Are these links permanent?
PostLinks.com offers both Monthly and Permanent link membership plans. Monthly Link Memberships
Monthly Link Memberships allow you to "rent" your link building credits.
By renting credits, you can easily remove links and use them for other
websites. For more information, click here
.Permanent Link Memberships
Permanent Link Memberships allow you to purchase one-time credits that
can be used to place permanent links. All links are created using
advanced queuing functionality that allows you to specify the minimum
and maximum Domain Authority of the sites and decide whether you want to place your
links daily, weekly, or all-at-once. Then, if any links are removed, the
link is automatically replaced with a comparable link for up to a year. For more information, click here.
