8 Common Web Usability Mistakes and Best Practices

This article discusses common mistakes in web programming that affect website usability and provides corresponding solutions to help improve user experience.

Mistake 1: Form labels not associated with corresponding fields

Using the "for" attribute allows users to select the correct input field by clicking the label. This is especially important for checkboxes and radio buttons to create larger clickable areas.

Mistake 2: Logo image not linked to homepage

Adding a link to the homepage from the logo is a fundamental practice. Most users naturally expect clicking the logo to return to the homepage. The logo is best placed in the top-left corner.

Mistake 3: Not showing link visited state

Displaying whether a link has been visited is often overlooked. It is important for users to easily see whether a link has been clicked.

Mistake 4: Not showing currently active form fields

You can use "focus" selection or binding elements. The most useful method is to indicate that the field is active using input and textarea elements. This includes CSS styles such as highlighted borders or subtle background color changes.

Mistake 5: Images missing descriptions

Unless used purely for decoration where the ALT attribute can be left blank, descriptive text should be added to images. The benefit is that when images are used as links, the descriptive text allows search engines to access those links.

Mistake 6: Background images without background color

Using background images for certain content is common practice. However, if a user disables background images, the text in that section becomes invisible. It is best to set a background color as well.

Mistake 7: Inconsistent interface design style

Excessive creativity can sometimes be counterproductive. Some designers make the mistake of having different designs for each page within the same website. This is not only confusing but also annoying for users. No matter how stunning a website is, if the overall style is inconsistent, it won't gain user approval. Recommendations: use templates and keep it simple.

Mistake 8: Underlining non-link content

As everyone knows, content with underlines or shadows is likely to be a link. To avoid misleading users, it is best to use bold or other emphasis indicators instead.
