description: 'Yieldify is a website personalization and conversion rate optimization (CRO) platform for ecommerce brands,
  founded in 2013 in London by Jay Radia and backed by investors including GV (Google Ventures). Its SaaS platform delivers
  targeted on-site messaging, customer-journey personalization, and A/B testing to lift conversion and revenue. Yieldify was
  acquired by Publicis Groupe in January 2023 and folded into Epsilon, where it is now sold as Epsilon Accelerate; yieldify.com
  redirects to the Epsilon Accelerate product page and the legal entity behind the platform is Zeus Enterprise Ltd, trading
  as Yieldify. Delivery is entirely client-side: a customer-specific JavaScript tag placed before the closing head tag (directly,
  or via Google Tag Manager, Tealium, Shopify theme.liquid or Recharge checkout) renders a documented library of on-site experience
  components — overlays, notifications, banners, sticky and embedded experiences, toasters, carousels, countdown timers, lead-capture
  forms — configured from the Yieldify Conversion Platform at convert.yieldify.com, with a typed dynamic-expression language
  for personalized copy and client-side yieldify_impression/click/close/form_submit events pushed into the customer''s own
  GA4 property. There is no public developer API: probing every Yieldify host on 2026-08-13 found no OpenAPI, GraphQL, MCP,
  A2A card, webhooks, SDK, CLI or developer portal, the status page at status.yieldify.com has been deactivated, and no pricing
  is published anywhere.'

  detail: Yieldify ships as a client-side JavaScript tag only — its 137-article Epsilon Accelerate help center covers campaign
    components, targeting and CSP allowlisting but contains no API, webhook or developer reference, and no OpenAPI/GraphQL/MCP/agent-card
    exists on any of its four hosts.
