Does anyone know if the prefetching/prerendering Chrome does is a significant portion of web traffic? Because that could easily skew request-based analytics.

- Tobu 14y agoProbably the page visibility API: https://developers.google.com/chrome/whitepapers/pagevisibility https://developers.google.com/chrome/whitepapers/pagevisibil... Headers wouldn't work, because a prefetch often turns into a page view. Edit: their methodology is public. They use the aforementioned API, and headers for the two other browsers that prerender (Firefox and Safari, who rarely prerender because pages must explicitly configure it). Pages pre-rendered and discarded would add 1.3% to Chrome page views if they weren't discounted. Here is the StatCounter FAQ: http://gs.statcounter.com/faq#prerendering http://gs.statcounter.com/faq#prerendering
- powertower 14y ago> Statcounter claim to adjust for chrome's prefetching It didn't seem to make any non-marginal effect on the graph. I wonder if they can accurately account for the pre-rendering. Of course, pre-rendering might just be that good, that it's always hitting the right pages.
