Google Shopping Campaign Setup Guide: Make Your Products Visible

The Google Shopping campaign setup process opens the door to one of the most effective advertising channels available to e-commerce businesses. When users search, your products appear in a visual card format — complete with price, store name, and product image. This format delivers a higher click-through rate (CTR) compared to text ads and makes it easier to reach users with strong purchase intent.

⠀

What Is Google Shopping and How Does It Work?

⠀

Google Shopping is a campaign type within the Google Ads platform. What sets it apart from traditional search ads is this: instead of a keyword list, it is powered by product data (a feed). Google analyzes product titles, descriptions, prices, and images to automatically determine which searches to match against.

Google Merchant Center (the product data hub) and its connection to your Google Ads account form the foundation of this system. The product feed uploaded to Merchant Center is the raw material for Shopping campaigns. The more accurate and complete the feed, the more precisely your ads are shown for relevant searches.

When a user searches for "red running shoes," Google scans your catalog and presents the most relevant products as visual cards. At this point, the quality of your Google Shopping campaign setup is the primary factor in getting ahead of the competition.

⠀

Prerequisites Before Google Shopping Campaign Setup

⠀

Before moving on to the Google Shopping campaign setup process, the following requirements must be in place:

• Google Merchant Center account opened and store information added

• Website verification completed (domain linked to Merchant Center)

• SSL certificate active — sites without HTTPS are not approved

• Return policy and privacy policy pages present on the site

• Google Ads account linked to Merchant Center

⠀

If you have not already completed the Google Merchant Center setup, you must complete that step first. It is not possible to set up a Shopping campaign without Merchant Center.

⠀

Preparing the Product Feed

⠀

The feed directly determines the quality of Shopping campaigns. The more complete the product data uploaded to Merchant Center, the more precisely ads match relevant searches.

Required feed fields are:

1. id — Unique identifier for each product

2. title — Product title (the most critical field — the part that matches search queries)

3. description — Product description

4. link — Product page URL

5. image_link — Main product image URL

6. price — Price and currency (e.g., 29.99 USD)

7. availability — Stock status (in_stock / out_of_stock)

8. brand — Brand name

9. gtin or mpn — Product identifier code (if available)

⠀

Title optimization is critically important. Detailed titles like "Nike Air Max 270 Men's Running Shoe Red" instead of just "Shoe" ensure your products are shown for more precise searches.

⠀

Google Shopping Campaign Setup Steps

⠀

Once your Merchant Center account is ready and the feed is uploaded, you can move to Google Ads.

Step 1 — Create a Campaign: In Google Ads, select "New campaign." For the goal, you can choose "Sales" or "Website traffic." Set the campaign type to "Shopping."

Step 2 — Merchant Center Connection: Select your linked Merchant Center account on the next screen. Specify the country you sell to.

Step 3 — Choose Campaign Subtype: The "Standard Shopping" option gives you control at the product group level. A Performance Max campaign automatically optimizes across all Google channels but gives you less control.

Step 4 — Bidding Strategy: For starters, choose "Maximum Cost Per Click (Manual CPC)." Once sufficient conversion data has been collected, you can switch to smart bidding strategies such as Target ROAS (tROAS).

Step 5 — Budget: Set your daily budget. For new campaigns, it is reasonable to start with a lower budget during the testing phase.

Step 6 — Product Groups: You can manage all products in one group, or split them into subgroups by attributes such as category, brand, or product type. Different bids can be assigned to different product groups.

⠀

Using Negative Keywords

⠀

Even though Shopping campaigns do not use a keyword list, you can still add negative keywords. This prevents your ads from showing on irrelevant searches and eliminates wasted budget.

For example, if you sell shoes, adding terms like "free," "how to make," and "second hand" as negatives filters out clicks with low conversion potential.

We covered negative keyword management in more detail in our guide on Google Ads account structure.

⠀

Measuring Campaign Performance

⠀

After the campaign goes live, the most important step is tracking the right metrics.

Core metrics to monitor:

• ROAS (Return on Ad Spend): Revenue generated per dollar spent on ads

• CTR (Click-Through Rate): Percentage of clicks per impression

• CPC (Cost Per Click): Average cost per click

• Conversion Rate: The percentage of clickers who make a purchase

• Impression Share: How visible you are compared to your competitors

⠀

You must set up conversion tracking via Google Ads or through GA4 integration. It is not possible to optimize a Shopping campaign without conversion data.

⠀

Common Mistakes

⠀

Neglecting feed quality: Incomplete or incorrect product data leads to ads being disapproved or shown for irrelevant searches. Check your feed regularly.

Keeping all products in one group: Assigning the same bid to products with different margins and sales velocities leads to poor performance. Split product groups and adjust bids accordingly.

Ignoring image quality: Clean, high-resolution product images on a white background directly affect CTR. Low-quality images also cause issues during the approval process.

Overlooking mobile performance: A large share of shopping searches come from mobile devices. Monitor mobile bid adjustments and landing page performance separately.

Frequently Asked Questions

⠀

What is the minimum budget for a Google Shopping campaign?

There is no fixed minimum, but starting with at least $10–20 per day is recommended to collect meaningful data. If the budget is too low, the campaign will not get enough impressions and no optimization opportunity will arise.

How do I link Merchant Center to Google Ads?

In the Merchant Center panel, go to "Tools > Linked accounts." Under the "Google Ads" tab, enter your account ID and send a link request. Approve the request on the Google Ads side.

My Shopping campaign isn't getting approved — what should I do?

Check the "Products" tab in Merchant Center to review the reasons for disapproved products. The most common issues are: missing price information, mismatched URLs, HTTPS problems on the site, or the absence of a return policy page.

Should I choose Standard Shopping or Performance Max?

Standard Shopping gives beginners more control. After accumulating a certain conversion history, switching to Performance Max can provide the advantage of reaching a broader audience.
