SiteGuru is the only web application that combines web auditing with performance monitoring to keep site owners aware of what is happening with their websites. SiteGuru is fast, reliable and easy to use. It also has a built-in knowledge library that helps provide reliable answers to common questions. SiteGuru is the best tool for website owners who need to know how their website works, but don't have the time to do so.
From a personal point of view, as I run an SEO agency, it is an auditing software that saves me time, money and manpower. It has a dashboard where I can monitor the status of the website and the impact of the work done on my clients sites.

Very good product, I recommend it to novices and agencies alike.
