I have a good amount of knowledge in SEO already, but a lot of my 'tactics' I assume now are probably outdated. I am looking for some good books, videos etc on everything to do with SEO. Even basic topics like: - keyword research - on-page optimisation etc etc It's been too long so I just want to start from the bottom. I was looking at the Bulletproof local SEO course by Stephen Floyd, but I don't want to spend any money at the moment cause i've left my current job and don't wanna piss away money. Can anyone help me with some good, upto date resources for the whole SEO spectrum. cheers!
