Every second your WordPress store takes to load costs you customers. Google's Core Web Vitals — LCP, INP, and CLS — directly affect both search rankings and conversion rates. Here's how we fix them for real e-commerce businesses.
Why Core Web Vitals matter for revenue
A 1-second delay in page load reduces conversions by up to 7%. For a store turning over ₴1,000,000 per month, that's ₴70,000 in missed revenue — every month. Google also uses Core Web Vitals as a ranking signal, so poor scores push you down in search results and drive up your cost-per-click.
What we diagnose first
We audit three metrics before writing a single line of code:
- LCP (Largest Contentful Paint) — how fast your hero image or headline loads. Target: under 2.5 seconds.
- INP (Interaction to Next Paint) — how quickly the page responds to clicks and taps. Target: under 200ms.
- CLS (Cumulative Layout Shift) — whether elements jump around as the page loads. Target: under 0.1.
The WordPress optimization stack we deploy
- PHP 8.2+ — faster execution, lower memory use, better OPcache hit rates
- Redis object caching — removes redundant database queries on every page load
- WP Rocket or LiteSpeed Cache — page caching, CSS/JS minification, lazy image loading
- CDN integration (Cloudflare or BunnyCDN) — static assets served from edge nodes closest to your visitor
- WebP image conversion — 30–50% smaller file sizes with no visible quality loss
- Database cleanup and query optimization — removes bloat from post revisions, transients, and orphaned metadata
Results we've delivered
After full optimization, our WordPress clients typically see:
- LCP drop from 5–8s to under 2s
- INP below 100ms on product pages
- Organic traffic increase of 20–40% within 90 days
- Bounce rate reduction of 15–25%
WooCommerce-specific tuning
WooCommerce adds complexity: cart fragments, AJAX calls, and third-party plugins all add weight. We disable cart fragment polling for non-logged-in users, split plugin CSS/JS to load only on relevant pages, and implement persistent object caching for product queries.
