First I will start with some basic questions that every developer should ask before start developing an app.
- Do you use proper HTML tags?
- Do you really need those extra tags just for a line of text or for a background image?
- How fast it’s your page?
- Your CSS files are not too big?
- Have you minimized your JS/CSS files?
- The images you use aren’t too big and to many?
- Why so many http requests?
