- SEO Ranking: Google uses Page Experience metrics, which include site speed, to determine your rankings. A faster website equals better organic reach.
- Conversion Rates: Faster sites lead to better user experiences, increasing conversion rates. Amazon famously discovered that every 100ms slower their site was cost them 1% of sales.
- Performance Reviews: Speed tests give you important information like how the server is performing, if the images are too big, if there are any caching issues, and whether the code is written properly.
