You can use a [Google Shopping Supplemental Feed](https://www.takesomerisk.com/google-shopping-supplemental-feeds/) if you want to change your product titles for shopping ads but not change what is on your site. Also Google looks at your whole shopping feed when deciding what to rank for products and SKUs for. Make sure you have a good product description too.

You can add any words you want to your product title but it’s best to keep it relevant to what you are selling.
