A Web “Page”

It’s not made of paper, you can’t touch it, you can’t bend it and it can change at any moment.  You can’t click on a piece of paper, you can’t ask a page a question, a page certainly won’t calculate anything for you or allow you to buy your groceries or sell your products.

So don’t think of your website as a web "page" or a collection of "pages” because that is exactly what they are not.
If you do then you will severely limit the possibilities and opportunities your site may bring you. By thinking in terms of "pages" you'll run the risk of thinking only about how your site looks rather than what it can actually do for you.

Paper pages work very differently to web "pages" and people interact differently with web "pages" than they do with paper pages. 
We probably need a new word... we definitely need a new way of thinking.

Finally, if you put your  web “pages” up on some webserver somewhere, satisfied with the fact that it looks nice and thus convinced that it will be a successful web presence for your business then you'll probably be severely disappointed by the results, and if not then you'll probably not know any different because the possibilities have passed you by.
