Frequently Asked Questions
Common questions about SOptimizer – Critical CSS, WebP, Asset Manager & Bloat Remover
No. SOptimizer is built with safety as top priority. All optimization toggles are non-destructive and opt-in. Each setting includes descriptive safety labels, and you can easily exclude specific scripts, styles, or URLs if a third-party plugin requires special handling.
No! SOptimizer works on any WordPress website. Core features such as Page Caching, WebP conversion, Critical CSS, Asset Manager, Font Self-Hosting, and Database Cleanup work on every WordPress site. The WooCommerce section activates only when WooCommerce is installed and active.
WebP images are typically 25% to 35% smaller than comparable JPEG and PNG files at the same visual quality. Smaller image files drastically reduce page payload, lower server bandwidth usage, and speed up Largest Contentful Paint (LCP).
Critical CSS identifies the CSS rules required to render content in the user's initial screen (above the fold). The plugin generates this CSS directly in your browser, minifies it, and inlines it into the HTML head while deferring secondary stylesheets. This eliminates render-blocking CSS warnings in Google PageSpeed Insights.
No! Unlike other plugins that require costly API credits or send your layout data to third-party cloud servers, SOptimizer generates Critical CSS 100% locally inside your browser. Your data never leaves your server.
When browsers load fonts directly from Google's servers (fonts.googleapis.com), visitor IP addresses are transmitted to Google. By downloading font files to your local server and rewriting stylesheet links, SOptimizer eliminates external requests, ensuring full GDPR compliance and faster local delivery.
By default, WooCommerce triggers an AJAX request (wc-cart-fragments) on every single page load to update the mini-cart count. On busy sites or non-eCommerce pages (like blog posts), this causes severe server load and slow Time to First Byte (TTFB). SOptimizer disables this request on non-shop pages while keeping the cart functional where needed.
Yes! SOptimizer works seamlessly with all major CDNs including Cloudflare, BunnyCDN, Fastly, and KeyCDN. If you use Cloudflare, upgrading to SOptimizer Pro allows you to connect the Cloudflare API to purge edge cache and manage DNS/cache settings right from WordPress.
In the JavaScript settings tab, simply enter the script handle or a URL keyword (e.g., jquery-core or custom-tracker.js) into the Exclusion list. The plugin will skip deferral for those specific scripts.
SOptimizer automatically purges relevant cached pages when you publish, edit, or delete posts, pages, or products. You can also manually purge the entire cache at any time using the Purge Cache button on the Optimize Dashboard or WordPress admin toolbar.
