The ability of this tool is that it can be used in different ways depending upon your requirements as well as budget plan you have chosen before using the product.
It has all features which are needed by any advertiser or marketeer who wants more control over his campaigns rather than relying only on Google's AdWords system. So far I haven't found anything negative about its use because everything seems perfect so far. We were able to get better results from our advertising campaign compared with old tools we had been working with previously.
