Bookshop's affiliate pages look like this. They include a biography section where you can tell people about your store, list your contact info, link back to your primary website, and feature your social media accounts. On your store's Bookshop page, your staff can curate book lists of your store's bestsellers, staff picks, favorite books, etc.
Bookstore affiliates receive 25% of the list price of the books they sell.
