How to Run Facebook Ads and Google Ads Together (2026 Guide)
Learn how to run Facebook ads and Google ads together without wasting budget or creating attribution chaos. A practical unified workflow for SMB marketers managing both platforms in 2026.
Facebook Ads and Google Ads Together: The Complete Cross-Platform Strategy Guide
Most advertisers pick a side: Facebook Ads or Google Ads. The sophisticated ones run both — and they systematically outperform single-platform advertisers because they're capturing buyers at every stage of the purchase journey, not just one.
This guide explains how to run Facebook and Google Ads together as a unified system: how to split budget, which platform does what job, how to identify winning Meta creatives for Google Performance Max, and how to measure cross-platform performance accurately.

Why Run Facebook and Google Ads Together
The two platforms operate at fundamentally different stages of the buyer journey — which makes them complementary, not competitive.
Google Ads captures demand. When someone searches "best CRM software" or "running shoes size 10," they're actively evaluating options. Google captures this intent-driven traffic. The problem: there are only so many people searching for your product right now.
Facebook Ads creates demand. When someone scrolls their feed and sees your product, they weren't looking for it — but now they are. Facebook reaches people before they know they want your product. The problem: lower purchase intent at the moment of the ad.
Together, they form a complete funnel:
1. Facebook introduces your product to a cold audience
2. Interested users search Google to learn more and compare options
3. Google captures that research-mode traffic and converts it
Advertisers who run both consistently see Google's conversion rates improve — because Google is now capturing warm audiences that Facebook already primed, not just cold intent-driven searchers.

Budget Allocation Strategy
There's no universal split, but here are the patterns that work across different business types:
E-commerce (typical 60/40):
• 60% Facebook/Meta: Broad prospecting, lookalikes, retargeting
• 40% Google: Shopping campaigns, branded search, PMAX
Facebook drives the initial discovery; Google closes the sale when the buyer is comparison shopping.
B2B/SaaS (typical 30/70):
• 30% Facebook/Meta: Thought leadership, retargeting, lookalikes
• 70% Google: High-intent search terms, competitor campaigns
B2B buyers rely heavily on search when evaluating vendors. Google does more of the heavy lifting, but Facebook keeps your brand visible during the evaluation period.
Local services (typical 50/50):
• 50% Facebook/Meta: Local awareness, lead generation campaigns
• 50% Google: "Near me" and service-specific searches
Starting point rule: If you're unsure, start 70/30 in favor of whichever platform you have more performance history on. Let conversion data guide rebalancing over the first 60–90 days.

How to Identify Winning Meta Creatives for PMAX
This is where running both platforms creates a real competitive advantage. Meta's algorithm is excellent at finding what creative resonates with your audience — and you can use that intelligence in Google's Performance Max campaigns.
The testing workflow:
1. Run creative tests on Meta first. Meta's broad audience and creative-optimized feed make it the best A/B testing environment for visual content. Test 4–6 creative variants with a dedicated $20–$30/day budget for 7–10 days.
2. Identify the winners. Look for creatives with CTR above benchmark, above-average video view rates, or strong engagement signals. Anything performing 2x above average is a candidate.
3. Analyze why it won. Is it the hook (first 3 seconds of video)? The offer in the static image? The color palette? Understanding the "why" helps you repurpose intelligently.
4. Import the winning assets into PMAX. Take the winning video, the winning static image in the right ratios, and the winning headline variants. Load them into a new asset group. Your PMAX campaign now starts with proven creative instead of untested assets.
This approach means your Google Ads campaigns benefit from Meta's superior creative testing environment — you're not starting from scratch with every PMAX campaign.

Creative Repurposing Workflow
Meta and Google have different asset specifications, but the conversion is manageable:
Images:
• Meta feed: 1080×1080 (1:1) → PMAX square: 1200×1200 (1:1) ✓ Same ratio
• Meta feed: 1200×628 (1.91:1) → PMAX landscape: 1200×628 (1.91:1) ✓ Same ratio
• Meta stories: 1080×1920 (9:16) → PMAX portrait: 960×1200 (4:5) — requires crop
Videos:
• Meta: 1:1 or 4:5 square/portrait video, 15–60 seconds
• PMAX: 16:9 landscape preferred for YouTube, minimum 10 seconds
• Quick fix: Most Meta horizontal videos (1.91:1) work in PMAX. Vertical videos need reformatting.
Copy:
• Meta headline: 40 characters → PMAX headline: 30 characters (requires shortening)
• Meta primary text: 125 characters → PMAX description: 90 characters (requires editing)
• Strategy: Write PMAX-leng
