All of our link packages are based on # of verified links we find within 24-48 hours of posting the 1st time. However, as all content on the web is filtered on a weekly & monthly basis. Not all of these links will be kept alive after 2-4 weeks.
We find that out of every 100 links - you will have 1 verified link that stays in HREFER (a backlink analysis program) and 1:250 in MAJESTIC SEO.
NOTE: Most companies that are looking to rank will need less than 100 links to stick inside MAJESTIC SEO in order to rank PAGE 1,2,3.
