Paid Media on Google and Meta: how to turn budget into real results

There is a question we get quite often: is digital advertising worth it? The honest answer is: it depends on how it is managed. Advertising on Google and Meta can be the highest-return channel in your entire marketing strategy. Or it can be a hole through which budget disappears without a trace. The difference is not in the platforms. It is in who manages them and with what judgement.

What Paid Media is and what it is for

Paid Media is any form of digital advertising you pay for to appear in front of your audience. In digital marketing for businesses with an online presence, the two most relevant platforms are Google Ads and Meta Ads (Facebook and Instagram), and they operate with completely different logics.

Paid advertising covers functions SEO alone cannot:

• Results from day one: unlike SEO, which works on week-long timelines, a well-configured campaign generates traffic and sales from the moment it goes live.
• Precise targeting: you can reach exactly who you want, by location, age, interests, purchase behaviour or search terms.
• Controlled scalability: if a campaign works, increasing spend multiplies results in a predictable way.
• Visibility at key moments: launches, seasons or specific campaigns where organic SEO cannot arrive in time.

Google Ads: capturing people already searching

Google is the high-intent channel by definition. When someone types into search what you sell, they are already halfway to purchase. That makes Google Ads especially efficient at the bottom of the funnel, where the goal is to convert existing demand into real transactions.

2026 market data places average ROAS on search campaigns between 6 and 8—that is, for every euro invested, between €6 and €8 in revenue is generated. But that figure varies widely by sector, campaign setup and destination site quality.

Google Ads campaign types

• Search: text ads that appear when someone searches on Google. The most direct format to capture purchase intent.
• Shopping: product listings with image and price in the results. Essential for ecommerce; it requires correct Google Merchant Center setup.
• Display and YouTube: visual formats to generate reach and brand recognition, generally with lower ROAS but high impact on awareness.
• Performance Max: automated campaigns that distribute budget across all Google channels. Very powerful when there is enough conversion data.

Working Google Ads well means far more than switching campaigns on: prior search-intent research, correct conversion tracking setup (including assisted and cross-device conversions), continuous optimisation of search terms and landing pages, and Google Merchant Center integration for ecommerce accounts.

Meta Ads: where demand is built

Meta (Facebook and Instagram) operates on another logic. The user is not searching: they are browsing. That makes it the ideal channel to generate demand, build brand awareness and reach audiences that do not yet know they need you.

In ecommerce, average ROAS on Meta sits around 2.87 for standard accounts. But the best results, with well-structured campaigns and quality creatives, consistently move between 3.5 and 5. Meta Advantage+ campaigns show performance about 22% above manual setups, which shows how important it is to understand automated systems and know when to give them room and when to intervene.

What makes a Meta account work well

• Clear funnel structure: prospecting to reach new audiences, retargeting to recover those who already showed interest, retention to reactivate existing customers.
• Creatives that stop the scroll: on Meta, the biggest risk is not budget but creative. A strong 15-second video can change the CPA of an entire campaign.
• Solid conversion signals: well-configured pixel, correct events, Conversions API active to offset privacy tracking limits.
• Systematic testing: the accounts that convert best are those that test formats with judgement and extract learnings from every test.

How performance is measured

The main metrics we use to evaluate the health of a paid account are:

• ROAS (Return on Ad Spend): revenue generated for each euro invested in advertising. The most direct efficiency metric.
• CPA (Cost per Acquisition): how much it costs to get a conversion (sale, lead, signup). Its evolution over time shows whether the account is improving.
• CTR (Click-Through Rate): percentage of users who click the ad. An indicator of message and creative relevance.
• CPM (Cost per thousand impressions): an early efficiency signal on Meta; a high CPM can indicate audience saturation or weak creatives.
• Landing conversion rate: because an ad can work perfectly and the destination page ruin the result.

In the Copines case, results after three months of integrated management were: ROAS 8.5 on Google Ads and 6.48 on Meta Ads in May, with CPA reductions of 53% and 35% respectively. These are not lab numbers. They are the result of iterating, measuring and deciding with real data.

Both platforms together: a sum that multiplies

The biggest mistake many advertisers make is managing Google and Meta as if they were independent channels. In reality they work as a system: Meta builds brand awareness and latent demand; Google captures that demand when it activates. Separating analysis of the two channels is reading only half the story.

When we manage both platforms for the same client, the first step is always full setup: pixels, conversions, attribution, audience audit. Without that base, optimisations have nowhere to stand.

Digital advertising is not expensive or cheap. It is efficient or inefficient. And that difference is made by management.
