Is it possible to achieve a perfect 100 score on Google PageSpeed Insights for WordPress?

Yes, it is technically possible to achieve a perfect 100 score on Google PageSpeed Insights for WordPress. To achieve a perfect 100 score, you’d need a lightweight and well-coded theme, limiting the number of plugins, compressing and resizing images before upload, leveraging browser caching and GZIP compression. It also means optimizing your database regularly, minimizing CSS and JavaScript files, using lazy loading for images and videos, and choosing a high-performance hosting provider with the latest PHP version and adding a Content Delivery Network (CDN). However, achieving that score may not be the most practical goal. You should also look at Core Web Vitals for a full picture on your website UX. A PageSpeed score of 90+ is realistic and effective.
