A few WordPress speed fixes that actually made a measurable difference for me

I've been optimizing WordPress sites for a while (mostly WooCommerce and Elementor builds) and wanted to share a few things that consistently moved the needle on load times, in case it helps someone else:

1. Lazy-loading offscreen images plus converting to WebP cut LCP noticeably on image-heavy pages.

2. Disabling unused Elementor widgets/features from the settings panel (not just plugins) trimmed a surprising amount of JS.

3. A good object cache (Redis if your host supports it) made a bigger difference than switching page cache plugins ever did.

4. Auditing render-blocking fonts, self-hosting Google Fonts instead of loading from Google's CDN, helped with both speed and a bit of privacy compliance.

Curious what's worked for others, especially on WooCommerce stores with a lot of product images. Any tools you'd recommend for ongoing monitoring besides PageSpeed Insights and GTmetrix?
