On landing pages where there are many ways to get there (email, multiple index pages), we want to funnel users back to a single index. We currently use a breadcrumb at the top to indicate the canonical parent–child relationship and take users to the source, but I think it would be more elegant to make the page heading for the page serve as a back link.
For example, a page containing a sale from a store might see users come from any of a number of sources: email about the sale, from an index of sales for the week, from the store page, the homepage, a sidebar. Regardless of how people arrived, we want to route them to the store page, so the layout might look like this:
« Store Name
Is this an elegant solution? Can you cite examples of this in the wild?
