I can see that many people are entering my site looking for a way to block Google Analytics; however, my article on the subject relates to just blocking your own activity, so it doesn't show up in reports and skew the data. From the keywords I see people using, it appears that there is a demand for something that actually blocks Analytics from every site that is visited. As someone involved in Analytics, I find it confusing why anyone would really care about the issue, so I think there may be a misunderstanding about the technology somewhere. I would be very interested in your comments about the subject if you have a different opinion to me.
The only reason I see why people might want to block Google Analytics relates to privacy concerns; however, as far as I'm aware, there are a lot less issues about this with Analytics than there are with other activities, such as using social networking sites etc. Your IP is stored for geocoding, but this is deleted by Google within 24 hours—much less than the logs on many websites. There are also cookies that are set on your browser, but these only store generic data relating to your activity on the site. There's nothing stored that can actually identify you personally, so there should be no real concern about privacy. In fact, Google's policy on the issue is strictly that no personal data should be transmitted to Analytics at all; moreover, my understanding is that they have tight controls on access to specific account data in place by internal employees.
Although the word “tracking” conjures up certain “Orwellian” images in many peoples minds, the actual reason many website owners use it is simply to learn about their visitors so they can make improvements to provide a better service to them. The idea that grown adults can actually be brainwashed into taking actions that they don't want to, such as making purchases, is really quite insulting to their intelligence. One of the main goals I currently have in using Analytics on this site is simply to determine if the content I'm posting is actually any use to people, instead of just being rubbish! Is there anything wrong with that? If there is then you could try something like Ghostery. Maybe you could also leave a comment as I would love to hear what you think!
Update: There is now an official browser plug-in that you can use to block Google Analytics activity.
