WooCommerce Performance Audit: Fix Your Slow Store
Slow WooCommerce stores lose customers and search rankings. Run a free performance audit in 30 seconds - identify hosting bottlenecks, plugin bloat, and the exact issues costing you sales.
What Our WooCommerce Audit Covers
Server & Hosting
TTFB measurement, server response analysis, caching detection, and hosting performance assessment.
Plugin & Script Impact
Every third-party script identified and measured - find which plugins are adding the most weight to your pages.
Core Web Vitals
LCP, CLS, FCP, and TTFB against Google's thresholds. See exactly where your store falls short.
Common WooCommerce Performance Issues
- 1Slow hosting - shared hosting with TTFB over 1 second makes everything else irrelevant
- 2No page caching - WooCommerce generates pages dynamically on every request without a caching plugin
- 3Plugin bloat - 30+ plugins with overlapping functionality and heavy JavaScript injection
- 4Database bloat - thousands of post revisions, transients, and orphaned metadata slowing queries
- 5Unoptimised images - large product images without compression, lazy loading, or WebP conversion
- 6Outdated PHP - running PHP 7.x instead of 8.2+ costs 20-30% in raw execution speed

Frequently Asked Questions
How do I audit my WooCommerce store performance?
Enter your WooCommerce store URL in the scanner above. PageDiag analyses your Core Web Vitals, server response time (TTFB), JavaScript and CSS payload, third-party scripts, and WooCommerce-specific performance factors. You get a detailed report with prioritised fixes in under 60 seconds.
Why is my WooCommerce store so slow?
The most common causes are: cheap shared hosting with slow server response times, too many plugins (especially poorly-coded ones), unoptimised database with bloated wp_options and post revisions, no caching layer, unoptimised images, and an outdated PHP version. WooCommerce stores are more vulnerable to hosting issues than hosted platforms like Shopify.
What is a good TTFB for WooCommerce?
Time to First Byte (TTFB) should be under 800ms, ideally under 400ms. If your WooCommerce TTFB is over 1 second, your hosting is the bottleneck - no amount of front-end optimisation will fix a slow server. PageDiag measures your TTFB and flags hosting issues.
Do WooCommerce plugins slow down my store?
Yes - but it depends on the plugin. Some plugins add minimal overhead, while others inject heavy JavaScript, make external API calls on every page load, or run expensive database queries. Common offenders include visual page builders, SEO plugins with excessive features, and poorly-coded analytics integrations. Quality matters more than quantity.
How much does WooCommerce hosting affect speed?
Hosting is the single biggest factor in WooCommerce performance. A store on £3/month shared hosting will typically have 2-4x slower TTFB than one on managed WordPress hosting. For WooCommerce specifically, look for hosts with PHP 8.2+, object caching (Redis/Memcached), and server-level page caching.
