This is a common point of confusion: an impression doesn't require the result to have been visibly rendered on the user's screen, just present in the results returned for that query — which means impression counts can look inflated relative to what a user might describe as actually 'seeing' a result. Impressions are most useful read alongside clicks and CTR together, not alone: rising impressions with flat clicks can mean a page is appearing for more queries but not earning attention (a title/meta problem, or a low ranking position within the results), while rising impressions with rising clicks proportionally is a healthier growth pattern.
Example
A page's impressions triple after a content expansion covers more related subtopics, but clicks only grow 20% — a query-level breakdown shows most new impressions come from a position 40+ ranking, too low to earn clicks yet.
