Backlinks continue to be one of the SEO performance indicators, particularly if you're looking to buy backlinks, get authoritative links, or buy backlink s cheap.
Instead of paying per link, top marketers use expired domains to gain authority at scale — usually through permanent redirects.
These domains are URLs that used to be owned but expired. Once they complete their lifecycle, they become available again — still carrying SEO signals, domain age, and sometimes organic visitors.
Many of these domains maintain authority from reputable sources like Wikipedia, giving you a way to get link power in volume.
After purchasing such a domain, and setting up a 301 redirect, you’re telling Google that the content has moved — and you inherit its backlink profile.
According to Google, no link juice is lost through 301s. That makes the process of using expired domains as powerful as buying backlinks directly.
Start by finding authority-rich expired domains using Ahrefs. Double-check the backlinks are clean, and contextually appropriate.
If everything checks out, register the domain and forward it to your main site. This will transfer SEO value from the expired domain.
To boost results further, combine the 301 strategy with broken link building, giving you a full-stack approach to building SEO backlinks.
Unlike traditional link building — where you pay for each link individually — expired domain redirection lets you get authority links cheaply.
In summary, if you're planning to buy backlinks, leveraging aged domains with real Wikipedia backlinks and clean profiles is one of the most efficient methods to gain authority.
