In today’s digital age, websites are crucial for any business and organization. As per siteefy, 252k websites are created every day, and 200+ million active websites right now.It shows how competitive this digital market is. And distinguishing your website between them is challenging.
There are several things to think about when developing a website. There are numerous considerations, ranging from the general appearance and feel of the site to the user experience and functionality. Nevertheless, even the most experienced web designers occasionally commit simple errors that reduce a website’s efficacy.
In this blog, we’ll look at the 23 most common web design mistakes professionals should take care of.
Before we cover these common web design mistakes in detail, it is crucial to understand what web design is all about. Web design is a process of iteratively strategizing, conceptualizing, and delivering information and overall business functionality in an aesthetically appealing layout.
Visual components of web design encompass the text content, images, videos, colors, fonts, different elements and shapes like buttons, forms, and icons, the spacing between these elements, and the overall layout itself.
Design functionality comprises website speed, navigation, animation, user experience, user interaction, overall site’s tech architecture, SEO, cross-browser, cross-platform, cross-device design consistency, and responsiveness.
Here are some of the many benefits of web design to organizations:
Also, it’s important to consider the best web design trends while building them.
Now that we’ve covered web design and why it’s so important, it’s time to understand the common web design mistakes designers and developers must avoid in 2023.
There are many web design mistakes that can negatively impact a website’s user experience, potentially leading to decreased traffic and lost revenue. The common mistakes that need to be avoided are slow page load time, poor mobile responsiveness, unclear navigation, overloaded content, no clear CTA, and other multimedia-related issues, etc. Therefore, it is essential to ensure a positive user experience and maximize the effectiveness of a website. Hence, avoiding these and other common web design mistakes becomes crucial by prioritizing usability principles over flashy features.
When website navigation is not able to give the expected result to the users, the search could be a savior. Those website searches which can’t handle typos, plural, hyphens, or another variant of query terms give unsatisfactory user experience.
Some of the negative impacts of bad searches include
Not all websites require search; however, major websites make these web design mistakes in search, which hamper the user experience. However, it can get resolved by improving the search algorithm and continuously testing the website’s search functionality. Additionally, you can add auto-complete and suggest options in the search bar so users can get fast and accurate results.
According to one report published by WHO, around 1.6 billion people live with special abilities, which is 16% of the world population. But most designers overlook this aspect while designing websites and user journeys. There are millions of people with different kinds of special abilities, and not taking these users in your design-thinking approach could be one of the major yet common website design mistakes. Here is an example of intuitive website design:

Text size, color contrasts, page titles, image alternate text, keyboard accessibility, moving and blinking contents like carousels, ads, auto-playing videos, scrolling news feeds, and tickers are crucial components of a website from the accessibility point of view.
A person with hypermetropia might want to zoom the content on small devices. A person with visual impairment may prefer speech to consume content rather than text. A user with an attention deficit may want to pause carousels and so on. A good web design takes all this into the picture to enhance website accessibility. Doing it wrong can lead to a bad user experience and hurt your business.
Though website security is much of a technical architecture-dependent aspect to an extent, it is also related to website design and user journeys. How designers depict the user journeys greatly influences how developers implement the designs. If website security is prioritized right from the design stage, many web design mistakes related to security can be avoided. For example, putting business-critical data behind authentication and payment walls.
Here are some common web design mistakes related to website security.
The design must be responsive and consistent across browsers and devices to offer an omnichannel experience. One of the big web design mistakes in website development is designing different user journeys and roadmaps for different platforms and devices. The priority should be to maintain as much consistency across devices as possible.
Some of the negative impacts of non-responsive design could be
One of the most common website mistakes to avoid is poor responsiveness. It would be preferable if you could test the responsiveness before going live. Web design tools like LT Browser 2.0, makes it simple to create responsive websites.
One of the most common web design mistakes that most designers make is that they don’t realize the importance of design thinking and drawing the layout on paper. Designers often tend to “assume things” about users rather than do extensive “user research” to understand user needs. But this is not the right way to go about web design.
The design thinking approach is a process that understands and identifies customer needs and motivations. It’s a mindset to empathize with the customers, detail their problems, and build solutions.
Remember – If you don’t understand your customers, you won’t be able to design good websites for them. So, be empathetic, and do user research to understand what your customers care about.
Using CSS tricks and techniques, designers can deliver a seamless user experience where content gets automatically segmented and aligned using rows and columns. Grid-template-columns, min-max, and autofit properties of CSS eliminate the need to use media query breakpoints, but using grid-template-areas does need to use breakpoints.
One CSS Grid-related web design mistake most designers tend to make is getting confused with CSS numbers. While designing for CSS frameworks like bootstrap, we count the number of columns in a row, usually 12, but in the grid system, we count lines or stacks. In the grid system, moving from lines 1 to 7 is akin to spanning 6 columns.

