Merch: Widget Visibility
Control which pages your widgets appear on with Jetpack's Widget Visibility feature.
Activate widget visibility at: Jetpack > Settings > Activate Widget Visibility
To control visibility, expand the widget and click the Visibility button next to the Save button, and then, choose a set of visibility options.
For example, if you wanted the Top Products widget to only appear on the home page, choose "Show" from the first dropdown and then add the rule: "Page is Home".
You can also hide widgets based on the current page. For example, if you don't want the Recent Posts widget to appear on shop pages, choose "Hide" and add each shop page.
