Weight creeps up through large images, bulky JavaScript, multiple fonts, and third-party scripts (analytics, chat widgets, ads) that each add to the total. Any one seems small, but together they can bloat a page to several megabytes.
Trimming page weight (compressing images, cutting unused code, limiting third-party scripts) is one of the surest ways to improve every speed metric at once. A lean page loads fast even on a weak connection, which is where a lot of real traffic actually is.
