The Inquiry Path on Your Website: Contact Form, Callback, Booking
A visitor who has scrolled to the contact section wants something from you. Whether it becomes an inquiry depends on the path you offer and what happens afterwards.
Key takeaways
- There are three inquiry paths: form, callback and appointment booking. Each suits a different situation of the visitor.
- Every field is a small hurdle. Five fields at most remains the rule, but a second, optional stage can help sales without costing inquiries.
- Small commitments make larger ones easier. This principle explains why multi-step forms can work even though they require more clicks.
- The inquiry path does not end with submitting. A clear promise of who gets back when, and a deadline that is kept, are part of it.
Why do so many inquiries get lost in the last few steps?
In the worked example from the article A website that generates inquiries, 120 of 2,000 visitors open the contact page, 60 start the form and 24 submit it. So in the last few steps, half of those who already started are lost, and before that half of those who reached the contact page. These visitors wanted something. The path did not let them through.
The question this article sets out to answer: Which inquiry path suits which visitor, and how do you design the form, callback and appointment booking so that as few people as possible drop out in the last step? To answer it, we first clarify the terms and a principle from social psychology. Then we weigh two views on form length and compare the three paths. At the end comes what has to happen after submitting.
- Contact page opened
- Form started50% of previous stage
- Inquiry submitted40% of previous stage
Worked example with freely chosen numbers from the article “A website that generates inquiries”. Both drop-off points have their own causes: the choice of paths and the form itself.
Every field in the form is a question the visitor has to answer before being allowed to talk to you.
Terms and thinking model: friction and the foot in the door
The inquiry path covers everything between a visitor’s decision to get in touch and the business’s reply: the choice of contact channels, the form or booking, the confirmation and the first response. Friction is everything on this path that creates effort or uncertainty: a required field, an unclear error message, the question of what happens to the data, or the uncertainty of whether anyone will reply at all.
A principle described by Jonathan Freedman and Scott Fraser in 1966 helps with design: the foot-in-the-door technique. In their experiments, people agreed to a larger request more readily if they had first agreed to a small one. The usual explanation: whoever has said yes once sees themselves as someone who takes part and continues to act consistently.
Souchet, Mayeur, Courbet and colleagues (2023) tested a digital form of this. In an experiment with 3,356 internet users who came via a Google search or a Facebook ad to the page of a provider of online training, those who had previously given several small active agreements, for example through simple clicks, were more likely to sign up. The result held for both visitor sources.
Short or multi-step: two views on the form
The first view says: as short as possible. It rests on a simple observation: every detail is effort, and visitors are reluctant to give away personal data. In two web experiments with 535 and 27,900 visitors, Dvir and Gafni (2018) found that a shorter landing page with an identical form led to an inquiry considerably more often than a long one. Less content meant more willingness to provide one’s own data. The article Building a landing page describes the study in detail. This leads to the rule found in several articles on this website: five fields at most, with as few required fields as possible.
The second view says: sales needs information to recognize good inquiries quickly, and a multi-step form can collect it without deterring people. It rests on the principle of small commitments. The first stage only asks what it is about, with a few selection buttons. Name and contact channel come only after that.
The two views can be combined, and I consider the combination the better route. The number of required details stays small, five fields at most. The order begins with the request, not with personal data. Additional pre-qualification details are optional or appear on the confirmation page after submitting. One qualification applies: the experiment by Souchet and colleagues concerned signing up for training, not B2B inquiries, and the study by Dvir and Gafni measured page length, not the number of fields.
By habit
- Salutation, first name, last name, company, street, town, phone, email, message
- All fields required
- Personal data first
- Button: “Submit”
- Afterwards: “Thank you for your message”
By principle
- First: What is it about? Three to four selection buttons
- Then: name, email or phone, short message
- One or two optional pre-qualification fields
- Button: “Request a reply”
- Afterwards: who gets back by when and what happens then
Form, callback, booking: which path fits when?
Not every visitor wants the same thing. Someone with a short question wants to write. Someone with an urgent problem wants to talk. Someone who already knows they want a conversation wants an appointment. Anders, Coleman and Castleberry (2020) found among 160 surveyed buyers in the United States that they preferred email for exchanging information, but the phone for getting acquainted and for difficult questions. Applied to the website, this means the path should match the kind of request.
| Path | Fits when | Advantage | Risk |
|---|---|---|---|
| Contact form | The request needs explaining or the visitor wants to send documents | Structured details, possible at any time | The reply comes too late or not at all |
| Callback request | The request is urgent or the visitor prefers talking to writing | Little effort for the visitor | The callback reaches nobody if no time slot is agreed |
| Appointment booking | A first conversation is the usual next step | Binding, no back and forth | Calendar kept too full or too empty, appointments without pre-qualification |
For most small businesses, one main path and one secondary path are enough. The main path is the one that fits the usual next step in the sale, for services that need explaining often appointment booking or the form. The secondary path is the visible phone number. More than two equal paths confuse rather than help. Whether a chatbot or live chat adds anything is compared in the article Chatbot, callback form or live chat.
