There are a lot of questions from people like "I added a new PBN backlink and my rankings dropped, is that normal?" And the answers usually are "Yes, this is normal, wait some time and rankings will rise again." I don't know if I disagree with that, BUT ... What about when a person is constantly adding new backlinks? Like, add a link today, add a couple in a week, add a few a week later, and on and on. Wouldn't that site *ALWAYS* be jumping around in SERPs? Same for sites that aren't doing SEO, but are getting backlinks naturally. A popular site will be getting new backlinks all the time, forever. Wouldn't that site be jumping around in SERPs, forever?
