How to Boost your Domain Authority on a budget...
 

Choose your favorite domain. Create five subdomains from your favorite domain. They can be one page each as long as they link back to the main page.

Add all five subdomains to the same invoice at hardlinks.org and check out using paypal. You will be charged $50 for the first month. When you receive your first monthly report cancel your subscription.

Next month add 5 new subdomains to a new invoice and check out using PayPal. You will be charged $50. When you receive your first monthly report, cancel your subscription.


Continue to do this each month and you will end up with about 1,800 backlinks pointing to 60 of your subdomains.

That should certainly boost your domain authority... for 50 bucks per month.
