Does something like Google Stacking really work?

Hey! I read stuff about Google Stacking and Authority Stacking here all the time.
I actually checked some of the Example Pages that used the Google Stacking Method only to see the Google Pages not even Index.
Does Google Authority Stacking actually do anything for your Website and Ranking?
Or is it just a way for people to make easy money by creating Google Docs that link to each other?

Actually Curious about it.
I am not trying to throw shade on the Sellers that sell it here.

Imo it's a gimmick, like most other things. Invest your time in better link building opportunities, anything that's available for free on a public platform is not worth the time and effort.

I know that I’m over two years late, but I want to say that imo it is worth it. I was skeptical at first too, but I bought the course from my mentor (from whom I’ve learned previous valuable things) and doing his procedures 4 months in a row I can tell you that the results have stuck around. Of course you might think “4 months is not enough,” and yeah i agree. But not just mine, I’ve seen theirs and I’ve seen other people who have followed them for longer.

I can’t account for what you learn from the people you choose, but if you do it correctly, yes, it does work — at least for my niche, which isn’t super broad nor super duper competitive.
