When it comes to marketing and persuading customers, science can be just as effective as art.
In fact, using scientific principles of persuasion can often be more effective at increasing customer conversion rates than traditional advertising techniques.
This article will explain three major psychological principles of persuasion — the Milgram Principle, the Decoy Effect, and the Ben Franklin Effect—and provide examples of how you as a marketer or business owner can use each one to improve customer conversion rates on websites and apps.
Milgram Principle
First up is the Milgram Principle. Named after psychologist Stanley Milgram who devised the famous experiment exploring obedience to authority figures in the 1960s, this principle basically states that people are more likely to obey a request if they believe it has come from an authoritative source.
This authority can be real, such as a well-known celebrity or expert in the field, or it can be perceived through the use of design elements and language.
For example, you can emphasise a call to action with bold font and vivid colours to make it stand out from everything else on a page. You can also use authoritative language like “must” or “instantly” to give your message more impact.
The Decoy Effect
The Decoy Effect is another powerful persuasion technique that taps into people’s natural tendency to compare options against one another when making decisions.
The idea here is to offer customers two similar items but with one being slightly better than the other in some way.
This causes customers to focus on the differences between the two items and makes them more likely to choose the better one.
For example, if you’re selling a subscription service, you can offer customers a basic plan for £5/month and a premium plan for £10/month.
The decoy here is the basic plan - the idea is to make the benefits so basic compared to the premium plan that the extra £5 per month for the premium makes the most sense.
Ben Franklin Effect
Finally, there’s the Ben Franklin Effect. This technique essentially says that people are more likely to do favours for someone they already like than for someone they don’t know or have no opinion on yet.
You can use this principle by offering existing customers exclusive discounts or special offers in exchange for their loyalty—this not only makes them feel appreciated and liked, but it also encourages them to make additional purchases.
Another to apply the Ben Franklin Effect is through content marketing—if you’re producing great content that your target audience finds valuable and entertaining, they are more likely to become customers even before they have interacted with your company directly.
In conclusion, using scientific persuasion techniques in marketing can be a powerful tool for increasing customer conversion rates on websites and apps.
The Milgram Principle helps customers consider an authoritative source when making decisions; the Decoy Effect gets customers to compare options side-by-side; and the Ben Franklin Effect encourages people to like your brand in order to increase sales.
