Marilyn is very flexible in terms of bidding automation. You basically set the condition and the action it needs to take if that condition has been fulfilled. That functionality allows to execute the entire bidding strategy automatically and manage a high volume of campaigns. The reporting is also good - updated in real-time. Also there is a very useful feature to get report automatically by email.

Marilyn is a very intelliget piece of software, which offers a lot of the same features as the market heavy-weights, such as Marin and Kenshoo, but also adds its own flavour. The similar features include rules for automatic bid adjustment, support for the main advertising platforms - Google Adwords, Facebook ads etc and report scheduling. It also has an excellent integration with Yandex Direkt and it's own editor for Yandex ads. The most useful tools are cross-checking for negative keywords between campaigns, to make sure they don't compete with each other, UTM-tagging, showing recommended bids, based on the stats it collects and intelligent performance monitoring. Also it has an excellent CPA optimization tool, which can increase the CPA up to 20% without having to increase the campaign budget - very impressive!
