Cache External Scripts vs Speedora Total Website Speed Optimization

Often when trying to optimize the Google Pagespeed score, there is one script which still causing the ‘Leverage browser caching’ rule popping up: Google’s own gtag.js and/or analytics.js file… With this plugin you will be able to cache this file on your local server and enable browser caching for longer than 2 hours. The plugin will check every day if there is a newer version of the file to keep the cache up to date.

Speedora is a free, all-in-one speed plugin. It caches pages, minifies HTML/CSS/JS, lazy-loads media, converts images to WebP, and removes unused WordPress baggage. Settings are grouped by feature, and child options stay locked until their parent is enabled. Do not run Speedora page cache together with another page-cache plugin (WP Super Cache, W3 Total Cache, LiteSpeed Cache, and similar). Use one page cache at a time.
