Buy a high-authority 10-50 DA (domain authority) website off of Sedo.com, Godaddy auctions or Flippa.
What? How is it possible you ask?
1. Buy an expired, dropped domain with 10-50 DA. It turns out there are a lot of them expiring every day!
Here’s a cool free online tool to show you powerful domains that expire soon: domcop.com
2. Once you buy it, place it on a hosting, located in a Data Center different from what you use now.
3. Then there 2 ways:
2.1. Restore content from archive.org (you may have copyrighting issues) and then place a bunch of links to your website.
2.2. Place an article of yours with a link to your target website.
Boom! You’ve got a link from a 10-50 DA website easy. Strategies like this are a great way to build up your ranking in a hurry.
