This Google Shopping Ads setup guide walks a first-time advertiser through every step: creating a Google Merchant Center account, building a compliant product feed, linking it to Google Ads, and choosing between Standard Shopping and Performance Max campaigns. Get the feed right first — most beginner mistakes happen before the first ad ever runs, not after.
What Google Shopping Ads Actually Are
Unlike text-based Search ads, Google Shopping ads show a product image, price, store name, and (often) review rating directly in search results — no keyword bidding on your end in the traditional sense. Google decides which searches to show your product for based on the data in your product feed, which is why feed quality matters more here than in almost any other Google Ads campaign type.
Step 1: Create a Google Merchant Center Account
Merchant Center is where your product catalogue lives before it ever reaches Google Ads. To set one up:
- Go to Merchant Center and sign in with a Google account (ideally a shared business account, not a personal one, so access can be managed later).
- Enter your business name, country, and website URL — this needs to exactly match your live e-commerce site.
- Verify and claim your website through one of Google’s methods (HTML tag, Google Analytics, Google Tag Manager, or a DNS record) — claiming is mandatory before ads can run.
- Set your shipping and tax/GST settings under Business information — Indian merchants need to configure GST-inclusive pricing correctly, since a mismatch between the feed price and displayed price is a common cause of disapproval.
Step 2: Build a Compliant Product Feed
Your feed is a structured file (usually a spreadsheet or an automated feed from your e-commerce platform — Shopify, WooCommerce, and Magento all have plugins for this) listing every product with specific required attributes:
- id — a unique product identifier.
- title — descriptive, keyword-relevant, but never promotional (no “SALE” or “50% OFF” inside the title field).
- description — accurate product details, matching what’s on the actual product page.
- link — the direct URL to that specific product page.
- image_link — a clean, high-resolution image with no watermarks or promotional overlays.
- price — must match exactly what’s shown on the live product page at checkout, including currency (INR).
- availability — in stock, out of stock, or preorder, kept current.
- brand, GTIN, or MPN — required for most product categories; missing these is one of the single biggest causes of feed disapproval for smaller Indian sellers using unbranded or locally sourced stock.
- google_product_category — Google’s own taxonomy, which helps your products surface for the right searches.
Most beginners underestimate how strict Google is about price and availability accuracy — even a small mismatch between the feed and the live page can get individual products (or the whole feed) disapproved.
Step 3: Link Merchant Center to Google Ads
Once your feed is approved:
- In Merchant Center, go to Settings and select “Linked accounts,” then link your Google Ads account (using its Customer ID).
- Approve the link from the Google Ads side as well — linking is a two-way confirmation.
- Your product feed will now be available to select when creating a new Shopping campaign in Google Ads.
If you’re also running or considering Search or Display campaigns, our Google Ads management services can help you sequence Shopping alongside other campaign types rather than running them in isolation.
Step 4: Choose a Campaign Type — Standard Shopping vs. Performance Max
Google Ads offers two main ways to run Shopping ads, and beginners should understand the trade-off before picking one:
- Standard Shopping campaigns — you set manual or semi-automated bids, and you can see which search terms triggered your ads. This visibility is valuable while you’re learning what actually converts, and it’s the easier campaign type to diagnose when something goes wrong.
- Performance Max (Shopping-focused) — Google’s machine learning automatically manages bidding and placement across Search, Display, YouTube, Gmail, and Discover using your product feed as the core asset. It typically performs better once there’s enough historical conversion data, but offers far less granular reporting, which can frustrate a first-time advertiser trying to understand what’s working.
A practical approach for most small businesses: run Standard Shopping for the first 3-4 weeks to understand baseline performance and fix any feed issues, then test Performance Max once you have at least 20-30 conversions of historical data for the algorithm to learn from. For a deeper look at when Performance Max makes sense, see our guide to a Performance Max Google Ads strategy.
Step 5: Set a Beginner Budget and Bidding Strategy
As general guidance based on the small Indian retailers we work with, a modest starting budget of INR 300-800 per day (roughly INR 9,000-24,000 per month) is usually enough to gather meaningful click and conversion data within 2-3 weeks, assuming a catalogue of 50-300 products. For very small catalogues, INR 200-400 per day is often sufficient to start. Two bidding approaches work well for beginners:
- Maximize Clicks — a safe starting point that spends your budget getting traffic while you gather conversion data, without requiring a conversion-value history Google doesn’t have yet.
- Target ROAS (Return on Ad Spend) — better once you have at least 15-20 conversions logged, letting Google’s algorithm optimise toward a specific return target rather than just clicks.
Common Feed-Rejection Mistakes to Avoid
- Price mismatches — the single most common rejection reason; the feed price must exactly match the live checkout price at all times.
- Promotional text in titles — “Buy 1 Get 1,” “Flat 30% Off,” and similar phrases inside the title or description field violate Google’s editorial policies; promotions belong in Merchant Promotions, not the product title.
- Missing GTIN/brand for branded products — required for most manufactured goods; using “N/A” or leaving it blank when a real GTIN exists gets flagged.
- Low-quality or watermarked images — stock photos with a logo overlay, or images under 100×100 pixels, are routinely disapproved.
- Landing page mismatches — the product link must lead directly to that specific product’s page, not a category page or the homepage.
- Missing return/refund policy on the website — Merchant Center checks for a visible, accessible returns policy page as part of account-level trust requirements.
Monitoring and Optimising After Launch
Once campaigns are live, check these weekly for the first month:
- Search terms report (Standard Shopping only) — add irrelevant terms as negative keywords to stop wasted spend.
- Product-level performance — pause or adjust bids on products with high spend but zero conversions after a reasonable data window.
- Disapproved products in Merchant Center — a growing disapproval count often signals a systemic feed issue worth fixing at the source rather than product by product.
- Impression share lost due to budget — if this is consistently high on your best-converting products, that’s a signal your budget is capping performance, not your targeting.
Frequently Asked Questions
Do I need a website to run Google Shopping Ads?
Yes. Google Merchant Center requires a working e-commerce website (or at minimum, product pages with pricing and a way to purchase) because Shopping ads link directly to your product pages. A social-media-only storefront or a WhatsApp catalogue alone will not qualify for standard Shopping campaigns.
How much does this Google Shopping Ads setup guide say a beginner should budget?
As general guidance, small Indian retailers typically start testing with INR 300-800 per day (roughly INR 9,000-24,000 per month) to gather enough click and conversion data across a modest product catalogue. Very small catalogues (under 50 products) can often start lower, around INR 200-400 per day, and scale up once specific products show a strong return.
Why did Google Merchant Center reject my product feed?
The most common reasons are missing or mismatched GTIN/brand fields, prices in the feed that don’t match the live price on your website, low-resolution or watermarked images, and misuse of promotional text (like “free shipping” or “50% off”) inside the product title itself, which violates Google’s editorial policies.
What is the difference between Standard Shopping and Performance Max Shopping campaigns?
Standard Shopping campaigns give you manual control over bids and let you see search-term-level data, which is useful while you’re learning. Performance Max automates bidding and placement across Search, Display, YouTube, Gmail, and Maps using machine learning, generally producing better results at scale but with less granular visibility — most beginners start with Standard Shopping for a few weeks before testing Performance Max.
How long does it take for a new Merchant Center account to get approved?
Typically 3-5 business days for initial account and website approval, though feed-level product disapprovals can happen at any time afterward if individual products violate policy. Building in a buffer of at least a week before your planned campaign launch date is sound practice.
