 URL Metrics have a “freshness TTL” after which they will be stale and the JavaScript will be served again to start gathering metrics again to ensure that the right elements continue to get their loading prioritized. When a URL Metrics custom post type hasn't been touched in a while, it is automatically garbage-collected.
 
-👉 **Note:** This plugin optimizes pages for actual visitors, and it depends on visitors to optimize pages (since URL Metrics need to be collected). As such, you won't see optimizations applied immediately after activating the plugin (and dependent plugin(s)). And since administrator users are not normal visitors typically, optimizations are not applied for admins by default (but this can be overridden with the `od_can_optimize_response` filter below). URL Metrics are not collected for administrators because it is likely that additional elements will be present on the page which are not also shown to non-administrators, meaning the URL Metrics could not reliably be reused between them.
