Is there Google update is going on or stop? Actually when search something in google always show new results in Google SERP..

There isn't any update rolling but something is impacting organic traffic very badly.

Possible March 10th Google Search Algorithm Update

I am seeing some oddities with rank reporting. For local based sites lots of rankings show WAY down, yet manual searches, checks using other software, and even Google Analytics data all appear perfectly normal.

At present there is no Google update going on.

Yes. At percent there is no update in google.
