Glossary term: Rented Links
As opposed to permanent links, rented links are purchased on a monthly basis. The advantage of such links is that one generally receives absolute control over anchor text and deep linking.The disadvantage, naturally, is that one must pay for them every month. And, due to Google's requirement that links be aged, no benefit is received for months after their creation.
Wherever possible, the page from which such links come should match the theme of the key phrases on the page being linked to. If the geographic theme of the page matches that for the site, one might even receive decent direct traffic.
