How I Built a Website Audit Tool That Found 50+ Performance Issues My Client's "Fast" Site
A website audit revealed over 50 performance issues on a client's site that was previously deemed 'fast.' The audit identified critical problems such as third-party script bloat and image optimization gaps that standard tools like Lighthouse overlooked. As a result, the client's mobile score improved significantly after implementing the recommended fixes.
- ▪The client's site had a Lighthouse score of 72 but was reported to feel slow.
- ▪The audit uncovered 53 performance and SEO issues, including critical script loading problems and image srcset gaps.
- ▪After implementing the top fixes, the client's mobile score increased from 72 to 94.
