example: You spent €1,000 on ads and made €4,000 in sales. That's 4:1 ROAS (or "4x return")
• Benchmark: For fashion and beauty direct-to-consumer brands, anything above 2:1 ROAS might look good, but it only works if you account for your product costs. If your average product cost is €30 and you're selling for €80, and your ad cost per order is €25, you're only keeping €25 profit. A 3:1 ROAS becomes much less impressive.
• Real talk: This is why profit per order matters more than ROAS
Customer Acquisition Cost (CAC)
• What it measures: How much money you spend on marketing to get one new customer
• Why it matters: It shows you the real cost of growth
• Formula: Total Marketing Spend ÷ Number of New Customers You Got
• Example: You spent €5,000 on ads this month and got 50 new customers. That's €100 per customer (your CAC)
• Benchmark: For smaller fashion and beauty brands, a healthy CAC is typically between €20 and €60, depending on your product price and average order value. If your average product price is €50, a CAC of €40 means you're spending 80% of the sale just to get the customer. That leaves almost no room for profit. A CAC around €15 to €25 is more sustainable for smaller brands starting out.
• Why this matters more than ROAS: It tells you if getting new customers is actually affordable for you
Blended Performance (all channels together)
• What it measures: How much money you make from ALL your sales sources (organic search, email, ads, direct visits) compared to how much you spent on ads
• Why it matters: It shows you if your total business is actually growing, or if ads are just replacing organic
• Formula: Total Money Made (from everything) ÷ Total Money Spent on Ads
• Example: You made €100,000 total (from all sources) and spent €10,000 on ads. That's 10:1 blended performance
• Benchmark: A healthy blended performance for a direct-to-consumer brand is around 4:1 to 6:1. If your blended performance is trending downward month over month (so it was 5:1 last month and 4:1 this month), that's a red flag that ads are starting to cannibalize organic sales. If it's staying stable or improving, you're likely adding real growth.
• Real talk: If your ads look great but your blended performance is getting worse, that means ads are cannibalizing your free traffic
Profit Per Order (after ads)
• What it measures: How much actual money is left in your pocket after you pay for the product AND the ad
• Why it matters: This is literally all that matters. Is the business making money?
• Formula: Price Customer Paid − What It Cost You to Make It − What You Paid for the Ad
• Example: Customer pays €100. Product cost €30 to make. Ad cost €20. You keep €50.
• Benchmark: For a healthy sustainable business, you want to keep at least €15 to €30 profit per order (more if possible). If your profit per order is €5 or less, you're on a treadmill. You're generating sales but not actually building a business. If it's consistently €20 or above, you're in a good position to scale.
• Real talk: This is the only number that actually tells you if you should keep running that ad
