7 Fatal Errors That Drive Away Visitors on Your Contact Forms

Your contact form is the gateway to your business. Yet, according to a Formstack study, 81% of users abandon a form after starting to fill it out. The culprit? Design errors that seem trivial but cost thousands of euros in lost leads.

You invest in SEO, advertising, content. You attract qualified traffic. Then, at the crucial moment of conversion, your contact form drives away your visitors. It’s frustrating. And above all, it’s avoidable.

Here are the 7 most common errors and how to fix them immediately.

Error #1: Asking for Too Much Information

This is the most widespread error. You want to know everything about your prospects from the first contact: first name, last name, email, phone, company, position, industry, budget, project timeline…

The problem: each additional field reduces your conversion rate by 4 to 7%.

What the Numbers Say

• A 3-field form converts at an average of 25%
• A 6-field form drops to 15%
• Beyond 10 fields, the rate falls below 5%

The Solution

Ask only for what you really need to qualify the lead:

• Name
• Email
• Message (optional)

You can always get more information in the next exchange. The form’s goal isn’t to know everything, but to start the conversation.

Error #2: A Design That Doesn’t Reassure

Your form looks like an administrative questionnaire from the 2000s. No visual branding, fields aligned without logic, confusing labels.

Visitors judge your company’s credibility in less than 3 seconds. A poorly designed form sends a negative signal: “This company is not professional.”

Elements That Drive Away Visitors

• Colors inconsistent with your brand guidelines
• Illegible typography
• Fields that are too small or poorly spaced
• No visual hierarchy

How to Fix It

• Use your color palette
• Allow generous spacing between fields (minimum 20px)
• Choose a readable font at minimum 16px size
• Add your logo at the top of the form

With Skedox, you create forms that integrate perfectly with your visual identity, without touching a line of code.

Error #3: No Instant Feedback

Your visitor fills out the form, clicks “Submit”… and nothing. No confirmation message. No indication that something happened.

Result: they doubt. They click multiple times. They leave. Or worse, they think it didn’t work and give up.

What Your Visitors Expect

• Real-time field validation
• A clear error message if something is wrong
• A visible confirmation after submission
• An automatic confirmation email

Best Practices

• Display a green checkmark when a field is correctly filled
• Indicate the specific error (not just “invalid field”)
• Show a personalized thank you message
• Send an acknowledgment email

Error #4: Ignoring the Mobile Experience

In 2025, over 60% of web traffic comes from smartphones. Yet many forms remain optimized only for desktop.

Common Mobile Problems

• Fields too small to click
• Wrong keyboard (text instead of numeric for phone)
• Submit button off-screen
• Excessive loading time

How to Optimize for Mobile

• Test your form on multiple devices
• Use the appropriate field type (email, tel, number)
• Allow click areas of at least 44x44 pixels
• Place the submit button clearly visible

Error #5: Spam Polluting Your Contact Form Submissions

You receive 50 submissions per day. 45 are spam. You spend hours sorting, miss real leads, and lose confidence in your form.

The obvious solution seems to be CAPTCHA. But beware: an overly aggressive CAPTCHA drives away up to 12% of legitimate visitors.

Finding the Balance

Modern anti-spam solutions work in the background:

• Behavior analysis (filling time, mouse movement)
• Honeypot fields invisible to humans
• AI-based intelligent filtering

At Skedox, our built-in anti-spam protection blocks 95% of bots without impacting user experience.

Error #6: A CTA That Doesn’t Inspire Action

“Send.” “Submit.” “Submit.”

These buttons are functional. They’re not engaging.

Why the CTA Matters

The submit button is the last element your visitor sees before converting. It’s your last chance to convince them.

Examples That Convert

• “Get your free quote”
• “Let’s talk about your project”
• “Get a response within 24h”
• “Start now”

Rules for a Good CTA

• Action verb at the beginning
• Clear benefit for the user
• Color that contrasts with the rest of the form
• Sufficient size (minimum 200px wide)

Error #7: Not Tracking Your Contact Forms’ Performance

You have a form. It receives submissions. You don’t know how many visitors saw it, how many started filling it out, how many abandoned, or at which field.

Without data, you can’t optimize.

Essential Metrics

• View rate: how many visitors see the form
• Start rate: how many begin filling it out
• Abandonment rate: how many leave midway
• Conversion rate: how many complete it
• Average filling time: friction indicator

How to Improve Without Data

You can’t. It’s like driving blindfolded.

With a tool like Skedox, you access a complete dashboard that shows you exactly where your visitors drop off. You can then make decisions based on facts, not assumptions.
