The option of changing different ads in one interface! That's how I can use this tool for so many things; from simple advertising banners to complex landing pages design (for my business). Also it has been easy to upload images that will be used as "Banners". Sometimes it takes time when creating an ad because some tools do not allow me to save changes without having first delete all elements previously created. So keep working until success. It makes sense if you are using multiple websites/blogs etc., but what benefits does there actually offer? As usual, I'm trying out several options available online and hope something fits perfectly together with other web-based services such as SEO Analytics Pro - which also integrates quite well into its features.