Having trending web design impacts your business in multiple ways. As per one survey by a TOP Design firm, 50% of enterprises think web design is crucial for the overall business and brand reputation. In the modern era, everyone likes trending things, including modern web designs.
Here are some common web design mistakes related to trendy web templates:
Those are some common web design mistakes designers should remember during web development. If you are looking for trending web design templates, read our blog to update your website according to current trends.
SEO-specific and common website design mistakes include not using title & heading tags. Using descriptive page text won’t be as impactful as describing it in the title. Similarly, using larger fonts won’t be as impactful for SEO as using H1 and H2 tags.
Here are some common web design mistakes for SEO every web designer should avoid:
Inappropriate color scheme is one of the most underrated web design mistakes. Color schemes influence the emotions, attitudes, and behavior of the visitors. If you want to create a great first impression for your website, using the appropriate colors is crucial. Contrarily, employing colors that don’t compliment your message can backfire.

Here are some web design mistakes to avoid while choosing color schemes for your websites:
Another web design mistake that most designers must avoid is not strategizing the visual hierarchy of content, including CTAs. Well-devised user journeys can be efficiently implemented by designing efficient visual hierarchies. This can be achieved using appealing words, colors, images, and small animations. Spacing between these elements and their size can also be crucial in driving user engagement. Getting this wrong means less user interaction and can hurt your business’s profitability.
Too little information and you risk not delivering the solution your user wants. Too much information and you may build a solution that is hard to understand, consume, or access. In their sheer desperation, designers can overwhelm the visitors with resources and deliver a highly cluttered website. Though successful, it has been highly popular since the early days. And maybe to maintain consistency for its users, they still haven’t changed the website design. But one should not make the same mistake.
Here are a few tips for organizing content on your website:

Not having a clear CTA is another common web design mistake. Websites are like marketing and sales funnel or pipeline. Your website visitor traverses within that funnel from the prospects’ stage to the converted clients’ stage. Not giving a clear “call to action” at the appropriate places may lead to not converting many hot prospects. Overdoing CTA may also lead to irritating prospects. You can learn the 18 most effective CTA design tips to boost your website’s conversion rate.

