A/B test: filters in plain sight on mobile category pages
If you show your two most-used filters, say size and price, as buttons above the mobile listing instead of inside a panel, then more people will reach a product page, because opening a panel on a phone is a step many people never take.

Why it might work
On desktop the filters sit on the left where everyone sees them. On mobile they hide behind a "Filter" button that opens a panel with fifteen options. Someone looking for size 10 jeans has to open it, find the size, apply and close. Many would rather scroll and see what turns up, and after the third item that isn't in their size they leave.
Two visible buttons, "Size" and "Price", cut that path down to one tap. The other filters can stay in the panel.
How to set it up
In Bixlow you describe the change to the agent, it builds it on your site and launches it as an A/B test once you approve it.
- Check which filters your shoppers use most. If you don't know, in fashion it is usually size and price; elsewhere, brand or type.
- In the variant, show those two as large buttons above the listing that open their options directly.
- Keep a "More filters" button for the rest.
- Run it on mobile only, on category listings.
