Clean Up the Page Head
Removes rarely used tags from the page head: RSD, Windows Live Writer manifest, shortlink, adjacent post links and the REST API discovery link.
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.
Disable oEmbed Discovery and the Embed Script
Stops your site from acting as an oEmbed provider: removes the discovery links, the embed REST route and the wp-embed script. Embedding YouTube and similar services keeps working.
Keep Speculative Loading Away From Cart, Checkout and Account Pages
Tells WordPress's built-in speculative loading (prefetching pages on hover) to skip cart, checkout and account pages, which are personal, never cached and expensive to build, so hovering over their links no longer costs server time.
Prerender Links on Hover
Upgrades WordPress speculative loading (6.8+) from prefetch to prerender with moderate eagerness, so pages open almost instantly after a hover.
Remove Orphaned Term Relationships and Fix Term Counts
Run on demand to delete category and tag links that point to posts that no longer exist, and then recount how many posts each term has.
