Classifieds apps used across Malaysia fill quickly with listings that never take a call. A new seller can upload three photographs of a sofa, set a price copied from a neighbour, and disappear. Counting that upload as activation congratulates the camera roll, not the market.
In studies we have written for second-hand and services classifieds, the stall that matters is the first inbound reply that the seller answers within a working day. That is when the person accepts being interruptible. Listings without replies, and listings with replies that sit unopened, belong in a different paragraph.
There are categories where the listing itself is the commercial act — a spare-parts catalogue aimed at factories in Perai, for example, where buyers search SKUs rather than chat. The report should name that exception. The mistake is treating the exception as the default.
If your current dashboard lights up when a listing is published, keep that light. Just do not call it seller activation in a document that is supposed to tell you whether supply is real. Ask whether a stranger could complete a purchase or a booking against that listing this week.
