We all use online persuasion more or less consciously, but knowing some basic principles of web psychology can make all the difference.

Colours

You can’t really discuss colours without referring to colour psychology, which is a branch of behavioral psychology focusing on the effect of colours on human attitudes and behaviours. Colour psychology is extremely useful for online entrepreneurs, as every single detail on a website communicates a message to the customer. By choosing colours for your website, you decide which parts of your website you want the visitors to see first, which is a huge choice to make.

Colour equals emotion

Colours evoke fairly universal associations, they also correspond to various emotions. This correlation is depicted on Robert Plutchik’s Wheel of Emotions. Notice how tints and hues change the intensity of a given emotional state.

As an example, yellow can be associated with happiness and joy, which are one of main triggering emotions for sharing. Do your research when it comes to cultural differences regarding how colours are perceived in other countries. As an example, red is associated with love, lust, speed in Europe, but in Asian countries it symbolizes luck, prosperity, and marriage.

Colour vs identity

Some companies go as far as building their brand identity based on a particular colour. They aim at instant recognition based on colour cue itself. Here’s a great example - close your eyes and think of Cadbury’s chocolate bar. The first thing you’ll probably think of is their purple chocolate wrapper. And here’s a fun fact - Cadbury colour trademarked purple for chocolate products.

Colour is one of the first things you see when you open a website, so chose wisely. Colours are powerful means of communication as they evoke certain associations and emotions - as an example, purple or pink are often used in the cosmetics industry, as they are associated with luxury and they have a “lush” feeling to them. Blue is by far the safest choice for many businesses (not only in the financial sector).

Website template

A lot of SaaS companies use a simple, minimalistic Apple-style website templates comprising white (or whitish) background, with a main colour theme. White is a crisp, fresh colour associated with purity and innovation, it also has a modern appeal to it. However, too much of a good thing can kill you - monochromatic websites with no (or very little) colour may offer too little stimulation. Most startups opt for blue and green website templates:

a) LiveChat - a lot of white spaces with red CTA buttons and a green chatbox stripe



b) SALESmanago - white + splashes of green

c) Blue seems to be the colour of choice for many SaaS websites, too. Perhaps it’s because blue is the favourite colour of majority of people (info here). Help Scout - blue as main colour + image of office workers.



d) Moz - spacious, minimalistic, with simple icons + a blue theme



A lot of successful SaaS websites feature either work-related images such as offices, work surroundings, customers, employees, or devices (laptops and mobile devices) on their homepage:

a) GoToMeeting - image of a tablet



b) Hootsuite - laptop



c) Positionly - employees



d) Kin - employees, office surrounding, blue



e) MailChimp does it really well - their homepage background picture suggests a friendly workplace for the creative mind









Call to Action Buttons/ Conversion Elements

Bright colours that really stand out tend to perform very well here. These include:

a) Green





b) Blue





c) Yellow, orange - so called “ugly” colours, like yellow or orange often turn out to convert well.



Colours are a great way to differentiate primary and secondary calls to action. Through contrast or selecting a much more visible colour, you can guide your visitor to perform the action you feel is more important:

a) Salesforce - 3 different colours for CTA options

b) Clicktale





Images & video

We love images because of the way our brains function - not only do we respond better to visuals than to plain text, we also process visual information much faster and tend to retain it much better (approximately 80% of visual data we see is retained). What is more, we have mastered the art of scanning and skimming online content, and currently only read as little as 20% of text on a website.

We are also highly emotional when it comes to visual images - studies show that people react emotionally to cutting up pictures of their childhood possessions, even though they are fully aware pictures have no physical relationship with the actual objects (as opposed to cutting up photos of control objects).

