Looks Can Be Deceptive: Web Analytics & Transaction Log Demystified

A quote from the book helps visualizing the true figures of a Website's visitors:

"One could legitimately wonder if the counted visits appearing in Table 7-6 can be attributed to actual people or to robots, spiders, crawlers and the likes. Robots are usually small applications designed to gather data for search engine indexes. Unfortunately, the record of a virtual visit by a robot, spider or crawler looks no different in a Web server transaction log than that of a visit by an actual person. Robot visits may be traceable through name identifiers (i.e., Googlebot), or by a high volume of pages accessed in a very small timeframe, or by their requests for a file on the Web site called 'robots.txt.' The latter normally describes what may or may not be indexed from a given Web site by search engines. Nevertheless, if found, visits by robots must be systematically filtered and separately counted or just ignored when assessing the real usage impact of a Web site."

Thanks for the insight. Will be happy if you send me an email and that will give us an opportunity to enhance our understanding of fact and fiction.
