Community Q&A
How do I fix LCP issues on mobile?
Ensure your hero image is not lazy-loaded and add fetchpriority=“high” to the image element to prioritize its loading.
Should I use background images for hero sections?
No, background images are harder for browsers to prioritize. Use standard image blocks for content appearing above the fold.
Why is my site slow despite using optimization plugins?
Too many optimization plugins can conflict. Try removing redundant plugins and ensuring your caching settings are not fighting each other.
How do I handle Google Fonts for better LCP?
Preload your Google Fonts or any third-party fonts used in the LCP area to ensure they are available as soon as the browser needs them.
