In today’s digital age, a well-designed website is no longer negotiable—it’s a must. Unfortunately, there are some simple mistakes that people make that can really deter visitors and harm online success.
When it comes to web design, it is important to remember that it takes two to tango; those two being form AND function. Designing a good-looking website that works well requires following best practice. So what should be mindful of?
To help you steer clear of some common web design pitfalls, we’ve compiled a list of the top 10 web design mistakes and how to avoid them.
1. Neglecting Mobile Optimisation
One thing you should remember when it comes to web design is MOBILE FIRST. What does that mean exactly? Well, in a B2C environment, the majority of your web traffic is likely coming from mobile devices. That’s why Google indexes the mobile version of your website. For game-changing sales conversions and top search engine rankings, it is vital that your website is responsive and mobile-friendly. Weirdly placed text, buttons that don’t click, or images that are so big they take up the whole screen can mean mobile users don’t get the most out of your site. Your website should be designed with the mobile experience front of mind.
Neglecting mobile optimisation can lead to a poor user experience, losing enquiries and sales. Instead, aim for your website to be fully mobile-responsive and able to adapt to various screen sizes and browsers on multiple IOS and Android devices.
2. Complex Navigation
Complex and confusing navigation menus can frustrate visitors and deter them from finding what they need on your site. This is why we recommend keeping your navigation simple, intuitive, and organised. Use clear labels for menu items and ensure that users can easily find what they’re looking for and avoid burying pages or content too deep in your site. You want customers to find what they’re looking for quickly and easily.
3. Slow Page Loading
A slow-loading website can lead to high bounce rates and reduced search engine rankings. Optimise your site’s speed by compressing images, using effective plugins, minimising unnecessary scripts and conducting regular maintenance across the site. Tools like Google PageSpeed Insights, Yellow Labs Tools and GTMetrix can help identify and address performance issues. If you’re not sure what all of that is, don’t worry. Improving page speed often requires the expertise of a developer, otherwise, you may risk breaking your website.
4. Lack of Clear Calls to Action (CTA)
Every page on your website should have a clear and compelling call to action (CTA). Whether it’s signing up for a newsletter, making a purchase, or contacting your business, a well-placed CTA guides visitors toward a desired action. Make sure your CTAs are noticeable and concise. Great CTAs could be those such as ‘Call Now’, ‘Book your Free Consult’, ‘Order Today’ or ‘Speak to an Expert Now’ etc.
5. Poor Content Structure
You’ve probably heard the cliché ‘content is king’. However, content must be more than just relevant and fresh; it must be presented in an organised and easily digestible manner in order to be effective. Avoid long paragraphs and use headings, bullet points, and white space to break up content. Ensure that your content is informative, relevant, and free of grammatical errors. Once again, as mentioned in point 1, consider how it will look on mobile devices.
6. Inconsistent Branding
If you think about some of the globe’s biggest brands, which ones come to mind? McDonalds? Coca-Cola? Nike? And what do they all have in common? Consistent branding.
Consistency in branding is essential for building trust and recognition. Ensure that your logo, colour scheme, typography, and messaging align with your brand identity across all pages of your website, social media and marketing collateral. Inconsistencies can confuse visitors and erode your brand’s credibility.
7. Overloading with Pop-Ups
How many times have you visited a website only to be bombarded with discount codes, newsletter signups, chatbots and the like? When used in moderation, pop-ups can be effective for lead generation, but excessive or intrusive pop-ups can just as quickly turn visitors away. Use pop-ups sparingly and ensure they are relevant to the content and timing. Offer value in exchange for contact information, such as a discount or valuable content and only one at a time!
8. Ignoring SEO Best Practices
Search engine optimisation (SEO) is vital for improving your website’s visibility in search engine results. Strive to follow SEO best practices, such as optimising meta tags, targeting relevant keywords, creating a strong internal linking structure, and creating high-quality content. There’s a lot that factors into SEO, but focusing on these on-page elements is a great start.
9. Forgetting About Accessibility
Web accessibility is not just a legal requirement; it’s also essential for reaching a broader audience. Ensure that your website is accessible to individuals with disabilities by using proper headings, alt text for images, and keyboard navigation support. using alt image tags correctly will improve your SEO too as Google uses this tag (originally designed for for vision impairment) as a ranking factor for images.
10. Neglecting Analytics
To get the most out of your website, it’s important to monitor your performance. But how? Tools like Google Analytics can monitor user behaviour, traffic sources, and conversion rates so you can make informed decisions, continuously improve your website, and generate quality leads.
