Hey everyone,
A few weeks ago, we encouraged, via a Learning Center entry, with mentions in the newsletter, blog, a podcast and the forum, that refreshing older Hubs that had gotten search traffic before, but had seen that diminish, with meaningful additions of useful content, might help get a boost of Google love.
A suggestion was made by Marisa Wright for a column to let you know when a change was made to a Hub. We thought it was a good one, and it has now been rolled out. On your My Account stats page, you'll see the final column will tell you when a Hub was last edited. Keep in mind that any edit at all will refresh the date on this, even if you made small changes that are not necessarily meaningful enough to prompt a refresh in the eyes of search engines.
So, thanks for the suggestion, and we hope you find this feature useful in updating your Hubs!
