As announced by the Google Employee John Mueller that the Search Engine Giant is going to advice the Webmasters from the world who are seeking Onsite advice by offering “website reviews” on 18-11-2013 (Monday) (Timeline for the same would be as per Google's Working Hours!!!)
18 November - Google Site Review Day
So what are we all waiting for ? but we need to keep few sort of things in mind while taking an advantage of the offering. For that One must add their website to be reviewed into the Google Moderator Page; That's it rest is up to Google; if Google wants it to be reviewed online live or if Google has got some spare of time they will review it Live at 10am EDT November 18th "by Google+ hangouts".
If you wanna take up the chance to be up and reviewed live by Google just get yourself on the Google+ Hangout and add the event to the calendar and await for Google+ to launch it on the Air.
As per the sources it seems that the Site Review Event will be lead by John itself and mostly will last till an hour or so. However its not declared yet if few others from Google will be helping him for the review or not.
Per John -
For this hangout, we’ll review sites that are submitted via the moderator page and give a short comment on where you might want to focus your efforts, assuming there are any issues from Google’s point of view.:)
