How to create an online form

Now that you know how to choose a form builder let’s find out the exact steps to take when making an online form.

Create new or use a template 

Obviously, the first step is to create a new form. Most form builders will allow you to modify an existing form template or create one from scratch. 

Add form description to let users know the purpose

You need to define the purpose of your form to your website visitors, and you can do that by including a short heading that describes what the form will do, such as “Contact us” or “Place an Order”. Also, you can use the subheading section to add extra details.


Branding elements can definitely make your form stand out, but there’s no need to dwell on it. You can still make it look simple and concise. You can include branding elements such as the company logo in the header or use your company colors that show off your brand’s personality. You can also use a  specific font for all your forms, so people recognize it’s coming from your business

Add fields

Build your online form by adding as many fields as you need. You’ll most definitely have short and long questions which can require a certain type of field, in a certain order. A form builder should allow you to personalize the display of fields and have no limits on the number of fields you plan to include.

Keep it relevant with conditional logic

Making an online form requires understanding conditional logic, which relies on the “if-then” paradigm. When you create a web form with conditional logic, you keep it relevant by including conditional fields that are either hidden or unfold depending on the responder’s answers.

Include a “Thank you” message or page

Show your appreciation with a creative thank you page or a simple success message. Not sure exactly what to say in your thank you message? We have some ideas for you:

An automatic email responder will add personality to the basic process of thanking a customer. It will also create a bridge of communication with your audience.

Test & publish

All of the previous steps show you how to make online forms so you can start collecting data. 

But before you can do that, you need to test the form to make sure it works on multiple browsers and devices and that all the fields are as intended.

Fill the form out and submit it via your phone and a non-default browser to be sure it works properly. And when you see that everything looks clean, you can finally publish the form.


The answer to the question “How to build an online form?” isn’t complicated at all if you know all the right steps. As long as you know what to look for in a form builder, the purpose of your form, and how to make the form itself, building an online form is a breeze with the right tool.
