The Issue of Performance
As I mentioned in the introduction, speed is a feature. You might be asked to make a simple website, but no one, ever, will tell you to make a slow website. Websites need to be fast. Performance is the key to success. Performance increases user satisfaction; it results in high conversion rates and higher revenue. Let me share some facts with you:
- Rebuilding Pinterest pages for performance increased conversion rates by 15% (https://www.hardkoded.com/ui-testing-with-puppeteer/pinterest-case).
- By reducing the response size of the JSON needed for displaying comments, Instagram saw increased impressions (https://www.hardkoded.com/ui-testing-with-puppeteer/instagram-case).
- Walmart saw a 1% increase in revenue for every 100 ms improvement in page load (https://www.hardkoded.com/ui-testing-with-puppeteer/walmart-case).
As you can see, performance puts money in your pocket.
