Freelancers tend to outperform agencies because the talent is in close contact with the client. That said, even highly skilled ppc freelancers are usually only highly focused on the technical aspects of Google Ads management and don't stray beyond this. This is great for maximizing their earnings but less than idea for the 80% of clients who need more than just technical Google Ads help.  

In general, Google Ads is the easy part. At least 80% of your success is predetermined by the strength of your business model, unique positioning in your market and presentation of your website . Almost no ppc freelancers can effectively help you with that and very few even try.

I've turned the agency pyramid upside down and placed the founder (me) right next to the client (you) as your single point of contact. This allows us to bring the full energetic weight of our entire organization into laser focus ensuring the highest levels of expertise, strategy and accountability get applied to your project. By design, this limits the number of clients Net Return can work with, so it's critical that each relationship be as successful as possible for us to prosper.

Also, I escape the short comings of the one man show free-lancer model by leveraging myself with a highly specialized and experienced team of optimizers who work under my close supervision. As as well as, a deep bench of specialists who can be flexibly engaged to solve more exotic one-off issues that pop up.
