While Parse.ly Dash provides services for bloggers and content producers, KISSmetrics excels with e-commerce sites that need to optimize their conversion funnels (the pathways customers take through a site to the checkout screen). It specializes in consumer behavior, tracking viewer activity over multiple sessions on your site and alerting you to holes in the funnel that could be making your site less efficient and costing you sales.
One of KISSmetrics' signature features is the Path Report, which tells you the specific routes customers tend to use on your site. That knowledge will give you insights on how to optimize your site to plug up the "leaks" where people tend to drop out. Then you can make other adjustments so the common pathways are more easily accessible. Once you do that, the orders will start rolling in ... until something changes and you have to revamp the site all over again. But at least with KISSmetrics you can stay one step ahead of the game.
