What is the Best Header Bidding Solution?


We get emails daily from ad networks or people who say they are an ad network offering solutions to raise CPM's.  As a small publisher it is very difficult to understand what ad networks actually offer a competitive service to Google Ad Sense.

What is the best header bidding solution for a small publishers? Is it better to go with multiple ad networks or just one like Appnexus or Pubmatic?

Over the last 10 years I have watched our traffic increase steadily by 15%+ per year.  However, our advertising revenue from Google and Media.net has stayed fairly flat and not increased much at all.   Is this because Google is continually taking a bigger piece of the revenue share?

We have heard that header bidding is a solutions that can increase CPM's by 2x or 3x depending on the traffic.  Is this true for someone is a niche map crowdsourcing publishing space?

Please email me if you have a solutions or suggestions.
