This guide provides a comprehensive overview of how the editor works, what it supports, and how to maximize performance and discoverability using structured content.

The 3BL Editor is a structured, HTML-based publishing environment. Formatting is not decorative — it is a technical decision that affects how content is rendered, indexed, and distributed.

Character Limits

• Headline: 255 characters
• Subheadline: 255 characters
• Body: No limit
• Short teaser previews (email distribution): 280 characters

Supported HTML Elements

Content Sanitization & Unsupported Elements The editor automatically removes unsupported or unsafe elements, most commonly:

• Special characters, emojis, math symbols
• <div> (except for specific oEmbed use cases) 
• <span> 
• <video>
• <audio>  
• <iframe>

Before vs After: Enhanced Formatting Example The following example illustrates how structured formatting with multimedia improves clarity, rendering consistency, and semantic hierarchy – overall improving how readers interpret the story.

Rich Content & Performance Considerations Rich content is more than just visual enhancement, it affects rendering behavior, how information is consumed by search engines, accessibility, and consistency distributed across channels.

• Your headline should clearly communicate what the content is about in less than 60 characters.
• Use the description to add context about why this topic matters and why your organization is positioned to speak about it.
• Within the content, the first header (H1) should mirror your headline, using words that communicate authority or nod toward search intent where relevant (i.e., “how,” “why,” “answered,” “explained”).
• Secondary headers (H2, H3) help break up your content and transition from one topic to the next, which is more readable to robots than a long block of text.
• Keep each section modular, using short and self-contained sections with one clear idea to avoid long, blended paragraphs covering multiple topics.
• Add descriptive alt text to images to help visually impaired readers and AI systems interpret the visuals you use.

Today’s audiences make snap judgments — and corporate content is competing with everything else in their feed. The brands that earn attention are the ones that make it easy for people to connect, stay engaged, and take action. Why engaging content performs Engaging content:

• Keeps people reading longer
• Increases click-through and sharing
• Builds trust through clarity and transparency
• Makes complex topics easier to understand

What “engaging” really means (in practice) Engaging doesn’t mean flashy or loud. It means clear structure and purposeful formatting, strong narratives (the “why” behind the story), and visual reinforcement. That’s why we’ve upgraded our editor infrastructure to support richer multimedia content. This update is designed to give customers the creative flexibility to build more compelling stories — while ensuring reliable distribution across endpoints. Importantly, the upgrade is behind-the-scenes: published stories will look the same today along with the experience. But the foundation is now in place to support mixed media moving forward.

If you’re looking for ways to increase engagement and improve performance, this editor upgrade is just the beginning. We’ll continue expanding what customers can do with content in 2026. Reach out to your Customer Success Manager for multimedia best practices and enablement.

Over the past few weeks, we’ve rolled out a series of platform enhancements focused on one of the most fundamental aspects of effective distribution: knowing your audience.

These updates strengthen how we bring contact information together and interpret it across systems so your audience’s view is clearer and more unified.

What This Means For You We’re seeing 20-30% more enriched audience profiles, which means our AI classification system has been able to successfully fill in more missing details for better segmentation capabilities and more precise targeting for your campaigns. Our reporting displays the same data points as always, with richer professional details and top audience segments based on:

• Industry
• Department
• Job level
• Demographics

The improvements to our data processing across the board result in more complete profiles and accuracy of categorization—you’ll see more relevant professional categories and precise classifications that actually align with your targeting needs. Updated Reports & Dashboards All of your key reports have been updated to reflect these improvements:

• Six Month Summary – Now includes enhanced audience data
• Analytics/Insights – Reflects improved accuracy across all metrics
• Analytics/Audience – Shows more complete profile information

All recent audience data and backend reporting systems have been reprocessed and reflected in your reports and analytics.

This change means you no longer need to remember or reset a password to sign in. Here’s why we made this change:

Simply go to the login page, enter your email address, and click the one-time link we send you. This update is part of our broader commitment to streamlining workflows and strengthening security across the 3BL platform. Try Logging In with Magic Link — Brittany Partridge, Sr. Product Manager

As more audiences turn to AI assistants instead of traditional search engines, the way content is discovered is changing. Stories are no longer only surfaced through keywords — they’re increasingly being pulled directly into large language model (LLM) experiences like ChatGPT, Gemini, and others. That shift raises a big question for communicators: how visible is your content inside AI? What’s New: AI Crawler Traffic Reports We’ve released an update to our content analytics that helps you understand how LLMs interact with your content across two dimensions:

• Indexing visibility — see which models are pulling in your content (and which aren’t).
• AI impressions — measure how many times your content is surfaced inside AI-powered experiences via impressions and how many times a user has viewed the content via page views.

Together, these metrics provide the first window into your AI visibility footprint. Why It Matters This update lays the foundation for AIO (AI Optimization) — the next evolution of SEO. Just as organizations once optimized content for search engines, now is the time to understand how your stories appear inside generative AI experiences. By tracking where your content is indexed, how often it appears, and identifying gaps, you can strategically improve discoverability and authority in these new discovery channels. 3BL clients can explore their AI content tracking here.
