Google Shopping ads are paid placements; free product listings are unpaid. Both can appear on some of the same Google surfaces, including the Shopping tab, so a product’s location—or a “Product” label—does not by itself tell you whether it is an ad. The practical differences are how each format is enabled, how merchants are charged, and how clicks are measured.
Where ads and free listings can appear
Google says eligible free listings may appear across Search, Maps, Gemini, YouTube, the Shopping tab, Google Images, and Google Lens. They have no placement charge, but eligibility does not guarantee that a product will be displayed: Google matches submitted product information to relevant searches. See Google’s explanation of free listings.
Shopping ads occupy ad slots on the Shopping tab, and Google says they continue to appear there alongside free listings. In markets where the CSS program operates, CSSs can also place Shopping ads on general Google Search results pages. Therefore, seeing a product in the Shopping tab does not establish that it is paid; the surface can contain both formats. Details are in Google’s Shopping tab and CSS guidance.

Look for an explicit advertising designation where one is shown, but do not treat every product-related badge as proof of paid placement. On Google Images, the “Product” label can indicate that the pictured item is purchasable; Google does not define it as a paid-ad badge. Google says annotations and badges may be used on both Shopping ads and free listings, and their display can vary by relevance, device, surface, and country. Its annotations guidance lists possible details such as sale prices, promotions, ratings, shipping speed, and return policy—not guaranteed labels or a universal ad test.

How merchants enable each format
Free product listings
Products must comply with Google’s policies and include information Google can match to relevant searches. Google says free listings are on by default in most cases, but merchants should check their Merchant Center configuration. Enabling the feature makes products eligible; it does not promise impressions, clicks, or sales. Google’s free listings help page describes eligible surfaces and setup.
Shopping ads
Shopping ads require campaign setup in Google Ads. The setup path and any intermediary requirements depend on the market and the merchant’s arrangement; the CSS route described by Google should not be assumed to apply identically everywhere. See Google’s CSS program information.
What each format costs
| Format | Placement charge | Merchant-facing cost |
|---|---|---|
| Free product listings | No placement charge, according to Google. | Google’s documentation establishes no charge for placement; it does not quantify merchants’ own costs for creating and maintaining product data. |
| Shopping ads through a CSS | Auction-based. Google invoices the CSS for ad clicks, with the amount depending on the auction outcome. | The CSS charges the merchant according to its agreement. Documented models include fixed cost per click, category-dependent click fees, commission when an ad click leads to a sale, or a percentage markup on auction CPC. |
Google does not publish one universal Shopping ads click price for merchants. The actual merchant cost depends on auction results and the CSS’s agreement, so a general CPC or return estimate would not be reliable. Google explains the billing relationship and examples in its CSS pricing guidance.

Google lists the following countries where CSSs must be used on a merchant’s behalf to place Shopping ads and free product listings on Google: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Ireland, Italy, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Spain, Sweden, Switzerland, and the United Kingdom. Google says merchants can work with multiple CSSs. Because geographic program requirements may change, check the current country and CSS information for the market you serve.
When evaluating a CSS, compare its service scope, account access, campaign management, reporting, and fee model. Google describes managed-service arrangements in which the CSS controls accounts and self-service arrangements in which the merchant has access; terms and pricing depend on the agreement.

Use Google Ads reporting to track paid clicks and Merchant Center reporting for unpaid clicks. In Merchant Center Analytics, Google categorizes free-listing traffic as Organic. Google Analytics may show Google Ads traffic as google / cpc and free-listing traffic as google / organic; Google recommends checking analytics data against Merchant Center reporting. See Google’s guidance on measuring free-listing performance.
Keep impressions, clicks, spend, and conversions distinct when comparing results: a listing may receive impressions without clicks, while paid spend is not the same measure as conversions. Unpaid placement means Google does not charge for the listing itself; it does not mean product-data work or maintenance has no internal cost.
