What’s New in Sitefinity CMS

Progress Sitefinity 15.4 introduces new AI capabilities designed to help teams improve SEO, LLM discoverability and deliver more relevant digital experiences. The release focuses on structuring content for AI discovery, bringing built-in AI agents to editors and marketers and providing tools for hyper-personalized digital experiences.

AI-Friendly Structured Content

Make your content readable by search engines and AI assistants

Sitefinity CMS automatically adds Schema.org JSON-LD structured data using existing fields, taxonomies and relationships, with no manual setup required.

This structured layer gives search engines and AI systems the context needed to interpret and surface content across search results and AI assistants.

For example, a page on a financial services website about credit offerings can include details such as fees, eligibility criteria and product type. When a user asks an AI assistant a question like “What credit options are available for small businesses?”, that context helps deliver accurate and relevant answers.

Dynamically Generated Experiences

Turn visitor intent into action

Dynamically Generated Experiences (DGE) combine visitor intent with profile and behavioral data from Progress Sitefinity Insight. This context allows Sitefinity CMS to adapt experiences based on who the visitor is and what they are looking for.

Instead of showing the same content to everyone, pages, messaging and answers adjust to match individual needs and context, including tailored FAQs, relevant product and service highlights and personalized CTAs.

For example, a returning visitor who previously explored business lending may see tailored FAQs, relevant credit options and next steps to apply. A first-time visitor researching financial services may see an overview of available offerings, guidance on choosing the right solution and key benefits.

Intent and identity work together to create experiences that feel more relevant and intuitive.

DGE Intent Grid

See how AI-generated experiences are created

The DGE Intent Grid gives teams visibility into how dynamically generated experiences behave. It displays captured visitor intent alongside the generated AI output in a structured interface.

Marketing and editorial teams can review which visitor segments triggered specific responses and how personalization decisions were made.

This is especially valuable in regulated industries that require compliance, transparency and traceability, helping organizations monitor AI behavior, refine personalization strategies and maintain oversight across AI-driven experiences.

Brand Agent

Keep your brand voice consistent across teams

The Brand Agent is an AI assistant built directly into the Sitefinity editor. It reviews content while it is being written and suggests improvements aligned with your brand guidelines.

Authors receive recommendations on tone, wording and messaging in real time. This reduces lengthy review cycles and helps teams produce content that stays aligned with brand standards.

For example, if brand guidelines call for a technical but accessible tone, the Brand Agent may recommend simplifying complex language while preserving the message.

Teams can maintain consistency across regions, authors and departments without slowing down content production.

SEO Agent

Optimize content for SEO directly inside the editor

The SEO Agent provides automated recommendations directly within the Sitefinity editor, suggesting improvements for titles, meta descriptions, alt text, canonical URLs and other metadata.

Editors receive actionable guidance without relying on external tools, with suggestions aligned to how people search. Whether creating content about financial services such as credit offerings or writing about manufacturing capabilities and processes, it helps improve visibility for relevant, high-intent queries.

The result is stronger performance across both search engines and AI discovery platforms.

Sitefinity × PARAG Connector

Power AI search and assistants with trusted CMS content

The Sitefinity × PARAG Connector continuously synchronizes content, media and metadata with Progress Agentic RAG for indexing and retrieval, creating a reliable foundation for AI search experiences and conversational assistants.

Content updates flow automatically into the retrieval system, keeping AI-generated answers grounded in current and approved information.

This works especially well in sectors such as manufacturing or associations, where users rely on accurate, up-to-date information. When a technician looks for equipment documentation or a member searches for certification requirements, the assistant can retrieve trusted answers directly from indexed content.
