Hi,

For SEO, What is the best way to solutions of out of stock product.

Hi there,

There are many ways of handling Out Of Stock products, it essentially depends on how probable is that the product has stock again:
1- Unique item. You can go for: 404 that page, hide it under a login or redirect to a custom out of stock page, so as users can search for anything else.
2- Will have stock soon: Schema is the way to go. This the parameter could be useful: https://schema.org/OutOfStock

It always depends on how you want to handle user experience for people coming from search engines. Some ecommerce just convert them into 404, others redirect it to he category or to a internal search page and other even just set a noindex tag.

Hope it helps.
Best luck.
