Backlink Rhino is an advanced backlinks cloud-based tool that finds you high quality, high authority powerful backlink opportunities: Wikipedia backlinks.
Google loves WikiPedia, getting backlinks from Wikipedia makes Google trust (and rank) your sites/pages/videos
And BacklinkRhino software will find Wikipedia pages where the domain has expired and can be re-registered for a few dollars, just the same as a regular domain.
This kind of backlink is often offered as a service from 'SEO' companies who charge $50-$100+ for just 1 backlink.
With Backlink Rhino you can search for as many as you want, and once you own the domain you have far more flexibility what you can use the backlinks for!
Using just 1 backlink from your own domain linked to from Wikipedia will get you far more Google ranking juice than buying a bunch of low quality links from other services...
