WordPress performance starts with measurement. Identify slow pages, heavy images, expensive queries, and scripts that block rendering.
High-impact actions
- Resize and compress images before uploading them.
- Enable a properly configured page cache.
- Remove unused plugins and limit third-party scripts.
- Load non-critical resources after the main content.
- Use maintained hosting and a supported PHP version.
Check after every change
Test the homepage, articles, forms, and mobile layouts. An optimization is successful only when it improves metrics without harming accessibility or functionality.
