I am running a couple of sites, basically in the alternate healing, self help, and conspiracy theory niche. On of my sites got hammered by Fred on 09 March, and left me without any explanation what happended. I thought it was somehow ad related and altered the site layout, which made it even worse as the bounce rate spiked. Starting from 1st position, medium competition money keyword, 3.600 ms, got knocked down to 3nd by Fred, which means I lost half my traffic. Changing the page layout, brought my down on 4th position, losing another 25%. Then I figured out, by reading various different forums and sites, that it is a general site quality update, hitting various factors as thin content, duplicate content, off-topic pbn and sape. This is how to figure out what exactly hit you: - lost several positions in serp -> quality content issue - lost several pages or weird google dance -> not strictly niche related pbn - deindexed -> most likely sape As I just lost several positions, it was most likely a content issue. I deleted the tag pages of my wordpress page (duplicate content issue) and several thin content pages. Removed the pages in search console, waited one day. And I am back Nr. 1, baby.
