Front-End Optimization

Front-End Optimization (FEO) provides a suite of website performance enhancements that accelerate page rendering and reduce download times. By organizing your web resources into content groups, you can fine-tune which optimization methods to use on what types of content.


FEO is being decommissioned in June 2023

It'll be functionally decommissioned, which means:

  • FEO features set in your Ion property will no longer apply.
  • The FEO API will no longer function.
  • Nearly all of the functionality in the Front-End Optimization Configuration tool will be removed. You'll still be able to access it in ‚ÄčAkamai Control Center‚Äč, but only to review your FEO configuration metadata. The tool will be fully decommissioned in August 2023.

Talk to your ‚ÄčAkamai‚Äč account team if you need help migrating off of FEO.

How to set it up

FEO is unique to Ion and you need to add its specific behavior to your Ion property to enable it. However, FEO has its own configurations and you create one using FEO’s Configuration Manager.

Get your FEO configuration metadata

With decommissioning coming soon, you can get the metadata used to define your FEO configuration. You can potentially review it with your ‚ÄčAkamai‚Äč account team to see if you can apply it using other services in your Ion property.

  1. If necessary, log in to ‚ÄčControl Center‚Äč.

  2. Use the drop-down in the top right to select the ‚ÄčControl Center‚Äč account you used to create your Ion property.

  3. Go to ‚ėį > CDN > Properties.

  4. Enter the name of your property in the Filter by Property or Hostname field.

  5. Click the Property Name to open it.

  6. Select Front-End Optimization from the Related apps menu.

  1. Find your configuration in the table and select ACTIONS (...) > View Metadata.

Known issues


Adaptive Acceleration

Overall compatibility

If you're using FEO and want to apply Adaptive Acceleration, you can only use these features in FEO:

  • On-Demand Image Loading
  • Asynchronous JavaScript
  • Critical CSS

FEO and Brotli Compression

You can optionally add this advanced form of compression with Adaptive Acceleration. If you're using any aspect of FEO, this compression may not be applied to a request. If this incompatibility is discovered, gzip or uncompressed resources are served instead.

Image and Video Manager

These FEO optimizations are not compatible with Image and Video Manager:

  • Optimize Images
  • Optimize CSS: Image Compression
  • Optimize CSS: Use Web Resolution
