The traffic advantage isn’t about having fewer URLs, it’s about user engagement quality and content consumption per session, and it only materializes when the load-more implementation keeps the underlying content genuinely crawlable rather than trapping it behind pure client-side interaction. The mechanism people often misattribute this to, “fewer URLs are inherently better for SEO,” isn’t actually the driver; a well-built load-more pattern and a well-built numbered-pagination pattern can both perform well, and a poorly built version of either can underperform, because the real variables are crawlability and user engagement, not URL count.
Why “fewer URLs” isn’t the actual mechanism
There’s no documented Google ranking benefit to simply having fewer paginated URLs. Google’s crawling and indexing systems don’t reward a site for consolidating content into fewer pages purely for its own sake; what matters is whether the content that exists is genuinely accessible, well-structured, and provides real value on whatever URL structure hosts it. If load-more pagination were winning purely because it produces fewer URLs, that would imply URL count itself is a negative ranking factor, which isn’t something Google’s documentation or engineer commentary supports. The actual explanation lies elsewhere.
The real driver: engagement signals from more content consumed per session
When load-more pagination is implemented well, typically with progressive enhancement where clicking “load more” fetches and appends genuinely crawlable, indexable content rather than purely client-side-rendered fragments, users tend to consume more content in a single session before navigating away, since there’s no interruption of clicking through to a numbered “page 2” and reloading a new page shell. This can translate into stronger engagement signals: more content viewed per session, potentially lower bounce rates, and longer time on page. These are the kinds of user-experience-quality signals that indirectly support ranking performance, rather than load-more pagination directly benefiting from having a smaller URL footprint.
Numbered pagination, particularly when implemented poorly, tends to produce a different failure mode: individual paginated pages (page 2, page 3, and beyond) that are thin on their own, containing only a fraction of a topic’s full content, and that struggle to rank independently or to hold users’ attention since each page requires a full navigation action to continue. This isn’t an inherent flaw in numbered pagination as a pattern, it’s a common implementation problem where each page is treated as a disconnected unit rather than genuinely valuable content in its own right.
As a hypothetical example, imagine a hypothetical recipe site, “Site B,” that switches its recipe-index page from numbered pagination to a load-more pattern built on History-API-driven URL updates, so each batch of loaded recipes still corresponds to a real, crawlable URL. Hypothetically, if average session duration on that index page increased and users viewed more recipes per visit because they weren’t interrupted by full-page reloads between “page 2” and “page 3,” that engagement increase, not any reduction in URL count, would plausibly be what’s actually contributing to a subsequent organic-traffic improvement.
The crawlability requirement that makes or breaks either approach
The technical crux that actually determines whether load-more pagination helps or hurts is whether the content loaded via the “load more” interaction is accessible to Googlebot independent of a user’s click. Google’s JavaScript SEO guidance is explicit that content relying purely on a user-triggered interaction, with no corresponding crawlable URL or server-rendered equivalent, isn’t something Googlebot will discover the way a human user would; Googlebot doesn’t click buttons to reveal more content the way a person browsing the page does. A load-more implementation that appends content via a URL update (using the History API to expose a real, bookmarkable URL for each batch, or serving the same paginated content through a hybrid pattern accessible without JavaScript) preserves crawlability. A pure client-side implementation that never exposes a crawlable path to the additional content risks Google never discovering everything beyond the first batch at all, not just weakly ranking it.
This means the “fewer crawlable URL paths” framing in the premise of this question is actually describing a risk, not a benefit: if load-more genuinely reduces crawlable paths to real content, that’s a liability, since content Google can’t discover can’t rank regardless of how good the user engagement metrics look. The cases where load-more “outperforms” numbered pagination for organic traffic are specifically the cases where the underlying content remains fully crawlable through some URL-exposing mechanism, and the performance gain comes from the engagement-quality side, not from actually having fewer discoverable URLs.
The practical implication
When evaluating whether to use load-more or numbered pagination, the deciding factor shouldn’t be an assumption that one URL pattern is inherently more SEO-friendly than the other. It should be: does the implementation keep every piece of paginated content accessible via a real, crawlable URL regardless of the UI pattern, and does the UI pattern chosen genuinely improve the user’s experience of consuming that content. A load-more pattern built without crawlable URLs behind it can quietly lose organic visibility for everything beyond the first batch, while a load-more pattern built correctly can capture a genuine engagement-driven traffic benefit. The URL-count difference between the two approaches is a side effect of the implementation choice, not the mechanism actually responsible for any traffic difference observed.
