Unlike some of the other SEO tools with reporting features, Megalytic is strictly a Google Analytics reporting tool. It is excellent at doing what it is designed to do. You can create comprehensive reports just by using the built-in templates. There are plenty of options to customize these reports, add widgets and massage the data anyway you want to. The real power however is in some of the KPI widgets. You can save custom reports as templates to reuse and these can automatically update by using rolling date ranges. This is a huge time saver. The charts and graphs are visually impressive and are easy for non-technical people to quickly see trends and understand what is happening on their websites. It is easy to add your own expert insights and advice with the note widget. This is a very powerful feature if you want to impress your boss or client with your knowledge and expertise. You can generate your own branded reports and schedule them to automatically email in the future. Mark is extremely knowledgeable and he is very responsive to support requests.
