WordPress Speed Optimization: A Complete Guide for Business Sites

Site speed affects Google rankings and conversion rates. A one-second delay can reduce conversions by 7%+. Here is how to optimize WordPress properly — not just install a cache plugin and hope.

Measure first

Baseline with PageSpeed Insights, GTmetrix, and WebPageTest. Track LCP, INP, and CLS — Google’s Core Web Vitals.

Hosting matters

Shared hosting struggles with WooCommerce. Consider Cloudways, Kinsta, SiteGround, or LiteSpeed hosts for serious business sites.

Caching layers

Page cache + object cache (Redis) + CDN (Cloudflare, BunnyCDN). Exclude dynamic WooCommerce pages from full-page cache.

Images and fonts

WebP/AVIF, lazy load below fold, limit font weights, self-host or use font-display: swap.

Database and plugins

Remove unused plugins, clean post revisions, disable wp-cron on low traffic and use system cron instead.
