Google Shopping for Shopify: Step-by-Step Setup (2026)

Google Shopping is the highest-intent ad format in Google's network. People searching "buy [product]" see your image, price, and rating. Filtered, qualified, ready to buy.

Setup is straightforward. Optimization separates winners from spenders.

TL;DR

Setup phases:

1. Create Google Merchant Center account.

2. Verify and claim your domain.

3. Connect Shopify via the Google channel.

4. Submit your feed.

5. Fix disapprovals.

6. Set up shipping and tax in MC.

7. Connect Google Ads → run Performance Max or Standard Shopping campaign.

Step 1: Merchant Center account

Go to merchants.google.com → Sign up.

Fill in:

Business name.

Business country: Philippines.

Time zone: PHT.

Use the same Google account that will host your Google Ads.

Step 2: Verify your domain

In MC → Settings → Business information → Website.

Verify via:

HTML tag (paste in your Shopify theme.liquid).

HTML file upload.

Google Tag Manager.

Google Analytics.

Once verified, claim the URL (locks ownership to your MC).

Step 3: Connect Shopify

In Shopify → Settings → Sales Channels → Google & YouTube → install.

Connect to Google Merchant Center → Authorize.

Shopify auto-syncs your products to MC. No manual feed needed.

Step 4: Configure feed in Shopify

In the Google channel, configure:

Which products to include (all, or specific collections).

Default GTIN settings.

Default category mappings.

Brand attribute mapping.

Image preferences.

For PH stores: set "Country: Philippines" and "Currency: PHP."

Step 5: Wait for feed processing

After submission:

Most products approved within 24 hours.

Some require additional review (3–5 days).

Disapprovals shown in MC's Diagnostics tab.

Step 6: Fix disapprovals

Common PH-specific issues:

Missing GTIN

Many PH brands have no GTIN (Global Trade Item Number). Solution:

In Shopify → product → Google channel → set "Identifier exists: false."

Add a manufacturer name and your brand name (required when no GTIN).

Image quality

Minimum size: 100x100px.

Recommended: 800x800px or larger.

White or transparent background preferred.

Single product (no collages, watermarks, or text overlays).

Pricing inconsistency

The price in your feed must match the price on your live website. Even ₱5 difference triggers disapproval.

Fix:

Don't run a sale via discount code only — adjust your product page price.

Or use Shopify's "compare at" price properly so MC reads correct price.

Shipping configuration

MC requires shipping settings. Set up:

MC → Shipping → Add shipping service.

Define rates per region (Metro Manila, Provincial).

Match your Shopify shipping setup.

If your Shopify shipping is more complex than MC's options, simplify or use Shopping Computed Shipping.

Step 7: Connect to Google Ads

In MC → Settings → Linked accounts → Google Ads → Link.

Once linked, you can create:

Performance Max campaign (recommended).

Standard Shopping campaign (more manual control).

Smart Shopping (legacy, mostly migrated to PMax).

Step 8: Launch first campaign

For most PH ecom stores: start with Performance Max.

Settings:

Budget: ₱2,000–₱5,000/day.

Target ROAS: don't set initially. Use Maximize Conversion Value.

Asset groups: organize by product theme.

Audience signals: optional.

Feed optimization (the lever most miss)

Once approved, optimize the feed for performance:

Title

Title is the most important attribute. Should include:

Brand

Product type

Key attribute (size, color, material)

Specific identifier

Bad: "Hair Oil"

Good: "[Brand] Vanilla Hair Oil 50ml Daily Serum"

In Shopify, title pulls from product name. Optimize product names with this in mind.

Description

First 160 characters matter most. Include keywords customers search.

Images

Primary image: clean white background.

Additional images: lifestyle, detail.

All high-res, no text overlays.

Product type / category

Set Google Product Category accurately. Wrong category = wrong searches matched.

Custom labels

Use custom labels (custom_label_0–4) to segment products in your campaigns:

custom_label_0: bestseller (yes/no)

custom_label_1: margin tier (high/mid/low)

custom_label_2: launch date (new/established)

custom_label_3: collection (skincare/makeup/accessories)

custom_label_4: AOV range

In Google Ads, you can then bid differently or build separate campaigns by these labels.

Common Shopping mistakes

1. Submitting feed and forgetting

Feed needs ongoing maintenance. Pricing, stock, and promotions all need feed updates.

2. Running one Shopping campaign with all products

Different products have different margins, AOVs, conversion rates. At minimum, separate by category.

3. Not using Custom Labels

Without labels, you can't segment campaigns by performance tiers.

4. Ignoring search query reports

Even Shopping campaigns benefit from negative keywords. Look at search terms; add irrelevant ones as negatives.

5. Bid strategy mismatched to data

Setting Target ROAS without enough conversion data. Start loose.

Promotions in MC

MC supports promotion tags for:

Free shipping.

Sale prices.

Bundle deals.

Set up promotions in MC → Promotions → New promotion. They show as a special promotion icon on Shopping listings.

Reviews integration

MC supports product reviews via:

Google Customer Reviews (free).

Third-party review aggregators (Loox, Stamped, Yotpo) — requires manual configuration.

Reviews appear as star ratings on Shopping listings. 4.5+ stars dramatically lift CTR.

What about Shopping Ads on Search?

Shopping ads also appear at the top of Search results when relevant queries are made. PMax handles both Shopping placement AND Search Shopping.

Reporting

In Google Ads:

Filter by campaign type → Shopping or Performance Max.

Look at:

- Spend by product.

- Cost per conversion.

- Conversion rate by product.

- Search terms (Shopping campaigns).

Identify top SKUs, push more budget there. Identify dead SKUs, pause or remove.

What to do this week

If you have a Shopify store but no Shopping campaign running:

1. Day 1: Create MC, verify domain, submit feed.

2. Day 2–3: Fix disapprovals.

3. Day 4: Set up shipping in MC.

4. Day 5: Create first PMax or Shopping campaign.

5. Day 7: Launch.

Most PH stores see Shopping become their highest-ROAS channel within 30 days.
