Browser and CDN Caching Headers for Visitors
Sends Cache-Control headers on public pages for logged-out visitors, so a CDN or proxy can cache them for a few minutes.
Snippet Library
Performance snippets for WordPress
Snippets that make WordPress lighter and faster: remove emoji scripts and embeds, control the Heartbeat API, limit revisions and load scripts only where they are needed. For developers and site owners chasing better Core Web Vitals.
Browser and CDN Caching for Feeds and Sitemaps
Sends cache headers on RSS feeds and XML sitemaps so feed readers, crawlers and CDNs can reuse them for an hour instead of making WordPress rebuild them on every request.
Cache oEmbed Results Longer
Keeps embedded content like videos and social posts cached for 30 days instead of re-fetching it from the provider every day.
Site Health Check for Compression and Browser Caching
Adds a Site Health test that requests your homepage and one of your theme's stylesheets and reports whether text files are compressed (gzip or Brotli) and whether static files get long browser cache lifetimes.
