Onsite revenue engine

Most of your revenue is sitting in the moments you're not watching.

Sellza.ly reads shopper intent in real time — onsite overlays, cart recovery, and personalized upsells that fire at the exact moment they'll work, not a batch email three hours later.

Where Sellza.ly fits

Built for the site you actually have, not the enterprise demo

Most CRO platforms make you choose: enterprise power with a six-week onboarding, or a lightweight tool that fires the same popup at everyone and trains shoppers to ignore your site. Sellza.ly is built to do neither.

Sellza.ly Enterprise platforms Overlay-only tools
Time to first live overlay Under 15 minutes 4–8 week onboarding Same day, one message for everyone
Message targeting Behavior + intent, per visitor Segment rules, needs an IT ticket One popup, everyone sees it
Cart recovery Real-time, on-site + email Email only, next-day Not included
Design control Native to your theme Templated, looks bolted-on Templated, looks bolted-on

The platform

Three systems, one shopper journey

We optimize the entire shopper journey — from landing to checkout. Each system watches for a different moment in the visit and hands off to the next.

Onsite overlays

Show the right message to the right shopper — a shipping-threshold nudge, a low-stock flag, a first-order code — triggered by real behavior, not a fixed timer.

↑ Avg. 6.4% lift in add-to-cart rate

Intelligent cart recovery

We use targeted website overlays and smart remarketing to recover abandoned carts and increase AOV.

↑ 2.1× recovery rate vs. email alone

Dynamic upsells

Personalized bundle and upgrade offers at cart and post-purchase, ranked by what similar shoppers actually bought next.

↑ +14% average order value
