This automatic data entry is one of SelfPromotion.com's most powerful and subtle features. There are many minor indexes out there that might only generate 5 or 10 hits a year for you. It isn't worth spending 5-10 minutes at each of these sites to register by hand, but because the extra information you have to enter to promote to one more site using SelfPromotion.com usually takes you less than a minute to enter, it makes it possible for you to register at more sites than you otherwise would if you were doing it by hand.
It wouldn't be cost-effective for you to spend an extra hour or two of your time doing registrations that might get you an extra 100 visitors a year (and maybe 1 or 2 sales). But if it only took you 10 minutes, it's a different story. Which is the real power of this site. It saves you time.
I have been online for years and this is probably the most functional, useful and well designed site I have ever found. It's a blessing for registering a lot of similar pages quickly. -- Sophia Cornet
Great job on this site! It works great for original and re-submissions, and delivers more accurate results than many other so-called "promotion" companies. -- Jonathan Pajion
You should really be impressed you're getting money out of me. I NEVER pay for ANYTHING, but I am THAT impressed with your site. Keep up the good work. Or I'll kill you. -- Jim P Reardon (aka eviljim)
and my current favorite, which proves my mother was right about guilt being good for you:
I know I don't have to contribute again, but your site has saved me so much time and effort that I feel guilty not giving you more money. -- Paige Louise Young
