Hi Marshall,
one resource I think is very valuable regardless of if someone is new or have been doing it for long time this is a great search engine optimization is this guide please do not think that I am giving you this because I think you are a beginner I know you are not. And I agree with you Google has made things kind of nuts in the last 3 to 5 years.

It is definitely the right place to start if you are just picking up after a couple years off.
Sincerely,
Thomas
