This week, Google is changing their GUI (graphical user interface).
The main changes are the addition of the left bar, but it's also targeting by default using the local place of the user.
For SEO, this represent an interesting challenge, most of the scripts and software became obsolete because of the new gui, but also because it gives more importance to fresh content, twitter and social media.
That should be combined with the new Adwords tool interface, that present a slightly different data from the old version.
