🛒 What is Standard Shopping?

The classic campaign, built on Google Merchant Center.

You control everything:

• The bids on each product
• Where your ads appear
• Which terms you exclude
• How much you spend on mobile vs desktop

✅ Why it’s good

• You see exactly what’s working
• You can optimise each product manually
• Ideal when you’re learning Google Ads
• 100% transparency on search terms

❌ Why it’s harder

• It takes management time
• Reach is limited to Search and the Shopping tab
• You have to optimise everything manually

🚀 What is Performance Max?

The “all-in-one” campaign. A single campaign across all of Google’s channels:

Where you appear	What it does
🔍 Search	Search results
🛍️ Shopping	Product listings
📺 YouTube	Video ads
🖼️ Display	Banners
📧 Gmail	Inbox
📱 Discover	Feed

✅ Why it’s good

• Google optimises automatically
• You reach everywhere with a single campaign
• The AI finds new audiences
• Fast scaling

❌ Why it’s harder

• You don’t see all the data
• It can “steal” brand traffic
• You need volume (min. 30 conversions/month)
• Limited control

🎯 When to use Standard Shopping?

Ideal for:

• ✓ You’re just starting out — you want to learn what converts
• ✓ Budget under €2,000/month — you need control
• ✓ Different margins across products — custom bids
• ✓ You want maximum transparency

💡 Real example: A client with 50 products and a budget of €1,500/month. We discovered that just 8 products accounted for 70% of sales. We raised the bids on those and cut them on the rest. The result? ROAS went from 3.2x to 5.8x.

🎯 When to use Performance Max?

Ideal for:

• ✓ Budget over €5,000/month — the AI has data to work with
• ✓ At least 30 conversions/month — for optimisation
• ✓ You want to scale fast — automation
• ✓ You have good assets — images, video, copy

💡 Real example: A fashion brand with a budget of €15,000/month. PMax found audiences on YouTube and Discover that we wouldn’t have found otherwise. The result? +47% revenue in 60 days.

🔥 The strategy that works: Hybrid

🏆 Our recommendation: Don’t choose one or the other. Use both strategically.

The ideal structure

Which campaign	What for	% of budget
Standard Shopping - Brand	Protecting your brand	20-30%
Standard Shopping - Top Products	Control over best-sellers	30-40%
Performance Max	Scaling and discovery	30-50%

How to implement it step by step

Step 1 → Run Standard Shopping for 2-3 months to gather data

Step 2 → Identify the winning products (20% drive 80% of sales)

Step 3 → Create PMax and exclude your brand from it

Step 4 → Adjust the monthly budget based on results

⚠️ Mistakes to avoid

Don’t do this:

Mistake	Why it’s a problem
PMax from the start	Without data, it spends inefficiently
Brand in PMax	”Steals” conversions that would have come anyway
Weak assets	Blurry images = poor results
Ignoring Search Terms	You waste 20-30% of your budget

📊 Metrics to track

What you measure	Standard Shopping	Performance Max
ROAS target	4-6x	5-8x
CPA	Per product (visible)	Aggregated
Conv. Rate	2-4%	1-3%
Control	Full	Limited

---

⚡ TL;DR — Quick summary

Situation	What to use
Small budget, you want control	Standard Shopping
Large budget, you want to scale	Performance Max
You want maximum results	Both, strategically

🎯 The golden rule: Start with Standard to learn. Add PMax once you have data. The combination delivers the best results.
