The user needs to go back to a safe start location of the site.
It has become a standard in webdesign, that the site’s logo is always linked to a safe start location for the user. Normally, this is the front page of the site, but it could also be the front page of a section in the site, or some other safe start location for the user.
This and others patterns are available and ready to use in this massive Wireframe Bundle. Suitable for a wide variety of projects: Website and landing pages, Ecommerce, Dashboard, Flowchart and iOS.
