Limit Posts to a Single Category
Keeps every post in exactly one category: when several are ticked, only the most specific one is kept on save, which keeps URLs, breadcrumbs and archives tidy.

Log Pages That Run Too Many Database Queries
Records front-end URLs that run more database queries than a limit you set, with the query count and load time, and lists the worst offenders under Tools > Heavy Pages.
Manual hreflang Links for Translated Pages
Adds a box to the editor where you list the URLs of a page's translations; the matching hreflang tags (plus x-default) are printed in the page head, for multilingual sites that do not use a translation plugin.
Mapped Domain Column in the Network Sites List
Shows each site's public address next to its network address in Network Admin > Sites and flags sites whose Home and Site URLs do not match, a common domain-mapping mistake.
Never Cache Certain URLs in WP Rocket
Adds URL patterns that WP Rocket must never cache, such as account, quote or booking pages with personal content, without touching the plugin's settings screen.
Noindex URLs With Sorting and Filter Parameters
Adds noindex to pages opened with sorting or filter parameters (such as ?orderby= or ?filter_color=), so crawlers do not index endless variations of the same list.
Pretty Search URLs
Redirects ?s=term searches to /search/term/ when pretty permalinks are enabled, which gives cleaner, shareable URLs.
Put the Category in Custom Post Type URLs
Builds custom post type URLs with a taxonomy term, such as /books/fantasy/the-hobbit/, which reads better and groups content by section.
Redirect Old Date-Based Post URLs
After switching from /2019/05/post-name/ style permalinks to plain post names, sends visitors and search engines from the old dated addresses to the right posts.
Redirect URLs With Capital Letters to Lowercase
Permanently redirects addresses typed or linked with capital letters, such as /About-Us/, to their lowercase form, avoiding duplicate URLs and broken links.
Refresh Permalinks Automatically When Post Types Change
Rebuilds the rewrite rules once whenever a post type or taxonomy is added, removed or gets a new slug, so new URLs work without visiting Settings > Permalinks.
Remove /category/ From Category URLs
Shortens category links from example.com/category/news/ to example.com/news/ and redirects the old addresses there permanently.
Remove ?replytocom From Comment Reply Links
Stops comment reply links from creating ?replytocom= URLs that crawlers treat as duplicate pages, and redirects any such URL to the clean post address.
Remove Comment Feeds
Removes comment feed links from the page head and redirects comment feed URLs to the homepage, while keeping the post feeds.
Remove WPML hreflang Tags From Paginated and Filtered Pages
Stops WPML from printing hreflang tags on page 2+ of archives, search results and URLs with query strings, where the alternates often point at mismatched pages.
Remove a Post Type or Taxonomy Added by a Theme or Plugin
Unregisters post types or taxonomies you never use, such as a theme's "Portfolio" or "Projects", to tidy the admin menu and URLs.
Remove the Post Type Slug From URLs
Gives a custom post type short URLs like example.com/web-design/ instead of example.com/services/web-design/, as pages have.
Rename a Plugin's Post Type
Changes the name a theme or plugin gave its post type everywhere in the admin, for example "Projects" to "Case Studies", without touching URLs or content.
Serve Media and Static Files From a CDN Domain
Rewrites the URLs of your uploads, theme and plugin files to a CDN or pull-zone domain you set, so images, CSS and JavaScript are delivered from the CDN while pages are still served by your site.
Short /go/ Links for Affiliate and Partner URLs
Creates short links such as /go/amazon/ that redirect to long affiliate or partner URLs, so links in posts stay tidy and you can update a destination in one place.
Shorter Post Slugs Without Stop Words
Removes filler words such as "the", "and" or "how" from automatically created post slugs and caps their length, giving shorter, cleaner URLs.
Simple Redirect List
Redirects old URLs to new ones with a 301 status from a list you maintain in the snippet. Good for a handful of moved pages.
Stop Author URLs From Revealing Login Names
Gives new users an author URL slug based on their user ID instead of their login name, and adds a one-click fix under Users for existing accounts whose author URL shows their username.
Stop Changing "Wordpress" to "WordPress"
Disables the filter that silently rewrites the spelling of WordPress in titles, content and comments, which can break URLs or quoted text.
