I own a business and I advertise in Google adwords, Bing ads, Facebook and few other places. All these are paid ads. My question is this; Is it possible for me to build a system which can connect to all these services via API or any other way and pull data so I can have a central system which gives me a snapshot of all data I need such as traffic, conversions etc. I know this can be done via Google Analytics but I'm using URL method in my site to tag leads with its lead source and this is done by having custom URLS for every campaign. So after many testings I found out this method is not working with GA.
I don't want to login to individual accounts on a daily basis to check data (Traffic, conversions etc) so if anyone know if this can be done via a custom system (I can hire someone to do it) or any public softwares available which can do this? I know softwares like Moz can do similar things but they are not mainly targeted at paid search or paid ads.
Thanks a lot :)
