8. Provide field hints to help users
Sometimes, it is necessary to prompt the user as to what information a field is asking for, for example, a strong password or a CV2 number.
Field hints can take the form of an inline text placeholder, an annotation, or in some cases, a graphic.
9. Use auto-parsing and formatting
Some fields, such as phone number and credit card, can be auto formatted to help the user check if they have entered the correct information.
For example, you can enter a space or dash after each set of four numbers entered in the credit card number field of your payment form.
10. Make sure you’re tracking form errors
Ultimately, once your checkout is launched, you will wish to analyse its performance, and optimise it appropriately.
It’s important to note that before you can run form analysis tools on your checkout, it must be coded correctly.
