Frequently Asked Questions
Common questions about FlashSpeed – Speed Optimization & Performance Booster
No. FlashSpeed is designed to be safe and non-destructive. All optimizations can be toggled on/off individually, so you can test each feature and disable anything that causes issues. We recommend enabling features one at a time and testing your site after each change.
Results vary based on your current setup, but most users see 30-60% improvement in page load times. Sites with many unused assets (emojis, embeds, etc.) see the biggest gains. Use Google PageSpeed Insights before and after to measure your specific improvements.
FlashSpeed works great alongside caching plugins like WP Rocket, W3 Total Cache, or WP Super Cache. FlashSpeed removes unnecessary assets, while caching plugins optimize delivery. Together, they provide comprehensive performance optimization.
Yes! FlashSpeed is compatible with all WordPress themes and most plugins. It uses WordPress's built-in hooks and filters, so it plays nicely with other tools. If you experience any conflicts, simply disable the specific optimization causing the issue.
Absolutely! FlashSpeed is fully tested with WooCommerce and can significantly improve checkout page speed, which directly impacts conversion rates. Many WooCommerce store owners use FlashSpeed to boost sales.
The free version includes essential asset optimization and meta tag management—perfect for most sites. Pro adds advanced features like Instant Page preloading, local Google Analytics, security headers, custom code injection, and agency management tools. Compare features
FlashSpeed only disables assets that are typically unused. For example, WordPress emojis are rarely needed on business sites. However, if you use a feature (like embeds), don't disable it. Test each optimization to ensure your site functions as expected.
Yes! By reducing the number of assets loaded, FlashSpeed improves Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS)—the three Core Web Vitals metrics Google uses for ranking.
Yes! The free version can be used on unlimited sites. FlashSpeed Pro licenses are available for single sites, 5 sites, or unlimited sites depending on your plan.
Go to FlashSpeed > Assets and enable "Disable Google Fonts". This prevents Google Fonts from loading, which can save 100-300ms on page load time. Make sure your theme has fallback fonts defined in its CSS.
