I think the new strategy from google has started. It is not giving any chance for Google Ranking tools and other Google Dance tools to get information from Google.
Randomly Google is asking for Human-Verification (captcha) to check whether the query is coming from a Human or a software.
The following is what Google is Displaying by redirecting google.com tyo sorry.google.com....
... but your query looks similar to automated requests from a computer virus or spyware application. To protect our users, we can't process your request right now.
We'll restore your access as quickly as possible, so try again soon. In the meantime, if you suspect that your computer or network has been infected, you might want to run a virus checker or spyware remover to make sure that your systems are free of viruses and other spurious software.
If you're continually receiving this error, you may be able to resolve the problem by deleting your Google cookie and revisiting Google. For browser-specific instructions, please consult your browser's online support center.
If your entire network is affected, more information is available in the Google Web Search Help Center.
We apologize for the inconvenience, and hope we'll see you again on Google.
I have noticed this from past 3 hours in India. Any more members to support this?
Google will make SEOs work more challenging with this by not giving search results to automated tools/softwares.
Guys be ready for Manual checking again on Google for ranking information.
