Lessen their efforts by providing your website with clear and effective information architecture. Customers could benefit from a website’s information architecture. When they can easily spot relevant information and decide upon their next action to take.  

2. Avoid over-designing your website

You want to aim for simplicity as much as possible. Light color combinations are recommended, and photos should be appropriate with what the page is trying to present. Balance each element of your e-commerce website to bring a pleasant yet impactful effect on your customers. 

3. Be cautious of physical interaction  

Do customers need to scroll endlessly to navigate to the information they are looking for?  

We get tired from typing on our keyboard and clicking on the mouse for periods. So imagine when you have to ask your customers to exert these physical efforts to get from one information to another.  

Optimize your e-commerce site by organizing products and services so that core information is laid out on one page. Make links accessible and related to the page so that clicking can be minimized. It is also helpful to make questions simpler on forms to reduce typing.  

4. Double-check the scannability of your site 

As part of the visual element which contributes significantly towards customer experience, you want to ensure that the customers catch every content in your website.

7. Make your forms short and simple 

Part of e-commerce websites is filling out forms such as when customers are ready to make a purchase. You don’t want customers to feel like they are signing contracts or stress themselves because they can’t understand questions being asked in the form.  

Make sure to include appropriate questions only, such as basic personal information, delivery address, or contact details. You may also want to place an indicator to show how far customers have progressed in answering the questionnaire, so they’ll know how near they are to completing the form. 

Complications in filling out forms may also be why even the best e-commerce customer service receives complaints. So, make sure your online forms are simple to rid the customers of unnecessary steps.  

8. Provide field hints to guide customers 

Time is of the essence when it comes to interaction cost. Customers do not like to waste their time stuck answering a form just because the format for typing their address is incorrect, for example.  

If this happens, the customer decides to exit the website and move to another one with more detailed requirements. Avoid this by providing field hints such as an inline text placeholder, an annotation, or even graphics to illustrate what customers should do.
