Google Ads and Meta Ads are not competitors — they are complementary tools that solve fundamentally different problems. Google captures existing demand from people actively searching. Meta creates new demand by reaching people based on interests and behavior. This guide gives you the data to allocate your budget correctly between the two platforms.

Fundamental difference: Intent vs interest
Google Ads is intent-based marketing. The user has already identified a need and is actively searching for a solution. When someone types "best CRM for small businesses" into Google, they are in an active buying process. Your ad answers an existing question.
Meta Ads (Facebook and Instagram) is interest-based marketing. The user has not necessarily identified a need — they are scrolling through their feed. Your ad must capture attention, spark interest, and generate demand where none existed before. This is a fundamentally different mechanism.
This difference has enormous implications for strategy. Google Ads is like standing at the checkout counter and offering your product to people who have already decided to buy. Meta Ads is like setting up a booth at a market and convincing passersby that they need what you are selling. Both work — but they require entirely different approaches.
Targeting: Keywords vs audiences vs lookalikes
Google Ads targets primarily through keywords. You bid on specific search phrases and appear when someone searches for them. In addition, Google offers audiences based on purchase intent (in-market audiences), demographics, and remarketing lists. Performance Max campaigns combine all of Google's surfaces with machine learning-driven targeting.
Meta Ads uses demographic, behavioral, and interest-based targeting. You can reach people based on job title, interests, life events, and online behavior. The most powerful feature is lookalike audiences — where Meta finds new users who resemble your existing customers. Meta reports that lookalike audiences typically deliver 30–50% lower CPA than broad targeting (Meta Business, 2025).
Google has broader reach at the moment of purchase. Meta has deeper insight into users' interests and behavior outside the buying context. For B2B, Google's in-market audiences are often more precise, while Meta's detailed demographic data can be valuable for reaching decision-makers based on job title and industry.
Ad formats: Search and Shopping vs feed, stories, and reels
Google offers text ads in search (responsive search ads), Shopping ads with product images and prices, display ads across millions of websites, YouTube video ads, and Performance Max campaigns that automatically cover all surfaces. The strength is format breadth — from intent-based search to visual advertising.
Meta offers image ads, video ads, carousel ads, stories ads, reels ads, and collection ads across Facebook, Instagram, Messenger, and Audience Network. The strength is the visual formats and the native experience — ads flow naturally into the user's feed.
For products that sell visually — fashion, food, design, travel — Meta typically achieves better engagement rates. For services and products that sell on functionality — software, consulting, industrial — Google's text-based search ads are often more effective because they directly answer the user's question.
Cost benchmarks by industry
Average CPC in Google Ads varies enormously by industry. WordStream (2025) reports the following global averages: legal — $6.75, insurance — $5.85, finance — $4.57, e-commerce — $1.16, B2B — $3.33, technology — $3.80, real estate — $2.37. In Nordic and Western European markets, CPCs typically run 20–40% above these global averages due to higher purchasing power and lower search volume.
For Meta Ads, Statista (2025) reports a global average CPC of $0.94, with CPM (cost per thousand impressions) at $12.07. In Nordic markets, we typically see CPCs of $0.50–$1.50 for most industries, with CPMs between $8 and $20. B2B advertising on Meta typically has higher CPC than B2C due to narrower audiences.
It is important to look beyond CPC at cost per conversion and return on ad spend (ROAS). Google Ads has a typically higher CPC but also a higher conversion rate (4.40% for search according to WordStream, 2025), while Meta has lower CPC but also a lower conversion rate (typically 1–3% depending on industry and funnel stage).
- Google Ads average CPC (Western markets): $2–$15 for commercial keywords, up to $50+ in finance/insurance
- Meta Ads average CPC (Nordic markets): $0.50–$1.50, CPM $8–$20
- Google conversion rate (search): 4.40% average (WordStream, 2025)
- Meta conversion rate: 1–3% depending on industry and funnel stage
Conversion paths: Direct response vs awareness and retargeting
Google Ads typically has a shorter conversion path. The user searches, clicks, and converts — often in the same session. For search ads, Google reports that 50% of conversions happen within 24 hours of the click for e-commerce (Google, 2024). This makes Google the preferred platform for direct response campaigns.
Meta Ads has a longer and more complex conversion path. The user sees an ad, perhaps engages, visits the website later, sees a retargeting ad, and eventually converts. Meta reports that the average buying journey involves 3–5 touchpoints (Meta Business, 2025). Attribution modeling is therefore critical for understanding Meta's actual value.
This means you cannot directly compare last-click conversions between platforms. Google will almost always look better in last-click attribution because it is where purchase intent is captured. Meta's value often lies in having created the demand that Google then captures. Use data-driven attribution to see the full picture.
