How fast should my site be?” How long do you wait for a web site to load? Not long I bet, waiting for something is frustrating and people do not like doing it. In a world where information is almost instant our patience has grown less and less and so speed is part of the usability of a website and so the faster a website the better the usability.
How fast is fast?
In Google’s Site Performance for Webmasters video, Miles V Design states that:
2 seconds is the threshold for e-commerce website acceptability. At Google, we aim for under a half second.”
Half a second is literally the blink of an eye. Google already considers page speed a ranking factor, meaning that sites that load faster would rank higher than similar sites that load slower.
