This 2020 year even my google traffic reduced by 80%. On my blog SQLwithManoj.com I used to get decent 3k-4k hits every day for last 4-5 years. But since Jan 2020 hits got reduced below 1k. And when I checked google webmaster I couldn't see my blog meta entry. Don't know how it got removed from there. Now since I've added it back the hits are still at around 1k, and this has cased good revenue loss for me too.
