I like that it is easy to use for both clients & SEOs alike! It's also very intuitive which makes creating campaigns super fast without having any training or knowledge required from you as an user (which helps with retention!).
There are some things we'd love in general though - such as being able to edit campaign names once they've been created instead just changing them each time there needs adjusting- this would be great if done automatically rather than manually!! Also sometimes when editing tags/keywords etc., its not always clear what changes have already taken place even after saving so manual intervention can still happen occasionally too :) We're using Mozlocal primarily at present but will continue exploring other A9 features over coming months / years including paid advertising through Google AdWords via their integration into our account dashboard where users create ads directly within mozlocal itself.
