How much does someone need to know about web development before he/she can use Page Speed?
We assume that webmasters who are interested in improving their site’s performance will probably have fairly advanced knowledge of web development techniques. Some Page Speed rules are based on basic principles of web development; others are based on more advanced features. It is helpful to have some knowledge of web hosting technologies, HTTP, JavaScript and CSS. However, extensive documentation is also provided, so anyone can follow Page Speed’s recommendations.