How do you design a form that gets filled in?
The following list summarizes what follows from the principle of small commitments and the five-field rule. Go through it with your own form on a smartphone.
- The first question concerns the request and can be answered with one click.
- Five fields at most, of which only name, one contact channel and the request are required.
- Fields have labels, not just gray placeholder text that disappears while typing.
- Error messages say what to do and sit directly next to the field.
- On smartphones, the number pad opens for phone numbers.
- The button names what happens, for example “Request a reply”.
- A short note explains what the data is used for, with a link to the privacy policy.
- Spam protection does not require the visitor to solve a puzzle if it can be avoided.
A note on data protection, without any claim to be legal advice: under European rules, processing an inquiry the visitor makes themselves usually does not require separate consent, but it does require understandable information about what happens to the data. Anyone who also wants to use the data for a newsletter needs separate consent for that. The details are described in the article Data protection in sales. Have your form checked by your data protection officer.
Setting up callback and appointment booking properly
Callback and appointment booking have fewer fields than a form, but their own pitfalls. With both, the risk lies not on the website but in the business behind it.
Offer time slots
With a callback request, the visitor chooses a time slot, such as morning or afternoon. This increases the chance that the callback reaches someone.
State the length and content of the appointment
With appointment booking, the page says in advance how long the conversation is, whether it takes place by phone or video and what happens afterwards.
Ask one pre-qualification question
A single question when booking, such as the request or company size, helps with preparation and costs hardly any bookings.
Keep the calendar honest
Only release times that will actually be kept. A canceled first appointment looks worse than a later one.
Send confirmation and reminder
A confirmation immediately, a reminder the day before. Both with the option to reschedule.
How the subsequent conversation should be structured so that the booking leads to a next step is described in the article The first sales conversation.
What has to happen after submitting
For the visitor, the inquiry path does not end with the click but with the first reply. Oldroyd, McElheran and Elkington (2011) report in Harvard Business Review on a study according to which U.S. companies took an average of 42 hours to respond to an online inquiry, and 24 percent did not reply within 24 hours. The article Lead handover from marketing to sales puts these numbers in context and recommends a deadline the team keeps on every normal working day.
For the website, this leads to a promise on the confirmation page: who will get in touch, by when and through which channel. This promise is only as good as the organization behind it. Every inquiry needs a recipient with a deputy, a deadline and a list in which it lands with source and date. A confirmation page is also the right place for the optional additional questions, because whoever has already submitted can no longer drop out.
How do you measure whether the inquiry path is improving?
The inquiry path is measured at the two drop-off points from the worked example: from the contact page to the started form, and from the started to the submitted form. Many analytics tools show the start of a form as an event if it has been set up. Add the response time, which only your own inquiry list shows.
Worked example with freely chosen numbers. The first row corresponds to the 24 of 60 started forms from the funnel. Change only one thing at a time and compare periods of equal length.
How to calculate and improve the overall inquiry rate is described in the article Measuring the website inquiry rate.
Conclusion and what you can do this week
The opening question was inquiry path suits which visitor and how it must be designed. The answer: one main path that fits the usual next step in the sale, and the phone number as a secondary path. The form starts with the request, stays at five fields at most and says after submitting who will get back by when. Callback and booking need time slots and an honestly kept calendar. In the end, the effect depends not on the website but on the deadline kept behind it.
- Fill in your own form on a smartphone and note every hurdle.
- Reduce required fields to name, one contact channel and the request.
- Put a first question about the request with selection buttons at the beginning.
- Make the button text concrete.
- State on the confirmation page who will get back by when.
- Set recipient, deputy and deadline for inquiries.
- Set up the start of the form as an event in analytics.
A form is not an administrative act but the beginning of a conversation. It should feel like one.
Frequently asked questions
How many fields should a contact form have?
As a rule of thumb, five at most, with as few required fields as possible. Name, one contact channel and the request are almost always enough. Additional pre-qualification details are optional or appear on the confirmation page.
Is a multi-step form better than a single-step one?
It can help if the first stage is easy, such as selecting the request with one click. According to research, small commitments make larger ones easier. The number of required details should still stay small.
Callback request or contact form: which is better?
That depends on the request. For urgent requests or ones that are hard to describe, a callback request with a time slot fits; for requests with documents, the form. Offer one main path and the phone number as a secondary path.
Is online appointment booking worth it for small businesses?
Yes, if a first conversation is the usual next step and the calendar is kept honestly. State the length, format and process of the appointment and ask one pre-qualification question. Send a confirmation and a reminder.
Do I need a consent checkbox in the contact form?
Under European rules, processing an inquiry usually does not require separate consent, but it does require understandable privacy information. For a newsletter, you need separate consent. This is not legal advice; have the form checked.
