I got this infographic here where it's much bigger than what I was able to make it on my page. It explains simply how you can use simple tricks to get more out of your google searches.
They had embedding code on this page but it did not work when I tried to use it. So I had to capture, crop and save this infographic in parts. I hope you can find something useful in it and my thanks to HackCollege for trying to make it available for embedding.
