Infinite scroll has change into virtually synonymous with fashionable net design. It would really feel smooth, immersive, and frictionless — no ‘subsequent web page’ button to click on, only a clean river of content material that by no means appears to finish.
However right here’s the truth — Infinite scroll is usually a entice. Whereas it seems to be fashionable, it might probably severely harm accessibility, efficiency, and consumer expertise. On this submit, we’ll unpack the infinite scroll entice, present you why it’s problematic!
How infinite scroll works
At its core, infinite scroll is a design method which hundreds content material repeatedly because the consumer scrolls down. Additionally known as countless scroll, the purpose is that the consumer by no means reaches the tip of the web page. As an alternative, they’re introduced with a perpetual content material stream with out having to click on.
Why infinite scroll appears fashionable
- Frictionless searching: Arguably, the largest benefit of infinite scrolling is that it reduces interruptions and that the customers don’t should click on ‘subsequent’ button.
- Retains customers engaged: Countless feeds typically really feel immersive.
Why is it problematic?
Accessibility nightmares
- Display readers: Steady content material updates can disorient customers. Some display screen reader customers may suppose the web page could be very lengthy and may miss the footer area utterly, particularly whether it is pushed out of attain.
- Focus points: Newly injected content material can seize focus unexpectedly or depart the consumer misplaced.
- Cognitive overload: Customers with ADHD, dyslexia could wrestle with by no means -ending streams of content material.

Right here’s an excellent listing of checkpoints from the article So You suppose You’ve constructed a Good Infinite Scroll by Adrian Roselli that’s price checking earlier than you contemplate implementing infinite scroll.
Efficiency prices
- Reminiscence bloat: The DOM grows endlessly. Each new batch of things provides extra DOM nodes, photos, occasion listeners, and CSS reflows. This simply retains appending content material indefinitely and this might result in sluggish efficiency.
- search engine optimisation challenges: Infinite scroll typically hides content material outdoors of a crawler’s visual field. Search engine crawlers usually solely see the initially loaded content material, not what seems later as you scroll. If the crawler can’t entry that further content material, it might probably’t index it — which implies massive elements of your web page could stay invisible in search outcomes.
Higher alternate options
You don’t should ditch dynamic loading — simply give customers the management.
- Pagination: With pagination — merely splitting content material into completely different pages and linking to those pages on the foot of a web page — customers have a way of the place they’re within the data hierarchy. They know what number of pages they should navigate they usually get to decide on whether or not they go to these pages or not. Seen in that gentle, pagination provides customers again the management that infinite scroll takes from them.
- “Load Extra” button: This includes exhibiting a sure variety of outcomes per web page; beneath these outcomes there’s a button that asks if a consumer desires to see extra. Once more, this lets customers resolve when to fetch extra content material. One factor to notice — place new content material after the “Load extra” button, not earlier than, so the main target order stays logical, and keyboard-only and display screen reader customers can proceed navigating ahead, with out being disoriented. (If the extra content material was positioned earlier than the button, and the main target remained on the button, how would a keyboard-only or display screen reader consumer get again to the beginning of the content material that had been added?)
Some customers depend on landmark areas (,
and many others.) to rapidly bounce round content material — thus far, display screen readers are the one assistive expertise to totally assist this. Offering landmarks for content material that comes after the infinitely scrolling space of the web page could appear to be an answer — nevertheless it received’t assist keyboard-only customers. So, it’s not a whole repair at this time, although it would change into simpler sooner or later.
Should you’re a keyboard-only consumer, or an online content material writer, and wish to navigate landmark areas through the keyboard, or visualise the landmark construction of your web page within the developer instruments panel, you possibly can use an extension comparable to the Landmarks browser extension.
Remaining ideas
Infinite scroll isn’t a one-size-fits-all answer. When used with out due care, it creates extra issues than it solves. Nonetheless, with considerate design we might improve the expertise permitting all customers to entry the online content material and performance. In the end, giving customers management is the important thing to a greater expertise.
