What was new in 2016 and still is

Shortly after I wrote the previous, then came AMP. AMP stands for Accelerated Mobile Pages and emphasis is being placed on websites being Mobile "FAST" loading.

Thanks Holger...you made some really important points in your OP.

For those that aren't aware, AMP is Google's resource for creating fast mobile pages. It uses HTML and some other coding to make pages load ASAP. When you design things like Google Stories you will use AMP. There are WYSIWYG AMP creators and you can also dig directly into the code. Again, it's basically HTML.

Here's a thread that digs into Google Web Stories (which use AMP):
