Online persuasion: 7 ways to persuade people to buy
How many psychologists does it take to change a light bulb? None: the light bulb has to want to change. So the joke goes.
Of course, our light bulb could also be convinced or persuaded to change. And online conversion is as much about the art of persuasion as it is about want. It's little surprise then that online retailers often employ techniques and approaches known to marketers and psychologists.
At the end of the day, persuasion isn't rocket science; it's about understanding aspects of human nature that are often automatic and work at a subconscious level.
With that in mind, here are seven ethical ways to persuade people to complete their online purchase.
1. Show what other customers are doing
Humans are social creatures, and so we like to look to others and often do what they're doing, especially when we're uncertain about something. This psychological phenomenon is called social proof.
People feel reassured and often make decisions based upon what other people are up to – the assumption being that they possess more knowledge or are better informed than they are.
You can increase social proof online by showing:
- Most popular items
- 'Customers who bought this also bought'
- Top sellers
2. Include authentic reviews
User-generated reviews can have a massive influence on peoples' buying decisions. Fuelled by the rapid growth of web 2.0 and social media, they're becoming an essential part of website design.
Allow your site users to write reviews and express overall ratings for products and services on your site; after all, it's free content for your site. Web users are more inclined to trust what people like themselves say, compared to marketers. Reviews are especially critical in sectors like travel and electrical goods, although they're rapidly being adopted across all areas.
People generally want user-generated reviews and if they can't find them on your site, they'll simply look elsewhere. There's no hiding online, so you might as well have this validation on your own site. Sites like Figleaves and the UK Apple store website understand this and implement them really well.
Do not fear bad reviews! They demonstrate that your reviews are authentic and help establish trust. Instead, be prepared to act quickly on your customers' feedback.
3. Show scarcity of products
Scarcity generates demand and encourages people to buy sooner. People want what they think they can't have and social psychology would indicate that loss is a more powerful emotion than gain. So, a person who loses $100 is estimated to lose around twice as much satisfaction as another person will gain from a $100 windfall.
You can show scarcity online by displaying:
- 'For 1 week only'
- '2 items in stock'
- 'Sale ends today'
- 'Out of stock; add to wish list'
- 'This offer ends in 2 days 4 hrs 3 mins 17 secs' (Count down timers)
Research on decision-making also indicates that people value something more if they feel they lost out on it, rather than if they never had it in the first place.
4. Use rich imagery and videos
Imagery is a very persuasive tool in increasing product sales especially for high value and luxury goods, so be sure to provide good quality images of products. They go a long way to reassure people about what they'll be getting.
- Be of professional quality
- Offer different views
- Be enlargeable
- Show scale and context of use
Oli, which sells clothing online, has gone a step further. They have 15 second video clips of models wearing the clothing and walking down a catwalk, enabling you to get a better feel for how a product looks and moves. With increased bandwidths, this may be the future for some types of sites. Watching videos requires less effort than reading and offers a richer experience. Be sure to give users the choice and not to start videos automatically.
5. Cross- and up-sell
The person that suggested 'Hey, why don't we ask customers if they want fries with that?' was onto something big. Once people have committed to a purchase, persuading them to buy more becomes easier as one foot is already in the door. The same applies online too.
Don't underestimate the potential profits to be had by up- and cross-selling. Display related items and extras near products like they do in real stores. This will make it quicker and easier for people to buy more items. If you browse for bagels on Ocado, for example, they also show you cream cheese and when you checkout, and display any offers you missed out on – a clever tactic to persuade you to buy more.
6. Show your brand authority
The principle of authority states that we're more easily persuaded by those with authority. If Tiger Woods gave you advice on your golf swing, you'd be more inclined to follow it compared to the same advice from your mate, Bob. Likewise, websites showing authority and expertise are trusted more. This is particularly important for B2B sites.
You can show authority by:
- Showing you're an expert
- Backing up facts with links to third-party sites
- Referencing governing and authoritative bodies
- Displaying symbols and imagery of authority e.g. VERITAS, padlocks for security
7. Allay people's fears
What if I need to return items? Are there any hidden costs involved? These are the sorts of fears web visitors may have and you need to reduce them if you want to persuade people to do business with you. Answering their concerns upfront and quickly will positively influence people and lower their fears.
Persuasion in its simplest form means giving users the information they need to make an informed choice, helping them to trust you and allaying any concerns they have. It's not about manipulation. Always remember that these persuasive tactics will only get you so far; your site still needs to provide a good service and be highly usable to guarantee success.
