Is Optimizely blocked by ad blockers?
Not enough data yet. Measurement for Optimizely is just getting started.
Optimizely runs A/B tests and feature experiments. When its CDN is blocked, experiment assignment and conversion tracking silently stop.

Daily Optimizely block rate measured over the last 90 days.
Not enough history yet to chart a trend.
How to reduce this
Partial fixSelf-host the Web Experimentation snippet through your own CDN so it loads from your domain. Note: experiment events still go to logx.optimizely.com unless you proxy that endpoint too.
Official Optimizely docs → blockrate's own first-party reporter already forwards events from your domain.
