Hi I just see that i can not find any search volume on keywords like viagra, cialis in google adword keyword tools Why it is happening?? Can you anyone go here https://adwords.google.com/o/Target...956&__u=4441732266&__c=1885744956#search.none and search viagra and cialis and check the search volume. Few days before i can see the search volume there but now i can not see those. Can any one tell what is this going on in gooogle now???? Please reply its important for me. Thanks