We all know that images and graphics are a critical part of web design. When done well, images can clearly convey the message to the visitor. Done wrong, they can confuse the reader. Many businesses are still not paying attention to their images and are using low-quality and irrelevant images.
Don’t make this mistake, as low-quality images will muck up your website and turn off your visitors, hurting your conversions. Similarly, irrelevant images will only confuse your visitors, inducing them not to take the desired action. That being said, you should also not clutter your website with too many images, as they can take away the eyes from CTA, leading to a loss in conversions.
Web design is not limited to developing layouts and user journeys. Wikipedia’s definition expands web design to incorporate content and SEO. From the SEO point-of-view, multiple common website design mistakes can be easily avoided.
The first SEO-critical web design mistake does not have a dedicated custom 404-page template. You can have a custom 404 page for your domain to present users with something relevant, or you may use 302 or 301 redirects to link to some other page on the web. Broken links on a website harm a business’s reputation. Users feel as if the website is a scam and the product/service won’t be of standard. Using 302 or 301 redirects, these broken links could be easily handled. For an external website with broken links, you must continuously test, identify, and replace such links.
Today, it is possible to build websites in multiple languages and even add voice interface-based functionalities. But underestimating this capability as designers could lead to many major web design mistakes. If a business has customers in different countries, then to appeal better to target customers, websites can be developed in the native language.
To boost accessibility, a voice-based interface can be added to the website. A big chunk of google searches on phones is voice-based. Users are using voice technology to book cabs, hotels, etc. It would be a mistake not to count the voice and multilingual approach in the overall website design plan.
Considering the customers from different countries, you might be interested in performing Geolocation testing to ensure a consistent web experience across different geographies.
The design, like content, is a creative work that can be improved iteratively. Using sophisticated analytics tools, your website analytics administrator can give you data on how users navigate your website. Also, analytics and testing can help you discover broken links. Based on the analytics input, you can discover the user journey’s flaws. You can identify what’s working and needs improvements, which CTAs are getting clicked, and which needs upgrading.
After completing the development phase successfully, keeping in mind all the website design problems and web design mistakes to avoid, we can proceed to the testing phase. Testing a website is an indispensable step as the world is filled with devices that are either different physically or from the inside. Cross browser testing, usability testing, and A/B testing are just a few to name, as different goals demand different testing types.
One of the most common website design mistakes that developers tend to commit is assuming that a redesigned website is perfect and not performing browser compatibility testing as rigorously as they should. They feel that since the redesigned website has similar functionalities to the previous one, rigorous rechecking of functionalities is meaningless.
This, albeit, is not a good approach and is an unforgivable blunder in the redesigning part. With this mentality, many things, such as cross browser compatibility, can go wrong.
Therefore, always test your website with an equal commitment to optimize and make it bug-free for your audiences, avoiding all related website design problems.

Page loading speed is a crucial metric for web design. Google also made it one of the key factors for SEO ranking. As per Neil Patel’s blog survey, 53% of users expected websites to get loaded in 3 seconds. Regardless of the device, browser, and operating system combinations used to view a website, it must be optimized for maximum speed.
Here are some common web design mistakes related to page loading that should be avoided:
Another common web design mistake is inefficient features. No matter how visually stunning a feature may be, keep in mind that the effectiveness of your website should always come first. Some common inefficient features include
Because those inefficient features, such as large images and videos, directly impact page load speed and increase bounce rate. And because of the slow loading speed website’s SEO ranking is also getting hampered. All and all, Those features have a compounding effect, and they affect websites’ performance and user experience negatively.
Pop-ups in the right place can be a great lead generation source. However, too many pop-ups can ruin the user experience because users need to close it every time while they are taking some crucial actions on web pages. Also, it clutters the website and makes navigation complicated.
Here are some common drawbacks of irrelevant pop-ups:
To resolve web design mistakes related to pop-ups, you can use analytics, A/B testing, and User feedback to know which pop-ups are most effective. And adding clear and concise messages in pop-ups will save users time, and they will respond faster.
Before even starting web development, if you draft a clear business purpose and mission of the organization, 90% of web design mistakes will not even come into the picture at all. Are you developing an online store where customers may buy products from your business? Or does your website primarily serve to inform visitors about the services your team offers? Once you make sure about the business purpose, it makes you clear about web design, template, copy, content and required features you should include.
A clear business purpose has many advantages:
You can build a strong business purpose by identifying your mission and doing market research, which will help you see through from users’ perspectives and pain points.
A website could be your business’s most important asset, so you must make it flawless to create a great first impression. But to do that, you need to avoid these web design mistakes. Numerous common mistakes can impair your website’s usability, performance, and overall effectiveness, ranging from selecting the incorrect color scheme to overusing animations and effects.

But now that you know these mistakes, you can easily avoid or fix them moving forward and create a user-friendly, aesthetically pleasing, and functional website.
