Key Findings
1. Why Performance Matters
Google uses Core Web Vitals as a ranking signal. Users expect pages to load in under 3 seconds. A slow site increases bounce rate and reduces conversions. NakedURL gives you a quick performance snapshot.
2. Key Metrics: TTFB and Page Size
TTFB (Time To First Byte) is the time it takes for your server to start responding. Under 200ms is excellent. Page size affects load time – smaller is better. NakedURL combines these into a performance grade (A, B, C, or D).
3. How to Improve Your Grade
If your grade is low, start by optimising images, enabling Gzip compression, and using a CDN. Move to faster hosting, and implement caching at both server and browser levels. NakedURL shows you your current grade so you can track improvements.
- Compress images and use modern formats (WebP)
- Enable Gzip/Brotli compression
- Use a content delivery network (CDN)
- Implement browser caching with Cache‑Control headers
- Reduce third‑party scripts and trackers
⚠️ The Problem
Slow websites lose visitors and rankings
- High TTFB – slow server response
- Large page size – slow to load
- Poor performance grade – below average

My TTFB is 300ms – is that bad?
