Which web elements are complementary and essential for business growth?
Ask about the actual essence of the business that is completely unique from others and will compel visitors to prefer you among others. Instead of making assumptions and integrating features with no business scope, ask your client for the guidance.
If he/she is running a coffee shop, you may need to integrate the menu and have to mention its opening and closing hours. Likewise if he/she has a real estate business, you may have to showcase images and videos of the commercial or residential properties currently available.
Always try to gather all the significant details about website features before proceeding by, as later additions may cost your time and efforts.
