Questions
Good to know
What algorithm does QSortby use to maximize conversion value?
There's no single black-box formula. You pick the ranking signal per collection — sales velocity, revenue, margin, conversion rate, trending momentum, selling-fast, repeat-purchase, engagement, rating or newest — and QSortby scores your catalog in real time, keeping in-stock products first. The part that answers "maximum conversion value": you can A/B-test any sort against your current order, and QSortby measures the funnel it drove (clicks → add-to-cart → influenced revenue, via last-touch attribution) and reports statistical significance — so the winning sort is the one the data proves, not a guess.
What can QSortby sort by?
10+ live signals: sales velocity, revenue (GMV), margin, conversion rate, trending momentum, selling-fast (velocity vs. remaining stock), repeat-purchase rate, engagement (clicks / CTR / dwell / add-to-cart), rating, or newest — over a rolling or fixed window you choose. Per-visitor "For You" ranking blends weighted signals per shopper. Or order any collection by hand.
How do I know it actually lifts sales?
QSortby runs an A/B test between the new sort and your current order, then attributes downstream orders (last-touch) to the feed a shopper interacted with — reporting click-through, add-to-cart and influenced revenue per variant with a significance verdict. You see the lift, you're not taking it on faith.
Do I need to edit my theme?
No. QSortby maintains standard Shopify collections — add them like any other. No custom code.
What happens when a product sells out?
It drops to the bottom automatically, and returns to its earned spot once restocked.
Is there a free trial?
Yes — 7 days, billed through Shopify's Billing API on your normal invoice.
