In Addition, Google has feeds specifications that need to be accurate and updated for the campaigns to run correctly. Once the feed has been uploaded, Google will process it and prove it; This process can last up to 72 hours, depending on the size of the file. It is important to remember that the products expire after a period of 30 days, when it will be necessary to re-send the feed so that the products will continue showing in the Results Of Google Shopping.

If the price, availability, and bid price of a store change frequently, this information can be updated through the product Inventory Update feed. This feed can be sent on a daily basis or as often as the products change or update. As a general rule, it is important for the customer to click on a website and see the same product information (price, availability, etc.) as presented in the Google Shopping results.

The feed should be carefully monitored to detect warnings and errors and correct them. To See the status of your feed, you can enter Adwords-> Tools-> Google Merchant Center, where you can see the data quality indicators, with the type of signal and the percentage of products affected.
