A widespread tool for traffic analysis is SimilarWeb, owned by the Israeli SimilarGroup: upon entering the domain you will receive the most diverse data straight away. The tool reminds us a bit of Google Analytics with regard to the scope and data formatting. The way these analysis results are displayed is extremely helpful: for example, they show the temporal development of traffic and the various traffic channels, like social media, direct traffic, or e-mail. There is even a breakdown of the most relevant social media channels: you gain a lot of information about the online strategy of your competitors.
Targeted visitors have a specific goal in mind while normal visitors are browsing the web without having a particular objective. Targeted visitors are looking for a solution to their problem and they are visiting your website because they believe they can find the answer to their question, the product or service they want. In other words targeted traffic are those people that visit a website with the intention of performing an action.
Websites produce traffic rankings and statistics based on those people who access the sites while using their toolbars and other means of online measurements. The difficulty with this is that it does not look at the complete traffic picture for a site. Large sites usually hire the services of companies such as the Nielsen NetRatings or Quantcast, but their reports are available only by subscription.
