“Contrary to what you may read, peppering your form with nice buttons, color and typography and plenty of jQuery plugins will not make it usable. Indeed, in doing so, you would be addressing (in an unstructured way) only one third of what constitutes form usability”
This is the opening line in a very informative article about form usability – An Extensive Guide To Web Form Usability (Justin Mifsud, November 2011, www.smashingmagazine.com).
In the article the author draws together research and insights from various fields – usability testing, field testing, website tracking, eye tracking, web analytics and actual complaints made to customer support personnel by unhappy users – and leverages this to provide some clear guidelines for developers and solution architects to consider when designing forms.
He highlights the importance of usability on forms and defines the reason for the existence of the form for both the user and the business. The table below outlines that every form exists for one of three main reasons: commerce, community or productivity. The table translates each of these reasons into the user and business objectives that lie behind them.

It is important to consider that forms can make a website usable or unusable, because they can stand in the way of the user achieving their goal or simplify the process for both the business and the user. Hence, forms need to be usable in order to help the user achieve that goal.
Justin tackles usability by addressing three aspects common in all forms. All these areas need to be planned and integrated to achieve a usable and successful form interface.
- Relationship – Forms establish a relationship between the user and the organization.
- Conversation - They establish a dialogue between the user and the organization.
- Appearance – By the way they look, they establish a relationship and a conversation.
The guidelines provided in the article are a good starting point to embark on when designing forms for any website.
Justin’s research methods are similar to the process embarked on by the Conversion Services team at Clickthinking. We also use additional tools to perform detailed form analysis that is customised to specific forms on a website. These tools will indicate exactly where users drop off on forms, which fields are slowing the process down, or if users have difficulty understanding or submitting the form. If you already have a form on your site and you are not sure if it is completely optimised to your user’s needs, then form analysis is recommended.Contact conversion@clickthinking.com for a more information about our services.
