But they are a bit old. Im with
@BassTrackerBoats. I learn by pushing buttons and measuring what happens.
This is a big key though:
You need to understand an automation program like GSA, is just that, an automation program. Its not doing any magic secret that you can not do on your own manually.
so it will only do what you can do on your own, it just does it for you automatically. Far too often I find people that want to use an automation program/seo program (all SEO programs are is automation programs) and they want to push buttons and think that will get them what they want, but if you asked them to go do the same thing manually, they can't. Because they have no idea how to do it and thus don't know what the automation program is actually doing.
So I find it useful to work from the premise of "This is what I can already do manually and its good and works, so how can I find a program to automate it and how do I do it" Not the other way around.
So break down what GSA is doing and go do it manually a few times, and once you have a working understanding of what you can do manually and how GSA is then doing that for you, you can use it much better.
I am only able to master a program because I understand at a basic fundamental level every element that is happening, once you do that, its like tieing your shoe, you don't have to think all too much you just decide what you want and do it.
Lastly I would also say, you need to be self aware. Im 100% aware that Im able to succeed at automation programs because of my personality and mind set. It goes far beyond automation progams, even since I was a kid I always want to know how stuff works. Ive had people ask me if I was an engineer just because of how I Think. I suppose I could have been, but its not my thing.
If you don't understand how stuff works, but you can paint a picture like no one else, an automation program isn't the right thing for you. Hire someone to do it. I have painted exactly 1 picture in my life and it is no picasso and I followed step by step directions from an instructor. I couldn't even being to take a picture in my head and even think about what to do first to get it down on a canvas. I can follow "step 1, step 2 etc.." but I could never do free form.
But I can free form an SEO automation program like Michelangelo free formed the Sistine Chapel ceiling
you need to know who you are and play to your strengths.
