Two words I live by are "Scale" and "Automation" ( in my book labor can be considered automating as well ). Scaling things is a rather simple concept. All it means is once you have a scalable system designed do it 10 fold. What is a scalable system? That means a system that's repeatable. So for example you find a nice pattern that works in ppc say for example you take 10 offers to test, build lists consistently the same way ( maybe that's by a keyword tool, scraping data, trends data... etc ) then making a landing page for each. I'm assuming you're new so you're doing this all by hand yourself. Well do that a bunch of times and you'll find patterns you follow again and again. That's where the automation comes in build scripts to do your keyword scraping and gather a team of people to build landing pages for you. Keep following the same pattern just automate more and more of it. The more you automate the more you can scale your operation which is free your time up to build other parts of your business. Hope that clears things up for you some. So one day you can run 100 test campaigns at a time looking for the nuggets.
