Correction
How did your websites measure up? Ask yourself the following questions to determine the successful implementation of those sustainability metrics:
- For page speed performance, a score of 90 and above signifies the most energy-efficient websites. Did the page speed performance of both website examples reach this score?
- Which suggestions do you think are easiest to implement for optimising the page speed performance of your website examples?
- Do you think there are any suggestions that are more difficult to implement than others?
- Are both of your website examples optimised for mobile phones? If not, which adaptations do you think can be implemented for adjusting the websites to a mobile phone?
- Do your website examples use a CDN?
