Getting too specific by asking for too much detail can have the reverse effect
, so when you make a website with a landing page that requires some kind of input from the visitor, keep it general and as non-intrusive as possible. A good example might be to only ask their age range rather than exact age or birthday details people are much likely to be more forthcoming and if you can get them to buy something, you can find out all this stuff later. This small amount of information is usually sufficient to be able to direct them towards your website pages. It is up to the website builder to devise a strategy for channeling visitors toward a more likely sale - and understanding demographics is often what makes that possible.
