A grid impression is not a product page
Scrolls, sponsored tiles, and accidental taps inflate ‘views’ until a PDP open is named as its own event.
Home grids in fashion and electronics apps are long. A shopper can pass forty tiles without meaning to “view” any of them. If every tile that enters the screen writes a view event, category performance becomes a story about scroll depth, not desire.
The useful pair is impression (tile on screen, if you must have it) and open (the product page actually loaded). Filter changes should not replay impressions as new interest. Sponsored tiles, where they exist, need a flag or they will be praised for a placement merchandising did not choose.
In catalog search reviews we sample queries such as “kasut sekolah” or a brand the desk is trying to clear. We care whether the open event matches the SKU the shopper tapped, including colour swatches that swap the identifier underneath the same tile.
