Core Web Vitals & Speed

Data-driven performance optimization focused on passing Core Web Vitals, reducing payload sizes, and increasing conversion rates.

Technical Execution

Core deliverables associated with this capability.

Core Web Vitals Auditing

Identifying the exact render-blocking scripts, large layout shifts (CLS), and slow paints (LCP) hurting your site.

Asset Optimization

Implementing next-gen image formats, lazy loading, and critical CSS generation.

Database Tuning

Cleaning bloated options tables, adding necessary indexes, and optimizing slow WooCommerce queries.

Third-Party Script Management

Delaying or offloading marketing tags (GTM, pixels) so they do not block the main thread.

Common Scenarios

Typical infrastructure and codebase challenges I resolve.

  • Google Search Console is flagging your site for "Poor URLs" due to LCP > 2.5s.
  • Your mobile site feels sluggish, leading to high bounce rates on ad campaigns.
  • You have installed caching plugins, but the site is still failing PageSpeed Insights.
  • Your database has grown to 5GB and backend queries are timing out.

Measurable Outcomes

  • Consistently passing Core Web Vitals scores for both mobile and desktop
  • Reduced server payload and bandwidth costs
  • A smoother, faster experience that directly supports SEO and paid ad ROI

Technical FAQ

Will optimizing speed break my design or tracking?

No. I carefully audit your critical CSS and JavaScript. Tracking scripts are deferred or delayed, not removed, ensuring your analytics remain accurate.

Do you guarantee a 100/100 score?

I guarantee passing real-world Core Web Vitals (the metric Google actually uses for ranking). Synthetic 100/100 scores are often impossible on sites with heavy marketing tracking and do not reflect actual user experience.
