I like that it's very easy for me, as an individual user of this tool, to understand how my website is performing compared with other websites in terms of traffic sources (organic or paid). It also helps keep track of all analytics data from different tools such as Google Analytics so you can easily compare one against another without having multiple accounts open at once! Nothing really - just make sure your account has enough storage space available because there are quite some features included within these packages which require large amounts of disk drive usage. We use WhoIs Amung Us mainly to monitor our organic search performance but we've found out more about what keywords people have been searching using when they get directed towards us via searches made through third party platforms.
