Forcing Lowercase URLs in Optimizely CMS During Auto-Translation
Community developer Stuart Greig outlined how to resolve URL segment issues in Optimizely CMS 12, such as incorrect casing and punctuation during LanguageManager auto-translation. The solution requires implementing a custom IUrlSegmentGenerator and event-based tracking to enforce lowercase URLs.

Fixing “Published By” After OKTA SSO in Optimizely CMS
Community member Sanjay Katiyar shared a solution for Optimizely CMS where enabling Okta SSO resulted in technical IDs displaying in the "Published By" field instead of user names. The article outlines a custom C# `PublishedByTransform` that resolves these IDs to readable emails or names, enabling developers to restore clear author attribution while maintaining SSO security.
Prove what your experimentation program is worth with Holdouts
Community member Sarahs Blog shared insights on utilizing Holdout groups in Optimizely Feature Experimentation to validate the net lift of an entire program rather than individual tests. This approach reserves a percentage of traffic as a global control group, allowing developers to configure a 1-5% holdout via the Flags > Holdouts tab for better ROI measurement. It is particularly useful for mature programs running concurrent experiments where individual test metrics no longer provide a clear baseline.
How to Disable automatic indexing in Optimizely Search & Navigation
Community member gulla.net shared a guide on Optimizely World Blogs explaining how to temporarily disable automatic event-based indexing in Optimizely Search & Navigation.
