Q:    I created a new site and used the ITP section for the first time. I added one of the premade static templates and added a product to it.  When I published the site, I could not find the page with that product anywhere.
How does this function work?

 A:    Unless you use the %ITP% token in your static template, you wouldn't have a link to the internal target page.
TKP generates an ITP for every static site, whether you link to it or not.
On the Token Matrix, ITP is defined, so even if you didn't use the %ITP% token in your static template, you can still review the ITP which was published.
