Top 10 Web Design Principles

1) Don't Forget To K.I.S.S. - Keep It Simple, Stupid!

This one is the most effective and popular web design principle. K.I.S.S, also known as Keep It Simple, Stupid is widely recognised as the most valuable principle of all. The phrase itself is easily understood, which says "Simplicity is the key to success". This principle explains to always aim for simplicity and to create easy actions for your audience so that there isn't any confusion.

Also, it's similar to Hick's law, the quality of being simple and uncomplicated in the form of design. A page overloaded with information gives rise to a complex situation and doesn't go well with internet users.

When you keep things straightforward, they become even more visually appealing. Building an excellent user experience also helps you in opting out of anything unnecessary to the web design. 

2) Stick To Hick's Law

Hick’s Law, or the Hick-Hyman Law, is named after a British and an American psychologists team of William Edmund Hick and Ray Hyman. It's a popular theory that is quoted by many individuals for different objectives, but it is mostly referred to as web design. 

Hick's law describes that a person who is loaded with a lot of choices will take a much longer time to conclude. In simple terms, when the number of choices given to a person increases, the time taken to make a decision also increases.

 A popular theory in the field of web design explains why many brands are limiting the content on their navigation bar. This way, it becomes a lot easier for the users to find a definite solution for their specific problem.

3) Obey The 8 Second Rule 

Have you heard yet that the human attention span is even less than 12 seconds? Yes, you read that right! 

Nowadays, people typically lose their concentration power just after eight seconds. That's the reason why it's vital to make those 8 seconds count the moment they visit your website.

There are a lot of things you can do to seize their attention, such as the hero image on your website should be out of the ordinary & extremely attractive, teamed up with a headline that helps describe your products & services in terms of benefits offered to your target customers. You can even use "exit animated pop-ups" to once again engage the visitors who got bored after a certain period. Curate the sign-up/register buttons pretty large so that I will be easily visible to the audience and try to include multimedia content like video, audio or any content that is interactive.

4) Make Use Of High-Quality Images

One thing that could pull down the quality & integrity of your blog or any content on your website is because of low-quality images. Images are truly responsible for causing a positive or negative impact on the users & their actions. Articles with appropriate images receive more than 94% of views when compared to articles without any images. Moreover, 67% of customers confessed that the quality of a product image is “very essential” in choosing and buying the product.

You should try to avoid low-quality, lifeless images in your blog posts or web pages.

You might be thinking that "The Rule of Third" is only limited to photography, but you must be inquisitive to know that it’s undoubtedly one of the fundamental principles of web design. Rule of thirds suggests visually intersecting a page of the website into thirds. Substantially, this will result in leaving you with two equally spaced vertical & horizontal lines, i.e. nine equal square boxes.  

After this, you need to concentrate on the given four sections in the middle because, according to the Rule of Third, this space is the strategic space of attention. You must position the essential elements of the website here, such as features of your products, CTA or a highly influential image. 

6) The Strength Of Colors

Colours play a vital role in expressing a message and give a soothing effect to one's mind. It does affect the perception of the people about your brand, whether it's online or offline.

7) Invest In Optimum Speed

The Internet is one of the reasons why people have become so impatient with time. You would be surprised to know that just a 2-second delay has been successful in contributing to a 103% increase in bounce rates.

Every second counts when it comes to page loading speed, ensuring that you design a website for your business for optimum speed. There are various ways through which you can achieve this criterion, such as performing a compression audit, minimizing HTTP requests, minifying and incorporating files and enabling browser caching. These are a few ways that will help you to increase the speed of your website. 

About this particular web design principle, you should always try to check your website page's speed and whether there are any troubleshooting issues.

8) Utilize Faces To Stretch Familiarity

Humans do connect with other humans, and there's an exchange of positive energy between them. When you follow this principle and incorporate pictures of other people instead of using vector images, people will connect to that. Many studies describe how using images of people increases the conversion rate because users feel more comfortable & connected. 

Nevertheless, always try to drive away from stock images because customers are more likely to trust businesses that are personal and genuine.

9) Gestalt Similarity Principle

Gestalt principles or laws are rules that narrate how the human eye observes visual components. These principles strive to exhibit how complicated events can be lessened to more simple patterns. They also aspire to illustrate how the eyes anticipate the shapes as a single, united form instead of having distinct, simple elements.

The initial Gestalt principle is the law of similarity that confesses that the human eye or brain prefers to group similar objects, and it's a means that enables us to create a sense of things and to regulate a noisy environment.

When it comes to web design principles, you can enforce this law by sorting items into groups that you want to be connected to, for instance - images, testimonial boxes, or conversion buttons.

10) Have Regard To F-Layout 

According to various research that has been carried out in recent years, browsing a web page in an F-pattern is the innate behaviour of internet users. In simple words, people tend to look from the left side of the page to the right side, starting at the topmost part of the screen. As they scroll down the page, they just scrutinize the page.

This means that the part which receives less attention is the bottom-most part of the page. Hence, you should place the essential elements & messages considering the F-layout.
