SMC is a Link exchange program, created to meet the modern way of link exchange on the net today.. This program is far from being first link exchange software, but this is the first program which automatically check links every minute. As soon as yours link partner removes the backlink to your site, yours SMC will remove the link to his site at once. But it does not mean that link partner is lost forever. As soon as link partner renews the link to your site, his link will appear again on your site. As this program checks quantity of the links on the link partner's linkpage, if it contains more than 50 links to other sites, SMC refuses to accept such partnership, as it contradicts the requirements of search systems (search engines). You can also manually add link in the administration. Once a link is added, an automated email is sent to the person you propose link exchange partnership with inviting for a link exchange. Page rank is displayed for all link partners. Customizable email templates. Also this program would check that the address of page where the partner has placed your link met to the domain of a site. This is the link exchange software that you haven't seen yet!