B2B vs B2C: Which platform performs best?
For B2C — especially e-commerce, subscription services, and consumer products — Meta is often the most cost-effective channel for acquiring new customers. Meta's visual formats and broad demographic data make it possible to reach consumers based on lifestyle and interests. Instagram Stories and Reels have particularly strong conversion rates for B2C (Meta, 2025).
For B2B, Google Ads is typically stronger because the buying process often starts with a specific search. When a procurement manager searches for "ERP system for manufacturing," the Google ad is the natural point of contact. LinkedIn is often a better B2B platform than Meta, but Meta can work well for brand building and top-of-funnel even in B2B.
The exception is B2B companies selling to small businesses and solopreneurs. This audience is often more active on Facebook and Instagram than on LinkedIn, and Meta can deliver lower CPA than Google for this segment. Accountants, consulting services, and SaaS for SMBs often find success with Meta Ads.
E-commerce: Shopping Ads vs Dynamic Product Ads
Google Shopping Ads are the gold standard for e-commerce. They display product images, prices, and store names directly in search results. Statista reports that Shopping ads account for 76% of all retail spend in Google Ads and generate 85.3% of all clicks on retail ads (Statista, 2025). ROAS for Shopping campaigns in Western Europe typically ranges between 400% and 800%.
Meta's Dynamic Product Ads (DPA) automatically show relevant products from your catalog to users based on their browsing behavior. DPA is especially effective for retargeting — showing products to people who visited your website without purchasing. Meta reports that DPA delivers on average 34% lower CPA and 38% higher ROAS than static ads (Meta Business, 2025).
The optimal e-commerce strategy uses both: Google Shopping captures active purchase intent (the user searches for a specific product), while Meta DPA drives product discovery and retargeting of website visitors. Together, they cover the entire buying journey from discovery to purchase.
Retargeting strategies on each platform
Google Remarketing operates primarily through the Display Network and YouTube. You can target users who visited your website, viewed specific products, or started but did not complete a conversion. Google also offers Customer Match, where you upload customer lists to reach existing customers with tailored messaging.
Meta Retargeting is arguably the platform's strongest feature. You can build audiences based on website visits, engagement with Facebook/Instagram content, video views, and in-app actions. Meta's pixel and Conversions API provide detailed behavioral data enabling highly segmented retargeting.
An effective cross-platform retargeting strategy uses Meta for early retargeting (1–7 days after visit) with visual content that reminds the user of the product, and Google Display/YouTube for late retargeting (7–30 days) with a more direct call to action. This combination keeps the brand visible without overwhelming the user on a single platform.
Budget allocation: When to spend where
Budget allocation between Google and Meta should be driven by three factors: industry, goals, and funnel stage. Use our ad calculator for budget planning. As a starting point, we recommend the following splits based on objectives: for direct sales and leads — 60–70% Google / 30–40% Meta. For brand building and new audience reach — 30–40% Google / 60–70% Meta. For e-commerce with a broad catalog — 50% Google Shopping / 30% Meta DPA / 20% Google Search.
Adjust based on data. After 4–6 weeks of parallel campaigns, you have enough conversion data to calculate CPA and ROAS per platform. Shift budget toward the platform with the best profitability, but always maintain a minimum allocation on the other to avoid losing attribution data.
Remember that seasonality affects allocation. During peak seasons (Black Friday, holidays, promotional periods), Google allocation should increase because search volume rises dramatically. During off-peak, Meta allocation can increase for brand building and filling the top of the funnel with new prospects.
- Direct sales/leads: 60–70% Google / 30–40% Meta
- Brand building: 30–40% Google / 60–70% Meta
- E-commerce: 50% Google Shopping / 30% Meta DPA / 20% Google Search
- Adjust quarterly based on CPA and ROAS per platform
Full-funnel strategy: How Google and Meta work together
The most effective advertiser strategy uses Meta for the top of the funnel and Google for the bottom. Meta creates awareness and interest through visual content, video, and storytelling. Google captures the demand that Meta creates through search and Shopping ads.
In practice, this looks like this: Meta runs video and image advertising to broad interest audiences. Users who engage are retargeted with more product-specific content. When these users later search on Google (research shows that 65% do so within 7 days of seeing a social ad, according to Think with Google, 2024), Google ads capture them with a direct offer.
The key is sharing data between platforms. Use UTM parameters consistently, implement conversion tracking on both platforms, and analyze the complete conversion path — not just the last click. Companies that do this typically see 20–30% better total ROAS than those optimizing platforms in isolation (Forrester, 2025).
