Definition
A content delivery network (CDN) is a network of servers that delivers website files from locations closer to the user, improving load speed and reliability.
Key Takeaways
- A CDN can improve page speed, especially for images and global traffic.
- Faster pages reduce drop-off on mobile and can improve conversion rates.
- CDNs need proper configuration to avoid caching issues and tracking conflicts.
Why It Matters for Treatment and Behavioral Health
People seeking help often use mobile devices. Slow pages increase abandonment and reduce calls and form completions.
Treatment Lens: What to Prioritize
Speed up program pages, location pages, and admissions pages. Ensure phone buttons and forms load correctly and remain tappable.
Implementation Notes
Set caching rules carefully, compress images, and test after changes. Confirm that tracking scripts and dynamic elements still work as expected.
Common Mistakes
- Enabling aggressive caching that breaks forms or dynamic phone number insertion.
- Assuming a CDN fixes a heavy, poorly built page.
- Not testing page performance on real mobile devices after changes.
