Autoptimize vs Resource Not Found Placeholder | Prevent redirections due to not foud resources

Autoptimize makes optimizing your site really easy. It can aggregate, minify and cache scripts and styles, injects CSS in the page head by default but can also inline critical CSS and defer the aggregated full CSS, moves and defers scripts to the footer and minifies HTML. You can optimize and lazy-load images (with support for WebP and AVIF formats), optimize Google Fonts, async non-aggregated JavaScript, remove WordPress core emoji cruft and more. As such it can improve your site’s performance even when already on HTTP/2! There is extensive API available to enable you to tailor Autoptimize to each and every site’s specific needs. If you think performance indeed is important, you should at least consider one of the many free page caching plugins (e.g. Speed Booster pack or KeyCDN’s Cache Enabler) to complement Autoptimize or even consider Autoptimize Pro which not only has page caching but also image optimization, CDN, critical CSS and more! Autoptimize Pro Autoptimize Pro is a premium Power-Up, adding image optimization, CDN, page caching, automatic critical CSS rules and extra “booster” options, all in one handy subscription to make your site even faster!!

No more 404 errors and redirections due to missing resources. When a resource is not found, the plugin will replace it with an empty resource. No settings are needed for this plugin. Just activate it, and it will replace all the missing resources with empty resources, preventing 404 errors and expensive redirections. Many themes call https://yoursite.com/favicon.ico instead of the final favicon URL. Believe it or not, when a resource like a favicon is not found, WordPress loads all the plugins, the theme, and the core, and then it does a redirection to the final favicon image. This means that before the redirection the PHP code of the entire WordPress ecosystem runs, and all the database queries take place. This is really expensive in terms of performance. You may have already seen some WordPress websites where the favicon needs a long time before being displayed or long waiting times for a not found resource. Well, this plugin prevents this kind of issue. In the case of the favicon, if it’s not found in the main directory, the plugin will not replace it with an empty icon, but it will send to the browser the final favicon image without any redirections. In all other cases, it will replace the missing resource with an empty resource. It works for any kind of resource, but the resources with extensions .txt and .xml to avoid issues with the files which are generated on the fly like robots.txt and the sitemaps.
