Clearly big advertisers have PPC managers manage and optimize their Adwords and Bing Ads campaigns and are being paid on salary. I however like to know that for affiliates, does the practice of outsourcing your entire campaign managements to remote third parties exist. This entails delegating the tasks of choosing the best converting affiliate programs for any given niche, build the necessary websites/landing pages, setting up campaigns, choosing keywords and writing ads, and finally optimizing conversions and ROIs - all done remotely by a third party. Obviously one of the biggest issue here is trust, since your PPC manager will have access to your backend for reporting and earnings. So I want to throw this out here and see if anyone has heard of this method and whether it is practical, since I see many big affiliates who are huge advertisers run campaigns across multiple niches - and have always been curious as to how they do it.
There are certain whitelabel PPC management companies you can use and not allow 3rd party access directly to bing or adwords account.
