Software and gamesWhich niche and yea many people are reporting this I guess in few days it should become normal
Have not been building backlinks for months for these 290% wow, are you sure it's not some sort of penalty rather than just an algo change?
Do the websites have similar backlink profiles or content?
I see no traffic update in Analytic from the past 6-7 hours.
So most probably that causes the issue you are reporting.
