I like that they're constantly monitoring your site to make sure you get more traffic from search engines! They also have some great tools out there so once again it works well with other software/products we use at work aswell such as Google Analytics etc which is useful too because sometimes its hard tracking down problems or issues when using one platform only - not this time though thanks guys!! Nothing really but if i remember correctly our website was getting less views than expected in comparison compared to what google analytics shows us now after implementing them into all platforms.
