In 2024, Romanian online stores with sustained growth had an average of 3.2 active paid traffic sources. Those stagnating or declining depended on a single channel. It's not a coincidence: concentration on one channel means any algorithm change, CPC increase, or account suspension leaves you without revenue overnight.
How Do Google Ads, Meta Ads, and Email Marketing Work Together?
Google Ads
- Captures existing demand
- User is actively searching
- High purchase intent
- Higher CPC, direct conversion
- Works without creative content
Meta Ads
- Creates new demand
- User isn't actively searching
- Medium purchase intent
- Lower CPM, longer cycle
- Requires quality creatives
Email Marketing
- Monetizes existing list
- Already qualified audience
- Highest ROI per channel
- Near-zero marginal cost
- Requires previously built list
How Do You Allocate Budget Between Google, Meta, and Email?
There's no universal recipe, but there are empirically validated benchmarks for the Romanian market. An online store with a total budget of €1,000/month should start with an allocation of 60% Google, 30% Meta, and 10% email (for the platform and automations). As the email list grows, the email proportion grows with it.
This allocation isn't fixed. If Google Ads delivers ROAS 8 and Meta delivers ROAS 3, reallocate budget to Google. If Meta Ads creates awareness that feeds the email list and subsequently drives email conversions, Meta has a contribution underestimated by last-click attribution. Flexible allocation, adjusted monthly based on real data.
What Role Does Google Ads Play in an Omnichannel eCommerce Strategy?
In the omnichannel strategy for eCommerce, Google Ads has the role of capturing the demand that Meta Ads generates. A user sees a product on Instagram, searches for it on Google the next day. If you're not present in Google Shopping or Search for that product, your competitor takes the order.
Recommended Google structure in the mix: 70% budget on Shopping (Standard or Performance Max with a good feed), 20% on brand Search and high-intent categories, 10% on Display retargeting for site visitors who didn't convert.
How Do You Structure Meta Ads Correctly in an Omnichannel Strategy?
The most common Meta Ads mistake for eCommerce: a single conversion campaign that does everything. Mixed prospecting and retargeting means the algorithm optimizes for conversions but across audiences with different potential, with budgets that cannibalize each other.
The correct structure: a separate prospecting campaign (cold audiences, lookalike, interests) with a conversion objective but retargeting excluded, and a separate retargeting campaign (site visitors in the last 30 days, abandoned cart, product page viewers) with independent budgets.
Recommended prospecting/retargeting ratio for Meta: 70/30. If retargeting consumes more than 40% of the Meta budget, it means prospecting isn't feeding enough new traffic into the funnel. The retargeting audience gets exhausted and frequency becomes too high.
Why Does Email Marketing Have the Highest ROI and Why Is It So Often Ignored?
Average ROI of email marketing in eCommerce: €36–€42 per €1 invested (source: Litmus, 2024). By far the most efficient channel in cost terms, but it requires a prior investment: building the list. The list isn't built through paid advertising directly, but through lead magnets, site pop-ups, and email capture campaigns integrated into Meta and Google campaigns.
The automation flows that matter for eCommerce: welcome email with first-order offer (average conversion: 15–25%), 3-step abandoned cart email (average recovery: 10–15%), post-purchase email with upsell at 7 days (return rate: 8–12%), and seasonal campaigns for existing customers (ROAS: highest in the entire account).
What Metrics Do You Track in an Omnichannel Strategy to Measure Profitability Correctly?
The biggest obstacle in omnichannel is attribution. Last-click attribution distributes credit incorrectly, undervaluing top-of-funnel channels. The solution isn't perfect, but it's practical: use data-driven attribution in Google Ads (available at 300+ conversions/month), compare periods with and without active Meta campaigns, and track LTV trends of customers by first-acquisition channel.
Real ROAS = Total period revenue / Total advertising spend (all channels)
The metric that matters more than per-channel ROAS: total acquisition cost per new customer, calculated across all channels combined. A customer brought by Meta Ads at ROAS 2.5 who subsequently buys 4 more times from email has a real acquisition cost much lower than the Meta report shows.
Omnichannel doesn't mean being on every platform. It means the platforms you're on work together, not in parallel ignoring each other.
To understand how each channel covers a different funnel stage, read customer journey in eCommerce and how ads influence every stage. And to measure whether your channel mix is actually profitable, POAS vs ROAS shows why attributed revenue isn't the same as profit.
A paid media strategy without a clear funnel logic costs more than you think.
At DAFE Digital we don't launch isolated campaigns — we build acquisition systems. We identify the right channels for each stage of the buying decision, allocate budgets with logic and measure what matters: profit, not vanity metrics.
