A study found that 58% of tech-savvy audiences, such as those from Hacker News and Reddit, block Google Analytics, leading to inaccurate traffic data. This is due to the use of adblockers and privacy-friendly browsers, which can block Google Analytics scripts. The study compared data from Google Analytics and Plausible Analytics, a privacy-focused alternative, to determine the extent of the blockage. The results showed significant differences in traffic numbers between the two analytics tools.
