I'm auditing a site. Their org traffic grew 90% in 2019. Found hockey stick growth in links around Feb 2019. Then a drop in traffic after the March update.
These links are on thin content domains that have different domain names but the same layout.
They look identical. Some of them 404.
I think the site owner bought these. Or the owner of the link farm just spammed the hell out of them.
I hear Google ignores spam links. But does anyone think these links could have caused the drop in the traffic?
Should I disavow?
