# Price benchmark data

Price Benchmark Data shows how your product price compares to the market average for the same product in Google Shopping Ads.

* The benchmark is a **click-weighted average price** calculated by Google across advertisers selling the same item. This means prices from ads that receive more clicks have a greater impact on the benchmark.
* With [Channable CSS Standard](https://app.gitbook.com/s/8y3q10FnokmlpzYq3YPS/manage-your-subscription/channables-pricing-plans/css-pricing), this data is available at product level and can be used for detailed analysis and campaign optimization.

#### Where does the data come from?

The data comes directly from Google Merchant Center, specifically from the [**Pricing** tab in Merchant Center Analytics](https://support.google.com/merchants/answer/13798101?hl=en). Google calculates the benchmark based on real Shopping Ads activity, using prices submitted in active auctions and the actual price shown in the ad when a user clicks.

To compare the same products across advertisers, Google matches listings primarily using the GTIN (Global Trade Item Number). If a GTIN is not available, Google uses a combination of Brand and MPN (Manufacturer Part Number) to identify the product.

#### Benchmark classifications

In the **Product** tab, at the ‘Price Benchmark’ column, each item is classified based on how your price compares to the market average in Google Shopping Ads:

* **Below benchmark:** Your price is lower than the market average
* **At benchmark:** Your price is within approximately ±1% of the benchmark
* **Above benchmark:** Your price is higher than the market average
* **No benchmark:** Not enough reliable data to calculate a benchmark. A product may show **No benchmark** because:
* there aren’t enough other advertisers selling the same item, if important identifiers like GTIN (or Brand and MPN) are missing so Google can’t properly match the product 

or 

* there isn’t enough auction or click data to calculate a reliable market average.
