Every 100 ms of page load delay costs a typical e-commerce store roughly 1% in conversion rate. WordPress powers more than 40% of the web — but an unoptimized installation quietly drains revenue every single day.
At MaxiMoruM, we have spent 20+ years tuning WordPress sites for Ukrainian and international businesses. Here is what actually moves the needle.
Core Web Vitals matter for revenue, not just rankings
Google's Core Web Vitals — LCP, INP, and CLS — directly influence both search rankings and user behaviour. An LCP above 2.5 s means visitors leave before your product page fully loads. Unstable layout shifts (CLS) erode trust and trigger accidental clicks. These are engineering problems, not design problems.
What we optimize
Server-side caching
We configure full-page caching using WP Rocket or a custom Redis-backed layer. Static assets are served from a CDN. Slow database queries are profiled with EXPLAIN and rewritten with proper indexing — often cutting query time by 80%.
Image delivery
Images account for 50–70% of page weight on most WordPress stores. We convert uploads to WebP, implement native lazy loading, and serve responsive sizes via srcset. A 4 MB product gallery becomes a 400 KB one without visible quality loss.
Plugin audit
A typical WordPress site accumulates 30–50 plugins over its lifetime. We audit every plugin for performance impact, replace heavy general-purpose plugins with lightweight custom PHP code, and remove unused dependencies. Fewer plugins means a smaller attack surface and a faster Time to First Byte.
Hosting infrastructure
Shared hosting is a performance ceiling. We migrate to VPS or managed cloud infrastructure running PHP 8.3, OPcache enabled, and persistent Redis connections. The same WordPress codebase often loads 3–4× faster on proper infrastructure.
Typical results
After a full optimization engagement, our clients see:
- LCP drops from 5–8 s to under 2 s
- 15–25% lift in mobile conversion rate
- Improved organic search rankings within 60–90 days
