Forms people actually fill in – less friction, more replies

The form is often the last step before a conversion – and the place most people drop off. They've decided, clicked the button, and then they meet a wall of fields.

Every field you ask for costs you a few replies. The question isn't how much you can ask, but how little you need to.

Ask for as little as possible

The most common form mistake is asking for too much. Every extra field is a fresh reason to give up.

Go through the form and ask of each field: do I need this now, or can I ask later? For a first contact form, name and email is often enough, or even just email. The rest can come up in the conversation afterwards.

• Do you really need a phone number and an email on first contact?
• Do you need a company name to reply to an enquiry?
• Do you need "how did you hear about us?" before you've even spoken?

Usually the answer is no. Ask for what you must have to take the next step, not everything you might like to know.

Make it obvious what's expected

People fill in what they understand. A field labelled "Name" is clearer than an empty box with no label. A label above the field is easier to read on mobile than one inside it that disappears once you start typing.

A few simple moves help a lot:

• Visible labels above the fields, not just placeholder text
• The right keyboard on mobile – a number pad for phone, an email keyboard for email
• A logical order that follows how people think
• Clear marking of what's required and what's optional

Error messages that help, not scold

Nothing kills a form faster than a red error message that doesn't say what's wrong. "Invalid input" helps no one.

Show the error next to the field it concerns, and explain what's missing: "The email address is missing the @." Check the field as people fill it in, not only when they press send – that way they avoid discovering five errors at once after they thought they were done.

And most importantly: don't clear the form on an error. Few things are more annoying than having to type everything again because one field was wrong.

One question at a time on long forms

If you have to collect a lot of information – say in an order or an application – it often works better to break it into steps than to show it all at once.

A long page with twenty fields looks overwhelming. The same twenty fields spread over four short steps, with a clear progress indicator, feels manageable. People are more likely to finish something that looks like it's heading towards the end.

Be honest about what happens next

Uncertainty stops people right before they press send. They wonder what happens, whether they'll be spammed, and how long it takes.

Answer that right next to the button:

• "We reply within one working day."
• "No obligation – no salesperson will call."
• "Takes two minutes."

These little lines remove the last hesitation. They cost nothing and bring in replies you'd otherwise lose.

Confirm that it worked

When someone has submitted, they should know it straight away. A clear thank-you message or a short confirmation page closes the loop.

An empty form that just resets itself leaves people unsure whether it actually went through – and some submit again, or worse, give up. Tell them it worked, and ideally what happens now.

A quick test

Want to know if your form is too heavy? Fill it in yourself on a phone, standing up, with only one hand free. If it feels like a chore, it does for your visitors too.

A good form asks for just enough, makes it easy to answer, and tells people they're in safe hands. If you'd like help tidying up a form that's losing replies, we're happy to take a look.
