> Google was injecting a large toolbar at the top of the snapshot encouraging users to get back to Google search results (a functionality already provided by the back button) I learned, through a series of usability tests my (former) startup ran amongst its users, that most non-tech people do not click the back button and get very confused if your pages don't have their own back/forward/close/menu navigation. We move…
i question the validity of your test and/or it's application in the current context. what I am hearing is "the average non-technical person incapable of using Google."
By non-technical I really meant they weren't developers; they were sales, marketing and management type people.
When asked, it simply didn't occur to most of them to simply press the back button.
Now, its not apples to apples, of course, and since this was in a web app where there may well have been a fear that pressing back would lose the page like you do in some (badly designed) single page applications, its possible that this skewed the results somewhat. Either way, we found that adding in-page navigation improved the workflow for almost everyone.
