I like that it is easy to use with my social media accounts, as well as website links for campaigns/advertising etc; It's very user friendly! There are many different features you can access in order be able do things such advertising (adsense), tracking your data from analytics or reporting back what worked best during certain time periods of one year ago..etc As far as price goes - there isn't much difference between this product compared other paid services out here at least right now.- However if their prices were more competitive then perhaps we'd have less competition within our own market niche? We've been using them since they started up so not sure how long but would say about 1+ years maybe 2+.
The main benefit has come when doing SEO work which saves us alot money because its all done through an account manager who knows exactly where keywords should go along side competitors websites too.
