It would be great if there was a Booking Form Element that was titled How Did You Hear About Us? and had a list of multiple choice options including all the major social media/search platforms like Google, Facebook, Yelp, etc. It would also work well with another option for other and then a small text box to go along with it in explanation of the source like a referral, direct mail, another search engine etc. I would like to make this element a required field to be filled out as this will help me to pinpoint the source of the booking lead and adjust my advertising accordingly. I think this will be a tremendous benefit not only for my business, but for all other business that would choose to use this useful element on their booking form.
