I started my career in SEO and moved into web Manager because it was just too tiring keeping up with Google. I think my last update that I could remember was called “Panda”. This is when they named their updates.
My current SEO strategy is super simple. Have the content you’re writing for relate as much as possible to the user intent. Give the user what they are looking for FAST and then crosslink, cross sell after. You will have a good page.
