How filtering by in-stock items removed friction when urgency was highest.
If your products sell out fast during the holidays, hide sold-out items to keep momentum (and conversions) high.
During Black Friday or high-traffic weeks, shoppers click into a collection page and hit a wall:
Nothing they want is in stock.
That kills momentum, creates frustration, and costs you sales.
So we tested a fix:
For a fast-moving catalog, we auto-applied the “In Stock” filter on collection pages.
Only available products loaded — no extra filtering, no dead ends.
The result?
A 17.3% lift in conversion rate.

During high traffic weeks, seeing sold-out items frustrates and adds friction.
We showed only what was in stock so that ready-to-buy visitors could act fast.
