You are given a code snippet to add to your page's HTML; a portion of which is copied here:
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
So I copied and pasted the above — as is — to the window of the Blogger editor (for editing blog posts). The Blogger editor has two editing modes: Edit HTML — which is supposed to let you directly edit the page's HTML — and Compose — which is more like an MS Word interface to editing a blog post; one can easily bold, italicize, change font, create bullets, and so on in this mode (using buttons rather than specifying HTML markup tags). Then that editor transforms your entered text into HTML.
var gaJsHost = (("https:" == document.location.protocol)? "https://ssl." : "http://www."); <br/>
Another curiosity is whether I should create separate Analytics "profiles" for each different page of my blog. And whether visiting my blog homepage will cause the analytics tracking scripts (which are inserted within every individual blog post) to *all be executed*. That is, I added analytics tracking scripts to each individual blog post. And when you visit my blog, you automatically see all posts. So presumably, every time I get a visitor to my homepage, all N analytics scripts will execute (where N is the number of blog posts) and so it will seem as if I've had N * x visitors (where x is the number of people who visit lizstinson.blogspot.com).
