Without seeing how your widget is setup, I am going to guess it is setup to just show up on the shop pages (I’m guessing you’re talking about the category pages).
Assuming this was done through the widget, go back to the widget’s configuration page:
CMS->Widgets-> Select your widget.
Near the bottom of the first page, find the Layout Updates section.
Now, lets assume you want this to show on all pages that use that 2 columns left template. Change the Page* value to: “All Two-Column Layout Pages (Left Column)”
It should now show on all of your 2 columns left template pages. This can be fine tuned if you’re trying to get it to show on a more specific basis.
