Boosting Ecommerce Conversion: 5 Behavioral Science Tips

Brands often spend substantial resources on ads to drive website traffic, but rarely optimize ecommerce conversion rates enough to turn increased traffic into sales.

While ecommerce conversion rate optimization may seem daunting at first, researchers of behavioral science have taken great strides in the last decade to further our understanding of buyer behavior. By designing solutions that align with our psychology, we can make it easier for people to do things they already want to do.

Marketers who apply the following 5 principles to ecommerce websites are poised to increase ecommerce conversion.

Structuring Your Navigation Bar

Most marketers randomly add menu items and CTAs (call to action) without thinking about consumer behavior. 

Visitors of ecommerce websites (and all others) first look to the right, and then to the left of the web page. The center of the page will always get short shrift from users.

You should place your main CTA on the upper right, 2nd most important item on the left, and the least important in the middle of your navigation bar.

These insights are critical when determining where to place important content blocks. Applications such as Hotjar that visualize website heatmaps are useful tools that help webmasters optimize website use.

Prevent Information Overload

When it comes to presenting information on the products offered, the adage ‘less is more’ holds true. There have been many studies illustrating that an excess of information that is not critical to the purchasing decision will actually impede conversions (see this study from researchers at the Soochow University in Taipei). In fact, users much prefer web pages that are simple and familiar (see a Google study from 2012).

A very clear navigation menu where people can discern where they need to look for products in which category, what is new, what is on sale, etc. will go a long way in providing visitors with the guidance they need to find and purchase the products they want. 

Product pages that aren’t cluttered with random details and images also fare better. Keep product pages as short as possible and as clean as possible.

Lastly, checkout funnels that are clean with clear directions will boost conversion rates compared to pages that have irrelevant information.

Use Social Proof

Social proof is one the original seven principles of persuasion famously proposed by Robert Cialdini. People will be more willing to buy a product if they know that others have bought it as well and preferably also recommend the product.

Ecommerce websites can no longer go without highly performing recommendation engines that share information on what others think of what the brand has in store. Recommendations are not only of critical importance for conversion rate optimization on the website, but also show up in Google SERPs, making them even a critical part of SERP conversions.

Avoid Friction, Especially on Mobile

Website visitors abhor having to jump many hoops to accomplish simple tasks. This applies equally to both desktop and mobile versions of websites, but we still see most problems arise with mobile applications where checkouts often become strenuous.

We understand that ecommerce businesses would rather not pay fees to Apple or Google for using Apple/Google Pay, but the cost of having customers struggle with inserting credit card information manually and abandoning a purchase mid-process is likely to dwarf whatever they’re charging the business.

Friction of any kind will always hurt sales.

Provide What They Expect

Whether you like the typical makeup of an ecommerce website or not, there is a common template in use with ecommerce sites that people have gotten accustomed to. When you present a website that looks different from the typical site people have come to expect, your conversions will suffer.

The aforementioned Google study affirms that people prefer websites that are “prototypical” of their categories.

Bottom Line

Website design is critical for ecommerce businesses in any vertical that want to optimize their conversions. While the task at hand might look daunting at first, valuable research is available on many aspects of website design, from content placement and density to social proof and friction avoidance. Ecommerce managers that apply evidence-based best practices will optimize conversion rates and grow their bottom lines.
