An Introduction to Biometric User Testing

What is Biometric Testing?

Biometric User Testing is relatively new on the digital marketing scene. Don’t panic - it’s really not as scary as it sounds. Essentially, it applies the principles of psychological testingtechniques to the context of digital marketing. That translated? It is used to test and record the responses of users when interacting with retailers’ websites and apps. Both emotional arousal and stress reaction measures are used in order to achieve this and data is then collated to provide insights on the findings.

How does Testing Work?

Testing a sample using qualitative and quantitative data, opportunities for these refinements quickly becomes apparent in the data reports. Subjects are selected to match the demographic profile of the website being tested. They are set up in a Biometric Laboratory, which guarantees consistency in the testing environment. The testing itself involves the application of various measures, including: Galvanic Skin Response (similar to polygraph testing in measuring palm sweat levels), Eye Tracking (what the subjects are looking at on screen), Mouse Tracking (what the subjects mouse is doing on screen), Facial Expression Analysis and Attention Analysis (captured with various user cameras during the testing session). Subjects also provide direct feedback on their experience using the website, usually in a series of questionnaires and surveys. Subjects are given several tasks to complete on the website, such as searching for a specific item, and proceeding to cart checkout. This testing process usually takes around one hour per subject and is highly valuable to highlighting key issues with eCommerce and functionality and overall usability. A deeper level of analysis can be achieved by repeating this testing process again with the same subjects, but this time performing the same test on competitor websites. This highlights the areas of success and improvement for an eCommerce site in the context of competitor presence.

How is it Applied?

Unsurprisingly, Biometric Testing has seen its early adopters in the mega eCommerce Retailing Market (think the big online supermarkets like WholeFoods, travel booking sites like Skyscanner, and marketplaces like Amazon). The reason being that they all have huge traffic volumes and huge online sales in common. When it comes to refinement, or optimization of their eCommerce site, a small tweak can mean the difference of millions of dollars in sales. So their common interest is in complete eCommerce refinement for the ultimate User Experience. But the benefits of Biometrics are now being recognised by smaller businesses too, and rightfully so. In a culture where a smooth online experience is so vital to successful business, particularly when financial transactions are involved, public expectation is constantly growing. This isn’t just isolated to big business - consumers have come to expect this now of all eCommerce interaction.

Now What?

If you are in the business of eCommerce, it’s time to consider if Biometric Testing  is a marketing method you should be applying. As a general rule of thumb, the greater the site traffic, the greater the potential for achieving big results. So, if you are only just starting up, it may not be the right time for you. If you are a bigger business, with a robust online presence and marketing team, this could be your big opportunity for untapped growth in 2019. With User Experience and Conversion Optimization being high on the agenda for most digital teams, it’s time to consider if Biometrics Testing should become part of your ongoing digital strategy. Remember, when it comes to website traffic, users expect a seamless journey. The only way to truly test how your users interact with your site, and to identify any common pain points they may have, is to apply Biometric Testing.

Colour Psychology: Increase Sales With One Simple Change

The colours you choose lay the foundation for your online image so it's important to choose carefully.

Web design sounds fancy. Yet, like all elements of conversion rate optimisation, building a website is more about construction than design. The colours you choose lay the foundation for your online image so it's important to choose carefully. Using colour psychology not only helps you look good, it can help attract the right kind of customer to your website and increase conversions.

What is colour psychology?

Colour psychology is the study of how people are affected by colour. You can test how powerful colours are just by thinking of some of the biggest brands in the world. What colour do they use? You'll recall it instantly for Coca-Cola, FedEx, Nike, and Facebook. You also know Coca-Cola is pillar-box red, not burgundy. FedEx is a rich purple, not lilac. And Facebook is a muted blue, not sky blue or sapphire.

Now think about how those brands make you feel. It's common knowledge that red represents a 'bold' attitude and pink points to products for women. But do you know that purple divides people by gender? Women are drawn to it and men are not. These findings reveal how people might react to your website.

What do colours mean?

Site visitors take just 50 milliseconds to make a judgement about your brand and colour plays a key part in this. No doubt you're already familiar with some of the basic assumptions of colour psychology:

  • Blue and green are universally popular. Blue is steady and reliable; green is fresh and calm. An edgy brand wouldn't go for these colours, but a corporate or more reserved company might.
  • If black, white, and grey are flat, unemotional colours (frequently used by tech and engineering companies), red, yellow, and orange are stimulants. These warm colours grab attention, generate excitement, and can create a sense of urgency.
  • Where pink is mostly associated with girls, purple is the grandmother of the colour chart. Pink is energetic and youthful, but purple oozes calm and wisdom.
  • Poor brown is typically unloved. Yet nobody can pooh-pooh the success of UPS – it's still going, since 1907. Brown is a rich part of the company's history and the colour of the original uniform.

The thing that makes colour psychology so interesting is that, despite the trends, everybody is different. People can become obsessive over a particular colour. Just the sight of it can stoke an old memory — good or bad. It's this reaction to a colour trigger that you can test in conversion rate optimisation:

  • What does your audience respond to?
  • Which colours work best in your niche?

How to use colour psychology in web design

Number 1

Use harmonious colours to keep people on the site

The last time you read about complementary colours might have been in school.

If you remember, these are the colours opposite one another on the colour wheel: red and green, blue and orange, yellow and purple. The colour wheel has been around since 1666. It was invented by Sir Isaac Newton and used by Claude Monet. Ever since then we've trusted that these pairings are pleasing on the eye.

