diappearing backlinks

One thing to also keep in mind is that to hide their algorithm they will some times remove already established links. Just so that it makes it harder for individuals to reverse engineer their algorithm. If one was able to easily reverse engineer this they would most certainly be able to figure out the most important factors to hold and maintain the number one spot.

A good example of what you are experiencing is like 2 of my sites. I recently bought the same linking package for both sites. One site is about a year and a half old which already had over 2k backlinks in yahoos site explorer. However the other site is only a few months old and shows more backlinks then the other site that already had 2k backlinks. Both sites got the same exact package and the same ammount of backlinks but the older one has less backlinks then the newer one. This is just them covering their --- so you can not reverse engineer there algorithm.

Your best bet is to just monitor your rankings for the keyword your are targeting with your backlinks. Once you stat seeing your self on the front page for your main keywords you can start slowing down the process and start targeting a new keyword. A good way to find a good keyword to help boost the already established one is to use googles wonderwheel. Just type in your main keyword and hit search and activate the wonderwheel in the more search options. This will give you highly relevant keywords related to your main keyword. Which would give you a nice boost for your main keyword if you where to start targeting them.

Some of those keywords may not have a good amount of traffic. But your main concern first should be your first keyword then branching out from there. Once you establish that one keyword it is that much easier to start growing your search based keywords. Since you would have a well established keyword already.
