Search engines use massive data to rank what’s most useful to you, so yes they’re all about efficiency. But the same math that brings the best answer first also nudges you toward a narrower slice of content. If the algorithm rewards certain keywords or formats, you’ll see more of those and miss out on alternative viewpoints. From an SEO lens, it’s a double‑edge sword: optimize for relevance, but also be aware that the “most relevant” signal can become a filter bubble. So keep your content diverse, target different signals, and think of algorithms as a guide rather than a gatekeeper.
