If you want to make a web form survey for your website design, what are the most important question you will ask?

in the first thank you for your invitation, according to your question you have to divide your survey into at least three sections

first section is about general info about the user because it's important to know the age and gender of the people who will evaluate your website and their familiarity with websites surfing as well

before writing the second section you've decide the things you want to ask about (navigation, links, colours, images, speed of loading, security if there is payment methods) I can give you this link in Shaa Allah it is useful for you. ... your questions should take rating shape and keep one or two question as open questions for more valuable suggestions
