Answer Question
By how much does Google Analytics under-count a site's traffic?
I was reading up on Google Analytics and apparently it under-counts the page visits on a site for reasons like:
- Blocked Javascript on a browser i.e. if the visitor has disabled Javascript on their browser, Google Analytics cannot detect this.
- Really quick pageviews
On average how large is the discrepancy? 10%, 20%? I've noticed that sites like Alexa and SimilarWeb report significantly more visits to sites than the Google Analytics data shows.
