| Google uses an automated software to go index the whole world wide web. These automated softwares are typically called a spider or crawler. Google indexes your weblogs through the use of these spiders, if you look at the image to the left, you will see a robot that looks like one of the robots you can see in a terminator movie, however a spider isn't really a physical robot, it is only a program or just a set of instructions performed by Google's web servers, A spider or crawler is sent to your weblogs and then reads and records your entire weblogs content. How often a spider crawls your weblogs depends on a lot of factors, one of which is the page rank of your weblogs, another is how often you have added content to your weblogs in the past.
