Cheapest way to get thousands of backlinks per month
I am looking for a way to create thousands of backlinks per month all from related content to my main website. I am open to PBN creations and Spamdexing. Our niche is "Pets" and we are willing to spend $300/Mo on this project.
We have noticed that some of our competitors are using this strategy and we could use it too. We need advice, consultation, and a plan of action to acquire thousands of backlinks.
What would be your best method?
