Google Analytics displays the number of people who visited your website, the length of time people spent on your website and how they interacted with your website. People that interact well with your website will receive a Low Bounce Rate, which is good. If people grow impatient and leave your website quickly, due to a poor web experience, you will receive a High Bounce Rate, which is bad.
You can analyze your website traffic stats by understanding who your audience is and how they behave on your website. This is vital to the success of your campaign. Remember, if people interact well with your website, you are more likely to increase customers and sales. If they interact badly with your website, you will be wasting money on your online marketing campaigns.