The power of images in website design is immense - an image speaks volumes about your website, product or service. It can also say a lot about your audience or brand identity. One of the key things you should remember when designing websites that images you select should imitate your target audience and things they like or use on a daily basis. As an example, a lot of websites use pictures of people using laptops and mobile devices.

a) Salesforce - use of video in testimonials



b) SurveyMonkey - use of video on the homepage helps outline the features of a complex product





Ticks

Another interesting thing is that Internet users tend to associate ticks with high performance, so it may be good idea to outline the features of your product or service in bullet points starting with a tick symbol. This is exactly what many successful SaaS companies are doing.

a) Hootsuite



Icons

Icons are a great way to convey meaning and prompt certain associations based on visual cues. SaaS businesses use these very often, as they get the message across without using up very valuable space on a website.

Keep your icons neat and simple to avoid confusion.

a) HubSpot - icons present multiple options



b) Scoop.it - icons illustrate the “how it works” section



c) GoToMeeting - product features illustrated by means of icons







Symmetry & Continuity

Because of the way our brains are wired, we have an eye for symmetry. Experiments show that averageness and perfect symmetry of a face make it more attractive. We also tend to favour websites which have a simple, logical order (also achieved my means of symmetry). Have a look at the GoToMeeting icon screenshot - the icons are aligned in two symmetrical rows, which makes this section of a website look neat and organized.

It is important your visitors know intuitively that they should (or should not) scroll on your website. When designing, exercise caution as putting certain areas together may suggest all content is already visible. Make sure your most information is visible above the fold, and if there’s more, encourage scrolling by making part of what’s below the fold visible. Remember that you should ALWAYS present your value proposition above the fold.



a) Kissmetrics



b) Wunderlist







The feminine side of SaaS, or Cialdini’s principle of liking

It seems that many SaaS companies choose an image of a smiling woman as their main image. The reason behind this is that we tend to comply with requests of people we like (Robert Cialdini).

a) Zendesk

This person’s appearance is all about customer service - she is very likeable and friendly, but doesn’t seem fake. The image seems to present a real person who you can trust. She doesn’t seem like a stock photo person, but rather an energetic customer service specialist who you can really talk to. Zendesk even included a video on their website presenting their Unique Selling Proposition (USP) , that is how close you can get to your customers based on their software. I am not totally convinced it is a good idea (check out the video yourself on their website), but it definitely differentiates them from other companies.







b) Shopify - image of a female customer holding a tablet









Trust cues

SaaS companies use trust cues in a number of ways, including padlocks, certificates, testimonials, and authority figures. They also present various data on their product, including number of users (preferably numbers of active users), mentions in universally recognized media, or partnerships.

a) Webpower - “as featured in” section





b) Colibri - authority figures used in testimonials





c) HubSpot - social proof in social media numbers







d) SurveyMonkey - social proof via numbers + renowned customers









...and things that violate trust

OK, so here’s a confession. One of our biggest mistakes when designing one of our first websites years and years back was to include an icon of a wallet with a dollar sign on it. The problem was that the website was directed at Great Britain. It is so basic, yet everyone nobody involved in the project noticed it as we operated internationally and used both pound and dollar symbols, so it didn’t look unnatural to us. For that reason, it may be a good idea to consult a specialist who is not involved in the project to take a look at it. If your marketing budget doesn’t allow for hiring a consultancy specialist, you can ask a friend or relative who is not a marketing specialist for their first impression of a website. You’d be amazed what you can find out.

The element of curiosity

This is particularly interesting, yet very risky. If you are not a household name (such as Neil Patel of Kissmetrics and CrazyEgg), instilling a sense of secrecy can be risky in the SaaS world. However, if your company is already quite prominent, you can try this approach and see how you perform.







Free stuff, or Cialdini’s Reciprocity Principle

Giving out things for free makes people more eager to give something back to you in return. A lot of SaaS companies offer free graders, trials (also without credit card details), or free reports of their potential customers. An example:







Conclusion

Although there are no universal solutions when it comes to website design, knowing how our brains work can help us produce more efficient, user-centered solutions. Of course, there are limitations as certain factors vary cross-culturally, but the takeaway here is to analyze your audience and imitate their thinking process.
