>Surprisingly, Google Analytics reported only 28.818 visits by users who were redirected from Facebook during this timeframe – i.e. 8,81 percent less. From these users, 3.786 registered on Stackfield. //

Hypothesis: Could that be pre-emptive caching - some browsers IIRC will fetch a page ready for display. GA could be showing displayed pages whilst FB are showing followed links?

On the general situation, what's the rate of false clicks on Facebook - like how many people accidentally click an ad?



Google Analytics doesn't report exact results (unless you pay for it, around 150k I think), 10% of error could be normal. It should be use to measure trends and not exact numbers.


8.8% fewer clicks in GA than what you paid on FB isn't bad, IME.

I'm running a campaign where FB charged me for > 800 clicks. My GA system recorded about 300 clicks.

Slightly under half is about expected whenever i look at numbers. I'm doing remarketing to people who visited my site in the past 7 days, so I'm not sure if that has something to do with it.


Do browsers really preload pages from random links in advertisements that I have no intention of ever clicking? That sounds like a terrible idea.


Step 5 here - https://support.google.com/chrome/answer/1385029?hl=en-GB.

Or https://developer.microsoft.com/en-us/microsoft-edge/platfor...

Looks like Edge only prefetches when specific link tags give prefetch prompts (Resource Actions per W3C specs) whilst Chrome appears to do things more speculatively.

Not sure about IE, FF and other approaches.


I don't know about that, there may be extensions or add ons that provide such features though.

Many browsers will start loading a URL as soon as you type it in, even if you don't press enter however, try this with a local server sometime, it can be a little jarring.
