Can backlink spam penalties be algorithmic or are they just manual?
I had a drop after the last major update, I went from 8.5K to 5K organic visits. A guy told me he was going to upload my Ahrefs DR a month ago, but I didn’t know how he was going to do it, until I found out it was backlinks spam. I got checked and I don’t have any manual penalty. So most likely it was an algorithmic penalty. So I want to know if my decrease was due to what this person did to upload my DR cheating Ahrefs, or if my site simply fell in so many visits due to natural things. I have never had such a strong decline, I lost position in all articles.
