What are the errors of the user interface design ?


In online business, creating trust is much more difficult than in real life because people can’t see your face. All they can judge you for in the first place is how good your website design is. There is thus no doubt that the user interface (UI) is the key to the site success. Visitors to the website place a lot of importance on this. Generally, first they see the UI design, then interact with it regularly. They usually leave a site if they find its content boring or if its layout does not look impressive. When it comes to a professional website, many people think that conversion rate optimization depends mainly on the UI design. And to increase your conversion rate, it is essential to avoid many user interface design errors that can hinder a site’s ability to convert visitors into customers.

Non-responsive design

Non-responsive design is one of the big faults of website user interface design. Many people use mobile devices and laptops to surf the net. When the pages of the site do not display correctly across different platforms and devices, this shows that the site is poorly designed, may even be useless for the majority of Internet users. Most people leave your page, if they cannot view or play the content properly.

If the design is non-responsive, internet users can’t access the best features using the devices of their preference.
A non-responsive design even prevents sites from providing the best user experience.

Wrong Position of Call to Action

Your website has definitely a goal. Whether you want your visitors to sign up for a mailing list, make a purchase, request a quote or just call you, there must be a goal and you must clearly explain to your visitors what your goal is. Call-to-action buttons are an essential part of any website. They direct users to desired results and increase the conversion rate. They drive sales, generate prospects and increase revenue for your company. In many cases, low conversion rates are the direct result of a call to action that gets lost in web design. To increase the conversion rate on your website, you need to appropriately place the call-to-action buttons. Put enough information about what visitors will get taking action and about what information they need to provide.

The call-to-action of a site should always follow the mindset of the users. Their thoughts and their purchasing attitude become effective when deciding on the features mentioned in your call to action.
