This is a slightly odd discussion.............we have allegedly, the highest earner in the business being given "advice" from others , who, presumably know much less about marketing.
The 60 second rule is out of date, due to modern technology, which is causing the attention span, to be reduced to just a few seconds.
To confirm this, you just have to think about the astonishing number of times, on here, when someone posts a comment, which is "skimmed" by many, who only get the gist of the message but often miss the detail.
I would not attempt to advise anyone on web design, as I know very little about it, however, we are talking about MARKETING whether on the web, or elsewhere.
So............if you're wishing to sell your product, or service, there is only one way to do it....you have to consider the absolute basics of human nature and that means, in the prospect's mind............WHAT'S IN IT FOR ME ?
You then have to tell them, what you can do for them, show them what you can do for them and tell them again, what you can do for THEM
