Meta Ads + Google Ads: The Cross-Channel Playbook That Actually Works
Running both platforms in silos? You're leaving money on the table. Learn how unified attribution reveals the full customer journey and boosts ROAS.
The silo problem
Most advertisers run Google and Meta separately: separate budgets, separate reporting, separate "last click" wins. So when someone sees a Meta ad, then searches on Google and converts, Google gets the credit and Meta looks inefficient. You end up underfunding the channel that started the journey and overfunding the one that closed it.
Why unified attribution matters
Unified attribution (view-through and click-through across both platforms) shows the full path. You’ll often find that Meta is driving a large share of conversions that Google eventually closes — and that Meta’s "direct" ROAS is understated. Once you credit both touchpoints, you can reallocate budget to the true drivers instead of the last click.
A playbook that works
1. Connect both Google and Meta to a single reporting and optimization layer (e.g. AdvertisingSystems) so you see one journey.
2. Use a consistent attribution window (e.g. 7-day click, 1-day view) across both so you’re comparing apples to apples.
3. Create segments of "Google converters who saw Meta" and "Meta converters who saw Google" and use them for lookalikes and remarketing.
4. Set cross-channel budget rules: e.g. "If Meta’s attributed ROAS is above X, allow the AI to shift more spend from Google to Meta."
5. Review weekly: Look at assisted conversions and path reports, not just last-click. Adjust creative and audience based on where people actually enter and exit the funnel.
What you’ll see
Accounts that implement this typically see ROAS improve by 20–40% within 60–90 days, not because they spend more, but because they spend in the right place. Meta often gets a fairer share of budget; Google keeps closing intent. If you’re still optimizing each platform in a vacuum, this is the year to connect them.
