Website Performance Checklist
A guide to optimize your website's speed and performance
The truth is, a good-looking website isn't always a high-performing one. Without a clear optimization strategy, even the most beautifully designed site can fall short of its potential.
Not seeing the results you expected from your website?
You've spent time, energy, and resources building a site that looks great. The content is live, the design is polished, and everything seems to be in place — but performance? Not quite.
Low traffic, high bounce rates, slow load times, weak conversions… sound familiar?
The truth is, a good-looking website isn't always a high-performing one. Without a clear optimization strategy, even the most beautifully designed site can fall short of its potential.
That's why we've created this comprehensive website optimization checklist — a practical guide to help you review, refine, and rework your site at every level:
- Improve page speed and loading times
- Optimize for search engine visibility
- Create a smooth, user-friendly experience
- Fix technical issues before they cost you conversions
- Understand what users actually want — and deliver it
Whether you're launching a new site or want to improve an existing one, this checklist will help you take a structured, results-oriented approach to web performance.
Better UX. Better SEO. Better results.
Let's get started.
1. Core Web Vitals
Google's Core Web Vitals are a set of specific factors that Google considers important in a webpage's overall user experience:
Largest Contentful Paint (LCP)
Measures loading performance. To provide a good user experience, LCP should occur within 2.5 seconds of when the page first starts loading.
First Input Delay (FID)
Measures interactivity. Pages should have a FID of 100 milliseconds or less.
Cumulative Layout Shift (CLS)
Measures visual stability. Pages should maintain a CLS of 0.1 or less.
