“Oh, god, I hate these, go away. NOO! Go. Away. If I wanted chat I would ask for it.”
It is not uncommon for users on e-commerce to encounter difficulties at some point during their product finding journey. A little help can go a long way and being proactive when it comes to offering that help, through a feature like live chat, makes sense. At least, in theory.
In practice, however, all of our large-scale usability testing of e-commerce has shown that live chat is a feature that isn’t relied upon that heavily, especially considering the prominent placement it often has. Instead of being perceived as a helpful feature, most users generally perceive live chat as just another annoying, site-initiated distraction when it appears.
Three live chat approaches that we’ve observed during testing — overlay dialogs, dialog pop-ups, and sticky/floating chat elements — all carry UX problems that should be taken into consideration during implementation. What at first may seem like a help can quickly become a hindrance for users.
That said, the general principle of offering live chat isn’t bad in itself; it’s mainly how and when it’s initiated that causes issues for users — and during testing we have also observed one pattern that generally performs well with users, which we’ll cover at the end of this article.
This article will cover some of the common pitfalls we’ve observed during our large-scale usability testing when it comes to Live Chat on both mobile and desktop — issues that many e-commerce sites suffer from in their live chat implementation. We’ll discuss the effects of some of these implementations and how they can be avoided, including:
- Three popular live chat approaches and the UX issues they cause
- Sticky live chat elements are especially problematic for mobile users
- How and when live chat is observed to perform well
Three Popular Live Chat Approaches and the UX Issues They Cause
Many users enter an e-commerce site with a clear intent or purpose — to look for products. When they are unduly interrupted or disrupted in this journey, they are taken a little further away from being able to complete their task. If this happens too often or too severely, it could result in abandonment entirely.
During our large-scale usability testing, we experienced 3 popular approaches to live chat that can each cause issues for the user, depending on functionality, response, and placement.
1) Overlay Dialogs
Overlay dialogs – that appear on top of other content on the page – may seem like a useful way to make the user aware that live chat is available and ready to help. For the sub-group of users that would actually benefit from assistance this could be seen as a positive, but in that very same moment this interruption may be warranted. In practice the live chat dialog never only appears for those users who could use help, and never exactly when they need it. Live chat overlay dialogs come at the cost of disturbing the vast majority of the users who just want to continue with their product exploration without being disturbed.
During testing, live chat dialogs are experienced by users in much the same way as overlays that appear on page load: annoying interruptions that disrupt them from their current task. For the vast majority of users, a live chat overlay dialog is simply a minor annoyance, which they must dismiss in order to continue on with their product browsing. For others, like in the Macy’s example above, live chat can contribute to the general “buggy” feeling of a site, especially if the site has other technical issues.
2) Dialog Pop-Ups
Another live chat implementation is dialog popups. These differ from overlay dialogs as they do not usually take up the entire screen and in many instances the user is still able to continue with their actions on the page without having to close the popup first. However they typically still require some interaction in order to close or minimize them if they start getting in the way.
Again, it may seem like a good way of letting the user know that the feature is there. However, non-user-initiated live chats are experienced by a minority of users as “pushy salespeople”, the equivalent of overly aggressive store employees asking if you want help while at a brick-and-mortar store. For these users, being asked if they “Need help today? Chat with an expert.” reflects poorly on the site and brand. This is especially the case when chat dialogs appear multiple times while on the site, or when it’s difficult to close due to a small hit area.
We also observe that a smaller subset of users, typically more insecure web users, will never close these dialog pop-ups, and just continue to browse the website with a reduced effective viewable area.
3) Sticky Chat Elements
The third popular approach for live chat that we observe to often cause UX issues is having it as a sticky or ‘floating’ element throughout all or most of the sites, e.g. a chat “bubble” that’s constantly in the user’s viewport or a button on the edge of the page. While these may or may not actively interrupt the user during their journey by trying to initiate a conversation, their presence can still be disruptive to the user. Their constant appearance or ‘stickiness’ on the page means that there is a high likelihood that the live chat element will obscure or obstruct another feature at some point.
Sticky Live Chat is Especially Problematic for Mobile Users
Desktop sites have the luxury of screen real estate that mobile sites simply can’t afford, so the mobile screen real estate is precious as it is so limited. While the implementation of a sticky live chat means that users are never far away from accessing help, our testing reveals that on mobile websites these sticky chat elements often block key page content in much more obtrusive ways than the same sticky element will do on a desktop site. When sticky live chat appears nearly universally on the site (e.g., in search results, on product pages, in the cart, etc.), it’s difficult if not impossible for site managers to foresee all the different instances where key content or features may be blocked by the sticky chat element (e.g., autocomplete results, buttons, filters, text, etc.).
Live chats that are implemented as sticky elements (typically) also can’t be dismissed the way overlays can. As one user said while trying to read a product description that was partially blocked by a live chat feature, “I can’t read it. Can I move that? No.” Even when the sticky live chat feature is designed to be as small or inconspicuous as possible, it can still cause issues for users, as on mobile nearly all of the interface is valuable (and already taken by other content or features).
Finally, on mobile, typing is quite difficult compared to desktop due to the intrinsic issues with the small touch keyboards and available space, and thus users may generally be more hesitant to even use live chat while on the mobile site.
On desktop, it’s less likely that sticky chat elements will overlay key content, given that the live chat sticky element will be relatively smaller compared to the rest of the viewable page area, and we observe that users generally have less trouble dismissing chat overlay dialogs or sticky elements. Hence, chat dialogs (if intelligent) and especially sticky chat elements are generally more warranted to have as desktop-only features. Nevertheless, it does not change the fact that site-initiated live chat still represents an unasked-for annoyance that can interrupt desktop users at critical moments in the product-exploration process.
How and When Live Chat is Observed to Perform Well
Live chat can be extremely helpful, however, when users decide they need it. For instance, during our Accounts & Self-Service testing many users actively sought out live chat when they had questions about return policies, refunds, or shipping. However, the key difference in these instances was that the users themselves sought out live chat — live chat didn’t interrupt the task they were currently involved in.
Therefore, for live chat to be viewed by users as helpful rather than disruptive it must be user — not site — initiated. It should also be placed where users will expect to find it — particularly in the footer (see Have Direct Links to “Return Policy” and “Shipping Info” in the Footer), header, and as direct links within the help section of a site, as our testing have shown those are the areas where most users tend to look.
If the live chat feature must be site initiated, then take active steps to mitigate the disruption it otherwise causes for all users. These can include making some pages off-limits for live chat (e.g., when users are in a filtering interface or are in the checkout flow), being conservative when deciding how often to show live chat to users (often once is enough, so they are aware the feature exists), and having a time delay before showing live chat, which at least takes into account whether a user has had a chance to browse the page content before they’re interrupted.
When live chat is implemented appropriately, the help and reassurance that it can offer the user cannot be underestimated. What’s important, however, is not to force the feature down the user’s throats. As with many site-wide features, this will be a fine balance between design and implementation to provide help without hindrance to the various users that visit your site. What’s important to remember is:
- Avoid disrupting the user’s flow with non-user-initiated live chat overlays or dialogs. Let the user, not the site, initiate the live chat conversation.
- Be especially mindful of any inclusion and placement of sticky live chat on mobile sites, where they are more harmful than on desktop sites.
- Make the live chat feature accessible to those that need it (like placing it in the footer), without being obstructive to those that don’t.
