Let’s just jump right into the options without any intro whatsoever!


Simply put, the start page of the plugin options panel. Not much to talk about this tab – it’s pretty self-explanatory.


This module caches your pages into static HTML files, greatly reducing database queries. It also helps browsers cache static assets more efficiently.

  • Enable/Disable Caching: Toggle the whole module without resetting the other settings in the tab.
  • Cache expiry time: By default, your cache files will go stale in 10 hours and will be regenerated automatically. Increase it here if you need to.
  • Separate mobile cache: If you’re using a plugin or theme that alters your page sources for mobile, turn this on. No need if you’re using a responsive theme.
  • Exclude URLs: Got any pages to exclude? Add their URLs here! (WooCommerce users: No need to add cart or checkout pages here, because they’re excluded by default.)
  • Cached query strings: If you have a plugin that generates different pages based on the query string, and you need to cache them separately, you can add the query string(s) into this textarea.
  • Connect to Cloudflare: Allows SBP to clear Cloudflare’s cache each time SBP’s cache is cleared (automatically or manually).
  • Cloudflare global API key: Without it, you can’t connect Cloudflare to your website. You can get it by following this tutorial.
  • Cloudflare email address: The email address you signed up for Cloudflare with.
  • Cloudflare zone ID: You can find your zone ID in the Overview tab on your Cloudflare panel.


This module helps you optimize the static assets in your pages by minifying HTML and CSS, lazy loading media (images, videos and iframes), deferring JavaScript, optimizing Google fonts and preloading any asset you want.

  • Minify HTML: Kind of explains itself, right?
  • Optimize Google Fonts: Gathers all Google Fonts links into a single link, and adds display=swap at the end of that link. Oh and also preloads the link. Pretty cool way of loading Google fonts, we think.
  • Lazy load media: Defer loading of images by lazy loading them.
  • Lazy load exclusions: Exclude images from lazy loading by adding their URLs to this textarea. PRO TIP: You should exclude all images that are above the fold, using the option right below this.)
  • Optimize JavaScript: Defer all JS (including inline JS) or move them to footer using this setting. You can’t do both, because it’s kind of pointless. Deferring will give you better results but it’s more prone to errors.
  • JavaScript exclusions: Exclude JS files or inline JS from being optimized by adding their URLs to this textarea. If you paste whole blocks of inline JS here, you’ll probably break your site, so use with caution.
  • Inline all CSS: Self explanatory.
  • Minify all inlined CSS: Also self explanatory.
  • CSS exclusions: Exclude CSS files from being inlined by adding their URLs to this textarea.
  • Preload assets: Add full URLs of files to be preloaded using the <link rel=”preload …> tag.


This module has features for specific cases like CDN usage, localizing tracker scripts, adding custom JavaScript code and optimizations for some popular plugins.

  • Enable CDN: If you’re using a CDN, paste its domain here so asset URLs in your pages will be rewritten with the CDN domain.
  • Localize Google Analytics & Google Tag Manager: Loads the tracker scripts (analytics.js, gtag.js or gtm.js) from your server’s cache directory. The cached tracker scripts will be regenerated every day.
  • Custom code manager: Add custom scripts using this tool, and optimize them by delaying their load. This tool does NOT support file URLs! It’s only suitable for inline scripts (for now) and you should only paste what’s inside the <script> tag without using the opening & closing tags (they’ll be stripped anyway).
  • Jetpack: Dequeue the devicepx script:
  • WooCommerce: Disable cart fragments:
  • WooCommerce: Optimize non-WooCommerce pages:
  • WooCommerce: Disable password strength meter:


This module lets you tweak the WordPress core and your page sources by dequeueing core scripts/styles, decluttering , optimizing revisions and the Heartbeat API and so on.

  • Enable
  • Trim query strings:
  • Disable self pingbacks:
  • Dequeue emoji scripts:
  • Dequeue the post embed script:
  • Dequeue jQuery Migrate:
  • Dequeue Dashicons CSS:
  • Dequeue Gutenberg CSS:
  • Heartbeat settings:
  • Limit post revisions:
