If you go to Google Webmaster Tools and check out the search queries report, you might think that Google was able to show almost real time data in terms of search queries done related to your web site.
Google has changed the date range bar at the top right to be the current date. But if you look closely, you will notice that the charted data is still with a three or so day delay from the current date.
Here is a picture showing the date range at the top right being the current date and the chart showing March 31st data, which was a few days ago.
Or maybe Google is rolling out up to the day search query data and I don't see it yet? Do you see today's search queries in Google Webmaster Tools.
