Huge traffic drop after technical works. Please Help!
The 17 of March our website had been unavailable for a day due to technical maintenance, the next day due to a multiplying error our server was overloaded, the issue was fixed within 2 days, but the traffic has dropped abruptly, it stays down for over 2 weeks already, we keep falling slowly and losing keywords everyday. Technically everything seems to be working fine now, no manual action, the site has good health and speed.
Please if you have experienced a similar issue advise on what should be done ASAP to restore Google's trust , the website has good DR of 40, the content of our store is rich, but now domains with much poorer content rate higher and us almost completely out of SERP.
Will the traffic restore gradually, how to speed it up? (at the beginning of March there was a spam attack with backlinks trying to advertise to us, Ahrefs saw it as spam, so I suppose Google should as well, but maybe the Google Spam Update on March 24-25 combined with previous tech works was the main cause?) Compared to the previous 28-day period we are down: total impressions from 3m to 750k, total clicks from 22k to 8k :(
Thanks!
