Curious if anyone has any documentation, YouTube videos, articles or even great examples of website layouts as it relates to customer flow and funneling them towards the Call-To-Action (CTA).

I have lots of sites that I think look good but am not sure if they are in line with what a marketing/advertising/site optimization team would say is good.

I'm assuming a well established site like Facebook can do things that a startup company wouldn't want to. So any links to proper page layouts for smaller sites would be good
