What is the best education resource for Local Map rankings

[helloworld]

Maps has always been bit of an addon for me. I would really like to read a solid resource of what needs to be done work wise to rank in 3 pack. I am an extremly quick learner aqnd can filter out filler text to get to the good stuff, which is my preference.

A colleague sent me a work report recently, which off the back of, looks like 2008 SEO. It includes:

• Citations
• Web 2.0
• Wikis
• Blog comments

They all point to the map. He has only recently started doing this with his provider for his client. I am not opposed to doing the work, but in organic this would eventually trigger an algorithmic penalty.

I have also been looking at these Stacks and managed to set one up myself for testing purposes.
