Hi! I have an issue with my blog. After may core update I lost most of the keywords (about 90%) and my site doesn't show up in SERP anymore, I had 500 visits from google per day, now it is about 50 per day. The thing is, I wasn't deindexed, nor manual actions were implemented on my site by google (checked GSC), I checked pages and they all are in SERP (site:sitename.com). What should I do? I audited my site in semrush, there are no errors. What should I do? Please help. I am desperate as I really don't know what actions should I implement so my blog can reappear in SERP. Thank you.
