It's already plenty visible. If users want help with something, they'll click help. That will then bring them to a few options that might be useful to them. If they don't want help, then they're not going to click it. Without additional guidance somewhere, adding "Help Center" to the top bar will do absolutely nothing in the long run. They're not going to know they need to visit it and look at specific things in order to participate constructively.
This reminds me of when I worked at the grocery store and was in charge of the self service machines. The machines had a button in the top right corner. It said "help" and had a little question mark next to it, but, it wasn't actually a help menu. What the button actually did was called an attendant to come assist you. Management wondered why no one ever hit the button, as customers would instead look around and try to flag down the attendant instead of using the button that would notify and summon them.
After observing customers' actions, I finally started asking a few that would flag me down the old-fashioned way. One provided me with an amazing response. He stated he didn't want to hit help because he assumed it meant instructions, and didn't want to deal with the grocery store equivalent of the annoying paper clip. If the button had been more straight-forward with its intentions and said something like "Call Attendant" then he would have used it. (Sad ending: management completely ignored my report and made no changes whatsoever.)
So why did I tell this story? Well because we're kind of in a similar boat. But unfortunately we’re not in a position where we can just change the name of the link because our help center contains both:
- information that just answers everyday questions for problems users encounter, but has no immediate importance.
- information that is vital to understanding the proper use of our site, and should be looked at.
We want users to see the information from the second point right away, and we attempt to send them there in several ways via the tour, when they're first asking a question, and other side-bar guidance. But linking to the entire help center in the top bar just brings users back to the "well I don't have a question right now, so I'm not going to look at it right now" mindset. They don't know there's important stuff in there just from a vague link that... looks like it's probably going to be the same as the link a couple items further down the line.
We've been working on making sure we find all the pain points of being a new user and giving them more in-your-face at-the-last-moment information on how to ask their questions, because that’s where this information actually needs to exist. The help center will get the same amount of visibility whether it’s directly in the top bar or in a help sub-menu, but we can increase the visibility of specific, more important pages within it by targeting users with those links where it will have the greatest impact. Those are the places we need to focus our efforts, and we're happy to look at any suggestions for places where more just-in-time guidance is warranted.
