More and more visits from Google in my server log files are without exact referrer information, and have only "http://www.google.com", "http://www.google.com.au", etc. which doesn't allow to find out keyword and SERP page from which this visit was made.
Is anyone else experiencing this? Is there any official information from Google about this?
