Question

Search Engine Optimization

Hello! Please tell me what is the best way to name the file name and the ALT attribute when uploading to the online store?
I will give 2 examples:
1- Chanel espadrilles (for all types of shoes that go into the type of espadrille or else)
2- Chanel XXX2482DH2 espadrilles (<<the article that is assigned to this product)
chanel XXX2482DH2 -1
chanel XXX2482DH2 -2 and so on until it ends picture of this product.
How will it be better for Seo and for robots? Thank you all in advance.
