My web team at work has been designing a lot of user input form for websites lately. When creating a Contact Us, Registration, Payment, or really any kind of form, there’s a natural inclination to try and capture as much information as possible. The user is typing data in, so why not ask them for their address, phone #, email address? You could take this opportunity to have them confirm their parish membership data as well. The challenge with this has to do with drop-outs or as online marketers call it, the conversion rate. The conversion rate is the percent of time people actually fill out the form and how many people start, but then stop for whatever reason.
I stumbled across this interesting Infographic that shows the increase in conversion rate (form completion) as the number of fields on a form decrease. The complete Infographic can be found here. Note, the author, Neil Patel, of the Infographic’s site will ask you to sign up for his blog to see the whole thing. If you’re interested in good form design, its worth it.
