Ask HN: What percentage of your website visitors block Google Analytics?

I just did a quick analysis of my web server access logs and got a big surprise. I expected that 5-10% of visitors would be blocking Google Analytics, but the log analysis made me think it's more like 50%.

Have you done a similar analysis? If so, I'd love to know:

1. What percentage of your website visitors were blocking Google Analytics?

2. What method did you use to get that figure?

3. What is your website's target audience?

My own answers to these questions are below.

1. 50 - 55%

2. I took the "Users" figure from Google Analytics for a particular day, to get "today's unique visitors according to Google Analytics".

I loaded my nginx access logs for the same day into GoAccess. I took the "Unique visitors per day - including spiders" figure and subtracted the 5% or so of unique visitors whose browser type GoAccess listed as "Crawlers" [i]. That gave me a figure I'll call "today's unique visitors according to GoAccess".

3. University students, graduates and young professionals.

[i] Presumably this doesn't capture all non-human visitors. I'm not sure what further adjustment, if any, should be made here.
