Block Fake Googlebot Visits
Checks visitors that claim to be Googlebot with a reverse DNS lookup and blocks the impostors, which are usually scrapers or vulnerability scanners.
Snippet Library
WordPress code snippets, ready to use
3,040 free snippets from the WPIDE team and the community. Copy the code, or add any snippet to your site in one click with WPIDE.
Browser and CDN Caching for Feeds and Sitemaps
Sends cache headers on RSS feeds and XML sitemaps so feed readers, crawlers and CDNs can reuse them for an hour instead of making WordPress rebuild them on every request.
Cache-Busting Versions Based on File Changes
Replaces the version number on your theme's and plugins' CSS and JavaScript URLs with the file's last-modified time, so browsers and CDNs cache files for a long time but always fetch a fresh copy right after you change one.
Disable the Emoji Script and Styles
Removes the emoji detection script, inline styles and DNS prefetch that WordPress adds to every page. Browsers still display emoji natively.
Preload Header for Your Theme Stylesheet
Sends an HTTP Link preload header for your theme's main stylesheet, so browsers, and CDNs that support Early Hints, start downloading the CSS before the HTML has even arrived.
Stop Browsers Prefetching DNS for Links on Your Pages
Sends the X-DNS-Prefetch-Control header to tell browsers not to look up the domains of every link on your pages in advance, so visitors' DNS providers do not learn which sites you link to before they click.
Subresource Integrity for Scripts and Styles From CDNs
Adds integrity and crossorigin attributes to the CDN-hosted scripts and stylesheets you list, so browsers refuse to run them if the CDN copy is ever tampered with.
