Google Analytics and the new EU privacy law #1

Categories: GDPR & Privacy / Comments: 43

Following new EU laws aimed at protecting the privacy of online users, there has been much said about the death of web tracking as we know it. At present the wording of the law is stating that visitors to your website must explicitly consent to having cookies stored on their computers. As pretty much all web analytics tools rely on Read more

The FTC Privacy report “Do Not Track” – a missed opportunity

Categories: GDPR & Privacy / Comments: 4

As readers of this blog will know, I am a strong advocate of online privacy... That may sound strange coming from a web analytics evangelist. However, if we as an industry do not sort these privacy issues out, there is a real danger that web analytics as we know it today will disappear completely. So, following the recent excellent post from Phil Read more

Understanding Web Analytics Accuracy – Whitepaper

Categories: GDPR & Privacy, Metrics Understanding, Pro Lounge, Setup Accuracy / Comments: 8

I first wrote about web analytics accuracy in 2007 while working at Google. At that time numerous clients (big spending Google advertisers my team helped) were contacting their Adwords account managers asking why Google Analytics numbers did not match their AdWords click-through reports, or for that matter, match the other web measurement tools they were using. These of course are legitimate Read more

Categories: GDPR & Privacy / Comments: 7

Privacy on the web has always been a contentious issue, as the vast majority of users wish to remain anonymous while browsing. However, little attention has been given to the privacy of mobile phone users. Hence I was interested to read the article on mobile apps from Sarah Perez: www.readwriteweb.com/archives/dear_iphone_users_your_apps_are_spying_on_you.php Compared to computer use, mobile phones have a greater potential to Read more

Why counting uniques is meaningless

Categories: GDPR & Privacy, Metrics Understanding, Setup Accuracy / Comments: 25

The term 'uniques' is often used in web analytics as an abbreviation for unique web visitors (i.e. how many unique people visited my site). The problem is that counting unique visitors is fraught with problems that are so fundamental, it renders the term 'uniques' meaningless. Firstly, cookies get lost, blocked and deleted. Research has shown that after a period of four Read more

Google Analytics Accuracy – Comparing Google Analytics, Yahoo Web Analytics and Nielsen SiteCensus

Categories: GDPR & Privacy, Metrics Understanding, Setup Accuracy / Comments: 16

          Last year I wrote an whitepaper on web analytics accuracy. The intention of this was to be a reference guide to all the accuracy issues that on-site web measurement tools face, and how you can mitigate the error bars. Apart from updating the article recently, I wanted to illustrate how close (or not) different vendor tools on Read more
