Spiders, Crawlers, Bots, Etc.

Most cheaper analytic packages can give data that is misleading. They might provide you with a "hit counter" or an equivalent visitor counter. However, most of the traffic to your website might consist of automatically generated "web crawlers", "robots", "spiders", etc. that only troll for information. They do not represent real visitors to your site. Knock Knock removes these visitors from your analytic information.
