Measuring ROAS and return across ad platforms

Introduction: why old-school "click counting" no longer works

Every founder and marketing lead faces one burning question today: "Where is my money working best right now?"

A few years ago you could still rely on cheap clicks and mass traffic; today we operate in a harsh post-cookie reality shaped by Apple's iOS 14.5+ privacy changes . It is time to admit it: the "marketing 101" textbook rules of 2021 and linear targeting methods are no longer sustainable.

Instead of chasing outdated vanity metrics (lots of clicks or reach), the long-term focus has to be on one indicator: real profitability. Maison Mint is a data-driven boutique agency focused on clear business results, bringing its clients on average a 4x ROAS (return on ad spend), and up to 11x in the best cases (our own account data, results vary). Before we dive into the numbers, a reminder of the foundations in our piece on what marketing is in today's fast digital environment.

So how do you navigate the new campaign reality? Let us define the Google Ads vs Meta landscape through the platforms' fundamental differences:

• Google Ads is today's "yellow pages": the user arrives with a clear purchase intent. They have a specific problem and want an immediate solution. Your job is to be the first choice at the right moment.
• Meta (Facebook and Instagram) is the lively "café sandwich board": people come here for entertainment and social connection. Your ads have to catch attention, create demand and spark an interest that often turns into a purchase only later.

Because the platforms differ in nature, they need a completely different approach and professional campaign setup.

As the global Think with Google consumer analyses and HubSpot's marketing statisticsboth stress, the brands that win today are the ones that can measure the return on their investments precisely. This article puts the number-based truth about ROAS optimization on the table. We skip the assumptions and focus on how to optimize your performance marketing campaigns so that every euro works as hard as possible.

The technical reality in 2026: AI-driven campaigns (PMax and Advantage+)

We have reached the phase where micromanagement and manual campaign setup give way to machine learning. The core of a successful strategy is no longer finding a specific interest group but giving the algorithms a quality dataset.

Interest-based targeting vs broad targeting

For years the golden rule of Meta ads was detailed interest-based targeting. Today Meta's machine learning has become smart enough that over-narrowing can hurt results. Broad targeting analyzes millions of data points in real time and finds the user who is ready to buy faster than manual rules.

This shift is driven by Advantage+ ads, which test creative dynamically and deliver the right message personally to the right person, blurring the lines between Feed, Stories and Reels.

Google Performance Max (PMax): beyond search

A similar revolution is happening in Google's ecosystem. Google Performance Max pulls Google's entire inventory (Search, Display, YouTube, Gmail, Maps) under one goal-based campaign. The marketer's role here is technical data input, defining conversions and supplying outstanding creative.

The importance of first-party data and the Conversions API (CAPI)

Tightening browser privacy rules mean that first-party data (customer data, CRM) has become a resource worth its weight in gold. For the algorithms to deliver a high ROAS, it is critical to use the Meta Conversions API (CAPI) and Google Enhanced Conversions.

Server-side tracking sends data straight from the store's server to the platform, bypassing ad blockers and making sure every valuable action gets back to the algorithm without errors.

The numbers: differences between Google Ads and Meta

Smaller European markets are unique in their compactness. Drawing on Maison Mint's experience serving numerous clients across the Baltics and the Nordics, we see clear patterns in local buyer behavior. Our Google Ads management is always based on real local data.

Compared with the large Western markets, the cost per click in smaller EU markets is often lower, but the final conversion cost depends directly on landing page quality and trust. (Ranges from our own accounts, illustrative.) Datareportal 2024 confirms high social media usage across Europe, making Meta an ideal channel for growing brand awareness.

Omnichannel synergy: how Meta and Google work hand in hand

Maison Mint's approach does not treat these platforms as competitors but as strategic partners. When the systems are integrated, they create a synergy that lifts ROAS and long-term customer value.

A typical purchase journey starts on Meta (demand creation) and ends on Google (demand capture). The user sees an ad on Instagram, a memory trace forms, and days later they search for the brand name on Google. This leads to growth in branded search volume, one of the surest signs that a marketing strategy is working.

The budget split formula for SMEs

In a smaller market, ROAS optimization needs a strategic decision tree to avoid fragmenting the budget across too many small campaigns.

• The 70/30 split in e-commerce: for a new product, put 70% into "push" channels (Meta) to create demand and 30% into "pull" channels (Google) to capture it.
• B2B strategy: put 70% into Google to capture specific searches and 30% into Meta for retargeting, to stay on decision-makers' radar through the long sales cycle.

To secure long-term profitability, paid advertising has to be supported by organic visibility. Our Pinnly platform is built for SEO plus GEO, securing visibility in AI engines such as ChatGPT and Google AI Overviews. See our SEO servicesto reduce your long-term dependence on the cost per click.
