hi everyone, whenever i happen to read some of the blogs on how to increase our traffic,one thing i come across everytime and that is my question
and that thing is spiders,some say google spiders crawl on the websites and retrieves the link if anybacklinks are there and thus increasing the pagerank.ofcourse they are many issues on implementing the pagerank depending on the backlinks but my question is what are these spiders if my guess is correct these are some algorithms that search the websites.
could any one just elaborate and explain me please.
