Discover works fundamentally differently from search: there's no query to target, so 'ranking' for Discover isn't really the right mental model — instead, content gets surfaced based on topical relevance to what a user has shown interest in, combined with content freshness and quality signals. High-quality images play an outsized role in Discover performance, since large, eye-catching visuals are a core part of the feed's format, and Google's own guidance recommends large images (1200px or wider) with the max-image-preview:large setting enabled for eligibility. Discover traffic tends to be feast-or-famine — a single piece can drive a large, sudden traffic spike if it gets picked up broadly, then drop back down, which makes it a genuine traffic source but a volatile one to plan around.
Example
A timely explainer article gets picked up in Google Discover feeds two days after publishing, driving a 400% traffic spike over 72 hours before settling back to normal organic levels.
