What is Inline Validation?

In the world of web design and marketing, inline validation is a user interface design pattern that, if implemented properly, improves the user experience and increases form conversion rates.

The idea behind inline validation lies in providing instant feedback as users fill forms during registration or sign-up process, saving them from encountering a bulk of errors at the end of the process. As individuals fill out a form, errors or missing fields are quickly highlighted, allowing for immediate correction.

The concept of inline validation has been around for some time, originally popularized by Luke Wroblewski, a renowned product director at Google. Recognizing the critical role that validation plays in increasing overall user satisfaction and engagement, Wroblewski advocated for the use of this tactic to improve the user's experience and simplify forms.

When focusing on conversion, inline validation is a powerful tool as it makes forms more straightforward and efficient, minimizing the likelihood of user drop-offs due to cumbersome or confusing input fields. Inline validation reduces ambiguity and mistakes, leaving users with a smooth, frictionless experience that nudges them closer to conversion and reduces bounce rates.

Examples of Inline Validation

  1. E-Commerce Checkout: When a customer is finalizing their purchase on an e-commerce website, fields like name, address, credit card details etc., could be validated in real time, to ensure seamless checkout experience.

  2. Email Newsletter Signup: While signing up for a newsletter, if the person enters an incorrectly formatted email address, an inline validation message can prompt the correct formatting.

  3. Registration Page: In a registration form for a webinar or an event, inline validation could help prevent any wrong entries on mandatory fields like phone number or ZIP code.

  4. Online Banking: For online bank account creation, inline validation ensures secure password creation by real-time check if the entered password meets the necessary criteria.

  5. Survey Forms: In surveys, if a user tries to proceed without answering mandatory questions, inline validation can guide them to complete missing answers.