More modern depictions of the colour wheel show twelve colours, which make up the RYB (Red-Yellow-Blue) colour chart. For web design, you can pick three colours that sit next to each other on the wheel because they'll always hang nicely together. Or draw the corners of a triangle, rectangle, or square shape evenly within the wheel; the corners pinpoint the selection of colours. These will always work well together because they're part of the same tried-and-tested RYB chart.

Number 2

Keep colours consistent for a dramatic increase in conversions.

Research by the University of Loyola in Maryland suggests that sticking to the same palette of colours on your website can increase brand recognition by up to 80%.

If you don't want to mix colours, add black, white or grey to just one colour to create a different hue:

  • Make a colour lighter by adding white (tint)
  • Make it darker by adding black (shade)
  • Change the intensity by adding grey (tone)

A selection of different tints, shades, and tones of your chosen colour can form a colour palette too.

Number 3

Add accents of colour to prompt people to click.

Think about the conversion elements on your website. All the thought that goes into the headline, the description, the navigation, the images, and the button placement.

Do you give the same amount of thought to the colour of these key areas? Is it clear to your viewer what they should click on next?

In the EE example below, they highlight the headline and the button with a flash of yellow.

To keep colours balanced, not garish, use this design tactic:

  • Establish your brand colour by using it across most of your site (60%)
  • Make the brand colour stand out more by using a contrasting colour in places (30%)
  • Highlight areas key to conversion by using an accent colour sparingly (10%)

Think about the colour you use to showcase headings, navigation, buttons, and hyperlinks.

Tip! Background colour affects conversion.

Most websites have a plain background and lots of white space because it makes the text easier to read. Breaking convention with yellow text on a grey background may feel rebellious, but is it a smart move if nobody can read it? If your message is lost, your sale is lost too.

Conversion experts don't guess

Get to know what each colour means and it could give you an advantage in your optimisation strategy. Your next test could reveal something unexpected that turns a poorly performing page around.

  • Colour specialist, Carlton Wagner, once claimed yellow "activates the anxiety centre of the brain". If you're a gentle brand with a peaceful product, you should test yellow against green.
  • The University of Rochester suggests red makes people nervous when taking a test. If you're in the education sector, you might want to avoid red buttons on your website.
  • Orange is said to be a polarising colour; people can hate it as much as they love it. It's worth testing orange with your audience before you launch.

What works for one website won't work for another. Not all women like pinks and purples and some people love brown. Test it in your niche to avoid a flop—like Heinz, who famously tried and failed to launch a green version of their tomato ketchup. Parents didn't respond well to the conflict of colour. Kids didn't like it either because they associate green with vegetables and food they don't favour.

Putting colour psychology to the test (and winning)

When VegasSlotsOnline.com changed a "Sign up here!" button from green to yellow, they saw a 175% increase in conversions. Conversion optimisation is all about human behaviour and this brand knows their customer well. Because of that they were able to test what they thought might be most successful:

"Psychological effects of colour do matter. In our case, we chose two colours, both of which produced convincing arguments for their use. Our test likely would not have been fruitful if we had used white or black buttons. Our niche’s characteristics were paramount to our colour selection."

Try out colour psychology on your own site design

Will colour psychology testing work for you? If you work in conversion, you know there's only one way to find out: Test it. Find out if choosing one colour over another changes the way people behave on your website. It might just result in more click-throughs and more sales.

Customer Feedback, Relationships and Reviews

Reviews Matter: How to Build a Better Relationship with Your Customers

Some easy tips and tricks on how to make the most of reviews on your website and increase credibility

Having a good relationship with your customers is arguably the most important part of running a business. After all, happy customers, happy conversion rate.

And one quick, uncostly way to do that is through reviews.

According to statistics, ‘92% of people will trust a recommendation from a peer & 70% will trust a recommendation from someone they don’t know’. And with more than one in ten customers reading online reviews, your customers will be your best form of marketing.

Having a product reviews section on your website will mean your products have the backing from your consumers. Those that have bought, tried and tested, your products will be able to review them for other potential consumers that may be browsing the site (and hopefully they will be vouching for you).

Equally, it is important to never remove any negative reviews. This would be dishonest, and that isn’t the message you want to be sending out where your business is concerned. Instead, E.g. if a review says "My product arrived late" replying and saying "We're sorry for the confusion, please get in touch and we're happy to refund your delivery". Customers understand that things go wrong and more interested in the solution.

This approach will appear more professional and suggest that you care about your customers and about improving not only your product but your business. Make the most of these comments. It’s a good way to see things from the other side too!

And it’s not just written reviews. Thanks to social media, your customers can now give you social testimonials.

So for instance, let’s say your business is fashion related. A customer may post a photo of her new dress on social media. She just can’t wait to wear it out this Saturday and tags you in the caption or mentions your brand when one of her friends asks “where’s it from?”. Now, all of her friends and followers that saw her post are aware of who you are. They may even visit your site. And one great tool you could use to help with this would be Yotpo. They allow you to “combine reviews and photos with customizable display options that enhance your brand”.

Whether you’re in the fashion industry, tech, sports, whatever it may be, ultimately the principle works the same. People buy from people.

So not only can reviews potentially make your products more credible but if used in ways like social testimonials, it can generate advertising and reach extra audiences you may not have otherwise.
