After loggin in to Google Analytics, clicking the "Show Visits (last 30 days)" button will show the number of visits and the percentage.
Normally the percentage is around + or - 5%, but the past few days I noticed it's above 100%.
The daily statistics are at normal and I don't see any spikes in visits.
At Google Analytics support page, it only says "Click Show Visits to see the total number of visits and the percent change in visits in the last 30 days."
Can anyone explain why is Google Analytics showing an abnormal boost for the percentage in visits for the past 30 days?
