There are exclusive downline builders and there are the downline builders included with every other marketing program. Traffic exchanges, list builders, marketer “networks”, etc. They are useful as a slow spring of referrals when you actually fill them with your IDs. But if you’re not prepared, filling downline builders can be an expensive marketing method. Even on a good connection, it’s easy to have a simple fill-in session take up all your “marketing” time.
The solution is having a referral book. I use a cheap 80 sheet notebook marked alphabetically, at least two sheets per letter (three or four sheets for the letter “T” is recommended). When I sign up for something that includes affiliate membership, I write down the domain name on the left and my referral id on the right. When I come across a downline builder, I flip to the appropriate letter for the program’s site domain and look up the referral ID. The flip through the pages is far faster than having to log into different web sites, skip through one-time-offers and other promos, and navigating to the right pages. It also stops the distraction of realizing that a site your visiting for your referral id also has a downline builder too.
