# Convertica

> Turn visitors and AI agents into customers. Convertica is a conversion rate optimization (CRO) company, founded in 2017, with 2,000+ clients. Verticals served: eCommerce, lead generation, SaaS, affiliate, agencies (white label).

Three offers, each at a fixed price in US dollars: the free audit (the whole report, every finding with how to fix it) and two rebuilds. Both rebuilds are paid through Stripe Checkout, either at the end of an audit report or straight from the buy buttons on convertica.org with no audit first (Convertica then runs the audit). After the order, the audit app runs a short setup, an order signed online, a job page where changes to words or offers wait for the buyer's OK, and a fresh audit of the page with before and after scores once every fix is live. A retainer or ongoing consulting is available on some bespoke campaigns, quoted one by one as a bespoke proposal.
