An Excel Report is given to the client detailing the usernames, email addresses, passwords used, your public profile URL ( you can check on this urls the validity of the backlinks) and the corresponding list of keywords and urls used.
Actually, we can finish a single big volume profile order up to 3,000 Profiles in one day if the client wants to. We can just distribute the workload among our more than 25 linkbuilders. However, we do not advise our clients to do too many backlinks too fast because of the risk of the site being penalized by Google. If the client really wants to do linkbuilding heavily in one day, just inform us so we can make the arrangement.
