Is the second visit always faster?<\/strong><\/p>\n\n\n\nNo. Cached files expire, and when you update your theme or plugins, the file names usually change, so the browser has to download them again. A hard refresh (Ctrl+Shift+R, or Cmd+Shift+R on Mac) also bypasses the cache on purpose. And if the visitor browses in private mode, everything is cleared when they close the window.<\/p>\n\n\n\n
Does browser caching improve my PageSpeed Insights score?<\/strong><\/p>\n\n\n\nNot the lab score directly, since that test measures a fresh page load. It can clear the “Serve static assets with an efficient cache policy” warning, while real visitors still benefit from caching on repeat visits.<\/p>\n\n\n\n
How long should static files stay cached?<\/strong><\/p>\n\n\n\nUp to a year is fine for versioned static files whose URL changes whenever the file changes. That way the browser can keep the old version for a long time without any risk of serving stale content. HTML usually needs a much shorter lifetime or regular revalidation.<\/p>\n\n\n\n
Does a CDN help first-time visitors, or only returning ones?<\/strong><\/p>\n\n\n\nIt helps both. Many first-time visitors still get a cache hit, because someone else nearby already requested the same file. If that edge server doesn’t have it yet, or its copy has expired, the request has to go back to your origin or to an upstream cache first.<\/p>\n\n\n\n
